Senior Platform Engineer HiveAI

At a glance

You'll join an international team of experienced software engineers building HiveAI itself: the platform, services and reusable capabilities that every solution on top of it depends on. One focused team, not a department, spread across several countries and working remotely by default.

On the practical side, you'll be employed through the Dutch Fellowmind organisation, so we're looking for someone based in the Netherlands. Beyond that, where you work is up to you. There are no fixed office days, and our offices in Amersfoort, Deventer, Zwolle and Venlo are there whenever you feel like working alongside people.

• Work experience: 5+ years

• Working hours: 32–40 per week

Build the platform behind Enterprise AI

At Fellowmind we're building HiveAI: a platform for developing, deploying and operating AI solutions at scale. It gives our customers one secure, scalable foundation for enterprise AI, instead of a collection of pilots that never quite make it to production.

As a Senior Platform Engineer on HiveAI, you won't be building customer-specific solutions. You'll build the platform those solutions run on: the services, frameworks and reusable capabilities that let every team downstream move faster. You take architectural designs and roadmap initiatives and turn them into production-ready software.

As a key Microsoft partner we build on their stack by default, and being close to it means we get our hands on new capabilities early. But we're not dogmatic about it. Where the best tool for a problem sits outside the Microsoft ecosystem, we use it, and you'll have a say in those calls.

It's a role for engineers who like solving a problem once, properly, so that a dozen teams never have to solve it again.

What you'll do

• Design and develop core HiveAI platform capabilities

• Build reusable services, APIs, frameworks and accelerators

• Translate architectural designs into scalable technical solutions

• Develop integrations with Microsoft AI and cloud technologies

• Improve platform performance, security, reliability and scalability

• Implement monitoring, observability and operational tooling

• Validate new ideas through prototypes and proofs-of-concept, and turn the promising ones into production features

• Help shape our engineering standards, code quality and best practices

You'll work closely with our architects and fellow engineers to evolve the platform, with a consistent focus on quality, maintainability and automation. The stack moves quickly, so we'd rather talk it through with you than pin it to a list that's out of date by the time you read it.

Who you are

You're a software engineer who enjoys building platforms and untangling complex technical problems. You're curious about where AI technology is heading, and you get satisfaction from building things other teams adopt and rely on.

You bring:

• 5+ years in software, platform or cloud engineering

• Deep development skills in at least one modern language. We work mostly in Python, TypeScript and C#, in that order, but we're not looking for a fluent match: engineers who've reached this level have picked up languages before and will again

• Experience building cloud-native solutions on a major cloud platform (we run on Azure, but the concepts transfer)

• Experience with DevOps, CI/CD and modern engineering practices

• A track record of owning technical decisions, not just implementing them: you've designed systems others build on and lived with the consequences

• Professional
