Applied AI Engineer

TLDR: We’re looking for top 1%, high agency, AI-forward engineers to be part of our early team at Resonance in Berlin. We have recently raised one of the largest ever European seed rounds, with investment from Anthropic and Hg Capital, to deploy AI into the economy and rebuild businesses for the AI era. You’ll work at the frontier and solve real problems in an environment that champions ownership, autonomy and innovation at pace.

Who we are

Resonance is an applied AI company. We have recently raised one of the largest ever European seed rounds, with investment from Anthropic and Hg Capital. Our mission is to close the AI diffusion gap and rebuild businesses for the AI era. We're looking to hire Europe’s elite AI talent, and we're building our Berlin hub to serve clients across Germany, Austria and Switzerland.

Why now

We believe the economic diffusion of AI is the major challenge of the next decade. Foundation models are advancing far faster than organisations can absorb them; the bottleneck is embedding AI deeply into the core processes of a company to drive an inflection in pace and create organisational advantage. Europe is falling behind on AI, and we exist to help its businesses build real, defensible advantage from it rather than simply adopting it.

The role

As an Applied AI Engineer in Berlin, you’ll build the production AI systems behind Resonance’s client engagements across DACH, driving a dramatic acceleration in productivity or a step change in growth for our key clients. You will work at the AI frontier alongside Senior AI Engineers, owning features, integrations and evals end to end. You’ll build and ship agentic systems, from agents and MCP servers into client systems to retrieval and the product around them, working across the stack from data pipelines and the AI layer to the client’s core systems and the interfaces people use. You’ll build evals and observability from day one, take features from first prototype to production, and deploy and extend what we build inside client environments, shipping at pace with the latest AI coding tools. You’ll grow with the firm by contributing to Resonance’s own AI products and shared platform, turning what you learn on each build into reusable components, and taking on more ownership as you grow.

What we’re looking for: You have extreme agency and a bias for action, thrive on ambiguity, and are AI-obsessed, getting hands-on with new models and tools the day they hit the market. You typically have up to four years building software at a startup, a scale-up, a fast-moving product team or your own company. You write production Python or TypeScript, have shipped software with an LLM at its core, at work or on your own projects, and have iterated on prompts, agent loops and evals. You’re at home with messy real-world data, APIs and SQL, you ship fast without cutting corners, and you enjoy solving problems with technical and non-technical people. You have consistently been among the top performers in high-performing environments, at university or at work. Forward deployed experience, AI side projects or a company you founded are a plus, and so is German for client work in DACH.

What we offer: Competitive total compensation plus equity. Most engineers get one shot at a startup. Here you build many products, not one: our own AI products and platform, and several production AI systems a year across industries. You’ll learn fast alongside people who have embedded AI into 50+ businesses, with scope that grows as fast as your impact. Europe is falling behind on AI, and every build moves another European business to the right side of the productivity chasm. As one of our first engineers in Berlin, you’ll shape how we build, operate and grow.

Logistics: Berlin, 3+ days a week in the office or at client sites, mostly in DACH and Europe. English is our working language; German is a plus. We can sponsor visas for eligible candidates, and start dates are flexible.
