senior product engineer

Vanilla Steel GmbH

<div><h4 class="jobSectionHeader"><b>Your mission</b></h4><p>
We are a Berlin-based startup transforming how industrial materials are bought and sold across Europe. One of the oldest industries in the world still runs on Excel, PDF and email. We are replacing that with AI that runs the buying and selling workflow end to end, increasing liquidity, speeding up transactions and reducing waste for hundreds of steel and metal distributors.<br>
<br>
We have strong early traction, real enterprise customers and committed investors. We are a lean, technical team scaling our enterprise pilots and building the AI infrastructure underneath them.<br>
<br>
Your job as <b>Senior Product Engineer</b> is to make sure we deliver on that traction and stay ahead. You partner closely with Co-founder Simon, who owns sales; you own that we ship, that enterprise customers succeed, and that the product stays in front. This is a senior, hands-on role with three pillars.<br>
<br>
<b>1. Build and ship with AI</b></p><br>
<ul><li>
Ship production software using AI as a force multiplier &mdash; prototypes, integrations, customer-facing flows &mdash; and get them live, not just specified.</li><li>
Move our AI from assisting people to running the buying and selling workflow as autonomous agents.</li><li>
Integrate our pipeline deep into customer systems and ERPs (SAP, Odoo, Microsoft Dynamics), and design for fast onboarding so a new customer reaches value in days, not months.</li><li>
Our stack: Python, FastAPI, Pydantic AI, Pydantic Logfire, JavaScript/Node, React, GCP, Kubernetes. You won't be expected to master all of it on day one, but you should be comfortable navigating it with AI tooling.</li></ul><b>
2. Lead technical communication with enterprise customers</b><br>
<ul><li>
Own the technical relationship with three to five enterprise customers: run the discovery workshops, scope the work, run first-line UAT, and steer executive, procurement and IT conversations.</li><li>
Translate customer reality into clear build decisions and engineering reality into clear customer expectations. Hold the line on scope when a request will not move the metric that matters.</li><li>
Represent the product credibly to senior stakeholders, and to investors when a customer also sits on our cap table.</li></ul><b>
3. Help build the product org</b><br>
<ul><li>
Drive the shipping cadence: a weekly or biweekly release rhythm with engineering, and sequence delivery against engineering capacity with our Head of Tech.</li><li>
Make the strategic product calls &mdash; what we build next, and what we deliberately do not.</li><li>
As we scale enterprise customers, help grow how the team works and the product function around you.</li></ul><p></p><h4 class="jobSectionHeader"><b>
Your profile</b></h4><p>
You are a builder who ships with AI and can run an enterprise customer relationship and help shape how we build. Two non-negotiables: technical capability and product sense. Everything else sits behind those.</p><br>
<ul><li>
Excellent written and verbal communication in English and in <b>German (C1 or C2 must have, native not required)</b>. You can run a technical workshop with a German industrial customer end to end.</li><li><b>
Berlin-based or willing to relocate</b>. The role also includes regular travel to customer sites in Central Germany (~2&ndash;3 days per month).</li><li>
5+ years building product, with at least 2 years in genuinely technical roles (engineering, technical PM at a real engineering company, solutions architect, forward-deployed engineer).</li><li>
Deep LLM/AI experience: you build and ship real software with LLMs and agents in production, not just prototype or chat with them. You can walk us through something you shipped and how you built it. Bonus if you have shipped an agentic or autonomous system.</li><li>
AI coding tools: you use Cursor, Claude Code or comparable as your primary development environment - not occasionally, but as the way you build. This is how you ship independently without engineering support.</li><li>
Strong technical instincts: you read code, evaluate an architecture, and hold your own in a design review with engineering.</li><li>
First-line UAT discipline: you have personally signed off (or rejected) enterprise releases and can describe the framework you used.</li><li>
Comfortable owning several enterprise customers in parallel without dropping balls, and pushing back on scope when needed.</li><li>
Able to simplify complexity and make fast, sound decisions under pressure.</li></ul><b>
Nice-to-have: </b>background in an AI-first company; ERP integrations (SAP, Odoo, Microsoft Dynamics) or procurement / order-management workflows; early-stage or founding-engineer experience, industrial B2B, metals, supply chain or manufacturing experience.<p></p><h4 class="jobSectionHeader"><b>
Why us?</b></h4><p></p><ul><li>
Ownership of named enterprise accounts, judged on outcomes rather than hours.</li><li>
Direct technical impact: you see what you ship in production within weeks.</li><li>
Senior co-founders who are technical operators, not pitch-deck founders. Decisions happen fast.</li><li>
Competitive base, performance bonus, and meaningful equity at a Series A company.</li><li>
Regular travel to customer sites (mainly Central Germany).</li><li>
Subsidised Urban Sports Club membership and Deutschlandticket.</li><li>
Hybrid work format, office in the heart of Prenzlauer Berg, Berlin.</li><li>
Regular team events, company breakfasts and Friday drinks.</li></ul><p></p><h4 class="jobSectionHeader"><b>
About us</b></h4><p></p><p>

Senior Product Engineer

Pinpoint

<div><h3 class="jobSectionHeader"><b>Description</b></h3><div><br>
Hi I'm Leo, Head of Roadmap Engineering at Pinpoint.<br>
</div><div>We're a high-growth HR tech company building software that helps in-house recruitment teams attract, hire, and onboard the right talent. Today, we have a strong foundation in place, with a mature product, rapid growth, strong product-market fit, and happy customers.<br>
</div><div>We're hiring a Senior Product Engineer on our Marketplace squad: the team behind Pinpoint's usage-based features (reference checks, background checks, one-way video interviewing) and the billing that powers them. You'll sit inside our product engineering org of 30+ people across 8 verticalised squads; Marketplace is a tight team of a product manager, two engineers, and a designer, owning these features end-to-end.<br>
</div><div>Our remit is to help grow the revenue that scales with how much customers use Pinpoint, and much of that runs on third-party services we white-label. So the craft here is integration: wiring up those vendors seamlessly and owning the relationship yourself when something breaks on their side. It's one of the most commercially pointed and most independent parts of the product.<br>
</div><div>You'll be embedded in the problem from the start: understanding real customer workflows, debating trade-offs, shaping solutions, and standing behind them in production, with vendors and edge cases included. There's no separate discovery phase and no &quot;throw it over the wall&quot; model.<br>
</div><div>This isn't a role for someone to just ship what they are told. We want engineers who build in-depth context over time and use that understanding to make better product decisions every day. If you care about owning a problem space, not just shipping tickets, this role was built for you.</div><div></div><div><b><br>
The fine print (but a bit more exciting):</b></div><ul>
<li>This is a remote role (UK, Portugal, Spain, or Poland) with occasional in-person team meetups.</li>
<li>Our product is a configurable, platform-style ATS serving multiple personas: recruiters, hiring managers, and operations teams across a wide range of complex workflows</li>
<li>Our <b>stack</b> is pragmatic and maintainable: Ruby on Rails (6.x), React with TypeScript, PostgreSQL, Sidekiq, and CI/CD via CircleCI (moving to GitHub Actions).</li>
<li>Pinpoint is still very much in startup mode. Priorities shift, not everything is perfectly defined, and we expect people to operate well in that environment.</li>
<li>Curious about how we think and build? <b>Our engineers write about it here</b><b>.</b>
</li><li>Our <b>values</b> actually matter here. We hire people who reflect them in how they work, collaborate, and make decisions.</li></ul><br>
<h3 class="jobSectionHeader"><b>
About the Role:</b></h3><br>
<ul>
<li>
Build full-stack features using Ruby on Rails and React (TypeScript) within a small, focused squad.</li>
<li>Own your product area end-to-end: from real customer workflows and edge cases through to delivery, performance, and ongoing quality.</li>
<li>Integrate white-labelled third-party services seamlessly into the platform, and own the vendor relationship, including hands-on debugging when the issue is on their side.</li>
<li>Contribute to architectural discussions and technical trade-offs, not just implementation.</li>
<li>Help translate product needs and constraints into clean, maintainable solutions.</li>
<li>Review code, mentor others, and raise the technical bar within your squad.</li></ul><br>
<h3 class="jobSectionHeader"><b>
About You:</b></h3><br>
<ul>
<li>
5+ years of professional software engineering experience building production web applications.</li>
<li>3+ years of production experience with Ruby on Rails.</li>
<li>3+ years building React applications in a production environment.</li>
<li>Comfortable working with TypeScript (our frontend codebase uses it throughout).</li>
<li>Background in startup or scale-up B2B SaaS environments.</li>
<li>Fluent with AI-assisted development and able to show how it's changed the way you work.</li>
<li>Comfortable operating in ambiguity and taking end-to-end ownership.</li>
<li>Experience on multi-persona, workflow-heavy SaaS products.</li>
<li>Strong written communication: clear, direct, and able to explain technical decisions to non-engineers and external partners alike.</li>
<li><b>Bonus</b>: deep experience integrating third-party APIs / white-labelled services, usage-based / billing features, and refactoring or migrating systems.</li>
</ul><div>
<br>
<b>FAQs</b><br>
<br>
<b>How are squads structured?</b><br>
Small, cross-functional teams: one PM, one designer, and two to five engineers, each owning a specific area of the platform end-to-end: backlog, quality, performance, and all.</div><div>
<br>
<b>What areas of the product do squads own?</b><br>
Verticals across Workflow, Candidate Experience, Onboarding, Marketplace, Platform &amp; Reporting, and Integrations, plus an AI squad and a Delta squad for fast-moving, complex client work. Engineers join a squad and build deep context there over time.<br>
</div><div><b>How is AI deployed within the team?</b><br>
AI is central to how our engineers work. Most of the team uses Claude Code as their primary tool, and the hard part of the job has shifted from writing code to understanding context, owning outcomes, and knowing when the model is wrong. The engineers who thrive here are high-agency people who spot a problem and go fix it, and who care whether what they shipped actually helped the user. We think our value driver is growth and product strength, not margin, so when AI makes each person more productive, we use that to move faster, not to hire fewer people. Our R&amp;D budget is more than 40% larger this year than last, and we still have more work than people to do it.<br>
</div><div><b>Do engineers do support rotations?</b><br>
No formal rotation. Dedicated support teams handle incoming tickets, though engineers may occasionally help with technically complex issues in their area.</div><div>
<br>
<b>What does 'senior' mean here?</b><br>
You're a strong individual contributor who takes real ownership, contributes to technical direction, and helps raise the standard of the people around you. This isn't a people-management role.<br>
</div><div><b>What's the sprint cadence?</b><br>
Two-week sprints, with retros and small postmortems.<br>
</div><div><b>How do you handle QA and technical debt?</b><br>
Quality is owned by the team. We have strong automated testing and encourage engineers to address technical debt as part of their day-to-day work, not in a separate cleanup sprint.<br>
</div><div><b>What does the first 90 days look like?</b><br>
By 30 days, you're comfortable with the codebase, the stack, and Marketplace's product area, and starting to help field questions about your features. By 60 days, you're shipping independently, contributing to squad planning, and influencing product decisions. By 90 days, you're a trusted owner of your area: making technical decisions, owning a vendor relationship, and building genuine product context.</div><h3 class="jobSectionHeader"><b><br>

We&rsquo;re a high-growth HR tech company building software that makes hiring faster, fairer, and more human, fixing the broken processes that make it hard for great candidates and great companies to find each other.<br>

Founded in 2018, we bootstrapped our way to 500+ customers and &pound;5M ARR before raising private equity funding in 2023 to support our next stage of growth. Today, we&rsquo;re a 90-person team across the U.K. and U.S., serving more than 1,000 organizations worldwide. We scale deliberately, with sensible unit economics and no layoffs, because we&rsquo;re building for the long term&mdash;not the next funding round.<br>
<br>
Our product is deep and configurable enough to support complex hiring workflows, yet simple enough for teams to love using every day. That balance is what makes Pinpoint different. We back it up with genuine care, including fast (under 90 seconds) support from real people who know the product.</div><div>
<br>
Our culture is built on genuine transparency and <b>values</b> we actually use to make decisions. Even as we&rsquo;ve moved past early-startup noise, everyone here still shapes how we operate&mdash;taking ownership, staying curious, and solving problems proactively. As we scale, we balance structure with flexibility while holding ourselves to a high bar for respect and kindness.<br>
</div><div>If you&rsquo;re excited by meaningful problems, high ownership, and working with smart, kind teammates, we&rsquo;d love to hear from you.</div></div>
