Senior Engineer - AI & Data Products

Job Description

Senior Engineer – AI & Data Products (Aarhus) 

The Tech Collective, Data & AI 
Kalkværksvej 5, 8000 Aarhus · Full-time 

We’re looking for a senior builder who turns AI and data into products people actually use. You’ve shipped real systems end to end, you know AI or data well enough to make it work in production, not just in a demo, and AI is as much a part of how you build as what you build. 

What you'll do 

In this role, you’ll take client ideas from a rough hypothesis to a working prototype, and then to a production system that runs reliably. You'll design the architecture, write the code across frontend, backend, and data, and decide what to build and what to leave out. It's a hands-on role. Most of your time goes into building, and the rest goes into working with clients to make sure you’re building the right thing. 

The work covers generative AI applications and agents, including the harnesses that make them reliable (tools, context, memory, orchestration, and guardrails), along with retrieval pipelines and the data flows they depend on. You’ll connect these to client systems, deploy them in the cloud, and set up the evals and observability you need to see whether they work and how to improve them. You’ll work closely with our data platform and AI specialists, review code, and help less experienced engineers grow. 

What you'll bring 

You're a builder at heart. You have a master's degree in computer science, engineering, or a related field, (preferably) 5+ years of hands-on software experience, and a track record of shipping production-ready software systems. Ideally, you also have experience with the whole software development lifecycle: starting with an idea (whether your own or a stakeholder’s), designing the solution architecture, developing and testing the solution, and putting it into the hands of actual users. Good engineering matters to you, but you’re not a purist, you care more about shipping something that works and solves the problem. 

What sets you apart is depth beyond the code. You know AI (LLMs, agents, RAG, evals) and data (data modelling, pipelines, event-driven, and real-time systems) well enough that others come to you for it. Ideally, you know a bit of both. 

You're equally at home building AI products and building with AI. Coding agents and AI-assisted tools are part of how you work every day, and you use them critically. You know where they make you faster and where the output needs a careful human eye. 

To be a great fit, it helps if you have: 

• Solid full-stack skills in Python and/or TypeScript (e.g., React, Next.js, FastAPI), with production systems to show for it 

• Hands-on experience building agents and the harnesses around them (tool use, MCP, context and memory management, orchestration, guardrails), and designing the data models and pipelines that real products run on 

• An AI-native way of working, using coding agents such as Claude Code, Cursor, or Codex in your own development workflow, with a clear view of where they help and where they don’t 

• Experience deploying and running solutions on AWS, Azure, or GCP, including containers, CI/CD, and enough observability to know what's going on 

• System-level judgement: you can reason about architecture, trade-offs, and failure modes, and you can spot the weak points in an existing stack 

• Curiosity about the client’s problem, and the ability to explain technical choices clearly to people who don’t write code 

• A habit of helping others get better through sparring, pairing, and code reviews 

English is our corporate language. Proficiency in one or more additional languages is a plus. 

What we offer 

At The Tech Collective, you’ll join a team of 30 consultants that feels closer to a nerdy startup than a large consultancy, while being firmly backed by Implement Consulting Group. You’ll own what you build, and you’ll have the freedom to shape your role in the direction that motivates you. 

You’ll work on data and AI problems across industries, alongside experienced peers in AI, data, and software. Our culture is built on trust, curiosity, humility, and impact, with high autonomy, co-creation, and active knowledge-sharing. 

Ready to build with us? We review applications on an ongoing basis, so apply as soon as you can.
