What you'll do 🏡💻

You'll work across the AI lifecycle, from exploring new models and techniques through prototyping and evaluation to building and running production AI services, working closely with our agentic engineering approach.

• Build and integrate AI and machine learning services into production systems
• Develop agentic workflows that combine models, tools, data and business logic
• Evaluate LLMs, SLMs and specialised machine learning models for specific use cases
• Design retrieval, context and knowledge systems for AI applications
• Review and validate code generated through AI-assisted and agentic engineering workflows
• Work with software engineers, product teams and AI specialists to take ideas from concept to production
• Monitor and improve AI systems once they are live in production

The must haves 💪

• Strong Python skills (or equivalent experience in a language like C) and modern software engineering practices, including building APIs and services
• A track record of shipping AI or software products into production, not just research or prototyping
• Hands-on experience with LLMs or generative AI systems
• Experience with AI agents, tool calling or orchestration frameworks, or with AI coding assistants/coding agents
• Strong engineering judgement, comfortable reviewing, testing and challenging both human-written and AI-generated code: most of our code is written via AI coding agents such as Claude, so this sits at the centre of the role rather than at the edges
• Experience running AI or ML systems in production, including cloud environments and CI/CD

The nice to haves ➕➕➕

• Experience with RAG, embeddings, vector search or knowledge systems
• Background in machine learning or applied data science
• Model evaluation and benchmarking experience
• Practical AI use cases in areas like finance, analytics or speech recognition (ASR)
• Experience in customer experience or contact centre technology
• Comfortable explaining technical ideas to both engineers and non-engineers

The location

This role will be based in our Aarhus or Copenhagen office, with an expectation of 2-3 days/week onsite. English is our working language, so Danish isn’t required.

What’s In it for You? 💰

• Competitive salary based on Mercer salary benchmarking data
• Flexible, hybrid approach to working; split your time between the office and home
• You get to be part of a fun, driven and supportive team
• Annual Summer and Christmas parties
• Excellent development opportunities and a great company culture

What to expect from the interview process ❔

Puzzel Values 🎯

• Built on Trust – trust is an intrinsic Nordic value, upon which Puzzel has been built. We trust each other and our customers and partners trust us.
• Stronger Together – working together in a genuinely collaborative way, with a shared purpose, we have an empowered organisation that is better equipped to delight customers and partners.
• Stay Hungry – have a continuous hunger to raise our game, innovate and be the best we can be professionally.

Diversity & Inclusion 🌍

We want everyone at Puzzel to be their true, authentic selves at work irrespective of nationality, race, ethnicity, religion, sexual orientation, gender identity, physical ability, age, or economic background.

Whilst we are proud to already have a diverse workforce from across the globe, we are aware that things could always be improved – for example, we currently have a ratio of female 26:74 male employees, which whilst not uncommon for the tech industry (average in SaaS is 26% female), it’s far from ideal. So, what are we doing to improve this?

• Our Global Leadership Team (C-suite) has shifted from 100% male to 50 male: 50 female in the past 18 months.
• We have increased our % of female hires from 23.6% in 2021 to 38.5% in 2023.
• We are partnering with the likes of Flexa, who have significantly higher-than-average talent pools of candidates from diverse backgrounds.
• We are working with State Employment initiatives in Norway and Sweden to bring candidates through internship/apprenticeship routes and are investigating similar initiatives in the UK and Bulgaria.
• By raising awareness and transparency, we are hoping to further attract a diverse workforce.

We are continuously striving to foster an inclusive and diverse environment, where everyone is celebrated for who they are. If there is anything we can do to support you in the interview process, or beyond, please let us know.
