Join our self-funded SaaS company as an AI Product Engineer. In this strategic role, you will design and develop AI-powered features, build internal agents, ensure technical and functional quality, and connect product and engineering. You will work directly with the executive team and have a significant impact on our product and company.
Responsibilities
- Design and develop AI-powered features, including functional prototypes and integration with APIs.
- Build internal agents and tools for product discovery, specification writing, QA, and ticket analysis.
- Ensure technical and functional quality by defining acceptance criteria, validation plans, and conducting tests.
Requirements
- You have a higher-education qualification in computer science, software engineering or an equivalent technical background.
- You have between two and five years of experience in a SaaS environment, ideally as a Product Engineer, product-minded Software Engineer, AI Engineer or highly hands-on Technical Product Manager.
- You can design and develop a functional prototype from end to end.
- You can read, understand and modify code, and engage in in-depth discussions with an engineering team.
- You are comfortable working with REST APIs, data formats such as JSON, version-control tools such as Git, and the general principles of SaaS architecture.
- You can query and manipulate data using SQL or equivalent tools.
- You are proficient in at least one language suited to prototyping or application development, such as Python, JavaScript or TypeScript.
- You regularly use AI tools to code, design, document, test and analyse.
- You understand how LLMs work and where their limitations lie, including context management, hallucinations, output variability, cost, latency, confidentiality and security.
- You have already experimented with model APIs, orchestration tools, RAG systems or agents. Production experience would be a strong advantage.
- You know how to define metrics and test datasets to evaluate an AI-powered feature beyond subjective impressions.
- You are autonomous, thorough and able to move a project forward even when every detail has not yet been defined.
- You have a strong product mindset and never lose sight of the user problem to be solved.
- You are comfortable working in English, both written and spoken, with international teams, partners and customers.
- What we are not looking for: This is not a traditional Product Manager position focused exclusively on roadmaps, coordination and ticket writing.
- We are looking for someone who is comfortable getting hands-on with technology, building an initial solution quickly, testing its behaviour and working closely with engineers every day.
- You enjoy starting with a user problem and building the first solution yourself.
- You can move from a product discussion to a prototype, and then from a prototype to a production-ready feature.
- You enjoy experimenting, but would never release a solution that cannot be properly evaluated or made reliable.
- You can challenge both product decisions and technical proposals.
- This is not a fundamental AI research role either. Our priority is to turn existing technologies into reliable, useful and deployable features.
- You are likely to thrive in this role if…
- You consider documentation, testing, observability and quality to be integral parts of development.
- You use AI as an accelerator while maintaining a critical perspective on its outputs.
