Kaiko Systems GmbH

<div><p>Kaiko Systems is a Berlin-based maritime technology company making global shipping safer and smarter. Our AI-powered platform helps shipping companies digitalize vessel inspections, compliance, and fleet health, and is trusted by 40+ customers worldwide. In 2026 we joined forces with UniSea, a leading Norwegian maritime software provider, combining startup pace with the strength of an international group.</p>
<p>
We are now looking for a Tech Lead to run our Berlin engineering team day-to-day: a hands-on engineer who prototypes the hard problems, allocates the right people to the right work, mentors the team, and turns architectural direction from our CTO and VP Engineering into a plan the team can execute on. You will report directly to the CTO.</p>
<h2 class="jobSectionHeader"><b>
Tasks</b></h2>
<ul><li>Prototype the hard problems yourself. When product direction is unclear, you write the spike: small, ugly, fast, built to surface the real complexity. You hand the load-bearing core to the team, stay in the loop while they scale it, and defend the architectural choices that came out of the prototype.</li>
<li>Run the team day-to-day: standups, 1:1s, performance conversations, hiring loops, the engineering side of the on-call rotation. You set the cadence and the cadence holds.</li>
<li>Allocate engineers to projects based on real knowledge of their strengths, weaknesses, and where they need to grow. You make those calls and you defend them.</li>
<li>Mentor and grow people. Give hard feedback the day it is relevant, not at review season. Spot the engineer who is stuck and unstuck them.</li>
<li>Extract architectural guidance from the CTO and VP Engineering and turn it into a plan the team can execute on. Architectural decisions sit with them; landing those decisions sits with you.</li>
<li>Stay hands-on: write production code, review the hard MRs, defend simplicity over premature abstraction, push back on shipping blockers.</li>
<li>Continuously improve how we work &mdash; engineering process, tools, standards &mdash; as we grow within the UniSea Group.</li>
</ul><h2 class="jobSectionHeader"><b>Requirements</b></h2>
<ul><li>2&ndash;5+ years leading or managing a team of engineers; you have hired, mentored, given hard feedback, and made calls that did not work and learned from them. Depth matters more than years.</li>
<li>Engineer first in your identity. You enjoy the code, you read other people's code, and you have strong, defendable opinions on language and framework choice, testing posture, and abstraction level.</li>
<li>Genuinely hands-on. Strong on at least one of: Python / Django, TypeScript / React, infra (Docker / Postgres / cloud). Comfortable reading the others. You can still write production code today.</li>
<li>Earned soft skills. You can disagree with senior people and have them think more of you afterward. You can give an engineer feedback that lands. You can read a room.</li>
<li>Real track record of growing people. You can name engineers who grew under you, what they grew into, and what you did to help.</li>
<li>Resource-allocation instinct based on real knowledge of people, not a spreadsheet.</li>
<li>Rapid-prototyping reflex. When you do not know how hard a piece of work is, your instinct is to write code, not to schedule a meeting.</li>
<li>Production-grade taste. You know the difference between a spike and a shippable system, and you build prototypes that can grow into the real thing without a full rewrite.</li>
<li>Fluent English. German is not required.</li>
<li>Based in Berlin or willing to relocate. Flexible on office attendance, but close enough that &quot;hey, let's meet tomorrow&quot; actually works.</li>
</ul>
<p>Nice to have</p>
<ul>
<li>Maritime, logistics, or other physical-world-meets-software domains.</li>
<li>Computer-vision or LLM-agent product experience.</li>
<li>Experience at profitable or capital-efficient companies; we are not a &quot;raise and burn&quot; shop.</li>
</ul><h2 class="jobSectionHeader"><b>Benefits</b></h2>
<ul><li>Real ownership of a ~10-engineer team shipping to global shipping operators.</li>
<li>A codebase that does serious work: AI on the customer path, offline PWA syncing event-sourced state from on-vessel installations, computer-vision pipelines on production traffic.</li>
<li>The stability of an international group (UniSea) combined with the speed and ownership of a startup.</li>
<li>Direct exposure to the CTO and CEO; in the room for the calls that matter.</li>
<li>A diverse, international team of maritime experts, engineers, and commercial talent.</li>
<li>Central Berlin office at M&uuml;nzstra&szlig;e (Mitte).</li>
<li>Competitive salary, meaningful equity, modern equipment.</li>
<li>Regular team events, offsites, and a culture that takes itself seriously without being stiff.</li>
</ul>
<p>We would love to hear from you. Send us your CV plus a short paragraph telling us: (a) the hardest team-management call you have made, (b) a project where you prototyped something and handed it off, and (c) an engineer who grew under you and what they are doing now.</p>
<p>
Our process is fast and respectful of your time: an intro call with the VP Engineering or CTO, a deep technical conversation with the CTO, two team conversations with senior engineers, and a final chat with the CEO. You will hear back from us within a few days at every stage.</p></div>

Senior Software 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>
We are a Berlin-based startup that has successfully established a leading digital-first trading company for industrial metals across Europe.</p><p>
The multi-billion-euro metal trading industry is operated on Excel, PDF and Email. Our mission is to integrate smart technology and data to drive every decision, transaction, and workflow in the steel industry. Our technologies &amp; services increase liquidity, accelerate transactions, reduce scrapping rates and enhance trading convenience for hundreds of steel and metal distributors across Europe.</p></div><p></p>

<h2 class="jobSectionHeader"><b>
Our humble expectations</b></h2>

We're looking for engineers who have experience with most of the following:</p>
<ul>
<li>Strong experience building Android applications with Kotlin</li>
<li>Experience designing scalable mobile architectures and shared platform components</li>
<li>Good understanding of the Android ecosystem and modern development practices</li>
<li>Experience with CI/CD, automation or developer tooling</li>
<li>Strong software design and system thinking</li>
<li>Experience collaborating across engineering teams and influencing technical decisions</li>
<li>Comfortable mentoring other engineers and driving technical initiatives</li>
<li>Excellent communication and stakeholder management skills</li>
</ul>
<p>We'd especially love to meet engineers who:</p>
<ul>
<li>Use AI regularly as part of their engineering workflow</li>
<li>Have experimented with modern AI development tools such as Claude Code, Cursor, Gemini, Codex, Copilot or similar</li>
<li>Are curious about agentic development workflows and AI-assisted software engineering</li>
<li>Know when to trust AI, when to challenge it, and how to build reliable engineering workflows around it</li>
</ul>
<p>You'll stand out if you've also worked with areas such as Kotlin Multiplatform (KMP), server-driven UI, experimentation frameworks, mobile observability, or large-scale consumer mobile platforms.</p>
