Senior Machine Learning Engineer

Tibber

<div><p><i>We're at a pivotal moment for both Tibber and the planet. When joining Tibber, you won&rsquo;t just help scale a forward-thinking tech company &ndash; you&rsquo;ll contribute to a real shift in how people consume electricity. With millions of smart devices connected to the Tibber platform (like electric vehicles and smart thermostats), we have one of the most unique energy trading portfolios on the market.</i></p><p><i>
We&rsquo;re looking for a Senior Ai Platform Engineer to join us in making the energy transition happen &ndash; maybe that&rsquo;s you?</i></p><p></p><p><b>
Job Mission
</b></p><p>As a Senior AI Platform Engineer, you&rsquo;ll join the Agentic Enablement side of our Platform team and help build the technical foundation for how Tibber adopts and scales agentic systems across engineering.</p><p>
Your focus will be on the architecture, workflows and trust infrastructure that allow AI agents to safely support software development - from writing and testing code to reviewing changes, triggering workflows and knowing when to involve a human.</p><p>
This is a platform role, which means the engineers building agents at Tibber are your users. Your success is measured by how quickly and confidently they can move from idea to production without needing you in the room.</p><p>
This role is for someone who enjoys building reliable systems, thinking deeply about architecture and helping teams adopt new ways of working with confidence.</p><p></p><p><b>
What you'll do
</b></p><ul><li><p>Contribute to the design and architecture of Tibber&rsquo;s agentic development platform, including orchestration layers, platform integrations, feedback loops and escalation paths, and the developer-facing CLI and onboarding experience.</p></li><li><p><br>
Take ownership of key platform components, from design and implementation to reliability and continuous improvement.</p></li></ul><ul><li><p>
Help define workflows, quality standards and ownership models for how agents can write, test, review and support code.</p></li><li><p><br>
Help shape safe and reliable agentic workflows, including human-in-the-loop boundaries.</p></li><li><p><br>
Build trust infrastructure that makes agentic systems observable, secure, reversible and reliable in production.</p></li><li><p><br>
Work closely with Staff Engineers and the wider Platform team to build on Tibber&rsquo;s AWS, Kubernetes and infrastructure foundations.</p></li><li><p><br>
Bring people along through clear technical communication, thoughtful collaboration and strong engineering judgment.</p></li></ul><p></p><p><b>
What we're looking for</b></p><p>
You are driven by impact and know how to turn strategy into execution. You're used to fast-paced environments and thrive when given clear goals and high accountability.
<br>
<br>
<b>We believe you'll thrive here if you:</b></p><ul><li><p>
Bring hands-on production experience building and running reliable agentic software systems.</p></li><li><p><br>
Treat evaluation as a first-class engineering concern, you&rsquo;ve built eval pipelines for non-deterministic systems, whether LLM-as-judge, regression suites, or golden datasets, and know that measuring agent quality in production is an ongoing discipline, not a launch checklist.</p></li><li><p><br>
Bring hands-on production experience building and running reliable agentic software systems.</p></li><li><p><br>
Have strong infrastructure knowledge across Kubernetes, Terraform, Infrastructure as Code, and platform networking.</p></li><li><p><br>
Demonstrate strong software engineering depth in TypeScript, with the ability to own and operate services end-to-end.</p></li><li><p><br>
Enjoys to communicate technical directions and collaborate with engineering teams to enable adoption, and turn platform capabilities into real impact.</p></li><li><p><br>
Apply a strong security mindset to agent permissions, least-privilege designs, and blast radius awareness.</p></li><li><p><br>
Have working knowledge of Model Context Protocol (MCP), evaluation frameworks, or cloud capabilities like AWS Bedrock.</p></li></ul><p></p><p><b>
&zwj;️&zwj;️The Tibber Mindset</b></p><p><i>
Tibber exists to drive energy independence - away from fossil dependency. Our tech helps hundreds of thousands of households shift their electricity consumption to more sustainable and affordable hours - from electric vehicles to smart thermostats, all connected to the Tibber platform. We strengthen the resilience of the grid. Not in theory. In everyday life.</i></p><p><i>
We win, fail, and grow together, staying curious and pushing for better every day. AI is shaping how we work - and we're on a journey to make it central to everything we do. The further we go, the more our Tibberinos matter - and yes, that's what we call ourselves!</i></p><p><i>
Started by two founders in 2016. Now 300+ Tibberinos across Stockholm, Oslo, Berlin, Amsterdam, and F&oslash;rde. And we're still just getting started.</i></p><p><i>
You're welcome at Tibber for who you are. We hire for what you can do and how you think - not your background or where you've been. Diverse teams build better products, and we mean that.</i></p></div>

Senior AI Platform Engineer

Xomnia

<p></p><div><h3 class="jobSectionHeader"><b>Senior Data Platform Engineer</b></h3><p>
At Xomnia, Senior Data Platform Engineers don't just build systems. They define how data platforms evolve. As a Senior Data Platform Engineer, you will set the architectural direction that enables organizations like KLM, Enexis, and Rabobank to operate at the frontier of data and AI.<br>
<br>
You build with conviction: shaping standards, steering technical trade-offs, and leaving a lasting mark on both client platforms and the broader engineering culture at Xomnia.</p><p></p><h3 class="jobSectionHeader"><b>
Lead architecture that others build on</b></h3><p>
Joining Xomnia means entering a community of over 20 nationalities driven by one shared ambition: using data and AI to solve problems that actually matter.

What the role looks like in practice</b></h3><p>
Your week moves between our Amsterdam HQ on Raamstraat with its canal views, uneven floors, and the kind of Friday design sessions that actually move things forward, client environments, and home. At senior level, you're as likely to be leading a migration architecture discussion as you are optimizing a pipeline that processes millions of records overnight.</p><p>
Some examples of the type of work we do: a cloud platform overhaul at a.s.r, a data infrastructure project at DAF, and an end-to-end solution at Albert Heijn.</p><p></p><h3 class="jobSectionHeader"><b><br>
What you bring to the table</b></h3><p>

Deep expertise optimizing pipelines for performance, reliability, and cost, at a scale where it matters.</li><li>
An excellent understanding of technology trade-offs in data platforms specific to a wide range of different use cases.</li><li>
Proficiency with Infrastructure as Code (e.g., Terraform) and CI/CD-driven data workflows.</li><li>
Fluent in English; Dutch is a strong plus.</li><li>
Eligible to work in the Netherlands.</li></ul><h3 class="jobSectionHeader"><b>
What's in it for you?</b></h3><p>
Xomnia invests in the people who push things forward. For Senior Data Platform Engineers, that looks like this:</p><ul><li>
A monthly salary between &euro;5,650 &ndash; &euro;6,800 (based on 40 hours, excluding vacation allowance), plus Stock Appreciation Rights to share in what we're building together.</li><li>
A dedicated &euro;5,000 annual development budget, access to Learning Labs, and real internal influence over how Xomnia engineers.</li><li>
25 vacation days, with the option for unpaid leave or the occasional stint working from abroad.</li><li>
Company trips that range from ski slopes to Jordan, regular canal boat rides, and a Raamstraat office stocked with healthy lunches and a fully loaded bar, every day.</li><li>
A solid pension scheme and flexible working arrangements.</li></ul><h3 class="jobSectionHeader"><b>
Hear it from our engineers!</b></h3><p>
All nicely said, right? But what if you hear these words from our Data Engineers themselves? Our consultants Sara and Wesley talk about their role as Data Engineer at Xomnia and explain why working at Xomnia is so lively.</p><p></p><h3 class="jobSectionHeader"><b>
Become a Xomnian!</b></h3><p>
At Xomnia, we believe in using data and AI to tackle real-world challenges. With a team of passionate experts from 20+ nationalities and over 30% female representation, we celebrate diversity and welcome different perspectives.</p><p>
