Team Lead Enginnering Platform - Kotlin, AI & DevOps

Team Lead Enginnering Platform - Kotlin, AI & DevOps
Build the platform. Shape the architecture. Lead from the front.
What do millions of users, a fast-growing e-commerce business and some genuinely interesting engineering challenges have in common?
You.
Our client is an established international digital e-commerce company with around 350 employees — but this is far from a traditional online retail environment. Behind the products is a sophisticated technology platform handling scale, complex integrations and critical business processes.
And they’re not standing still.
New digital business models are being built, start-ups are being supported and emerging technologies — including AI — are being explored to create what comes next.
This is where you come in.
What you’ll be working on
Lead and grow a high-performing, product-oriented backend engineering team
Take ownership of core B2B platform services used at significant scale
Shape architecture and make important technical decisions with your team, not for your team
Stay hands-on: write code, solve problems and get into the details
Build and operate microservices following a true “You build it, you run it” mindset
Design secure, scalable and maintainable systems with tangible business impact
Partner closely with Product Management and other engineering teams
Define and align APIs, interfaces and architecture across the wider platform
Explore and drive AI-assisted development, including modern agentic AI approaches
Help raise the engineering bar through better tooling, practices and ways of working
The technology
If you enjoy modern backend engineering, there’s plenty here to get your teeth into:
Kotlin · Spring Boot · Microservices · Kubernetes · MongoDB · PostgreSQL · REST APIs · Event-Driven Architecture · Kafka · AI-assisted Development · DevOps
What you bring
Proven experience leading and developing engineering teams
An empowering leadership style — trust and autonomy over micromanagement
Strong hands-on experience with Kotlin and Spring Boot
Experience working with MongoDB and/or PostgreSQL
Solid understanding of microservices, Kubernetes and production systems
Experience designing and working with REST APIs and event-driven architectures
Ideally, hands-on experience with Kafka
A genuine interest in how AI can change the way software is designed and built
Experience with agentic AI development practices is a bonus
What’s in it for you?
You’ll get the freedom and trust you’d expect from a modern engineering organisation, backed by the stability of an established international business.
30 days’ holiday + unlimited additional vacation days
Hybrid working and workation opportunities — typically just 3 days per quarter in the office in Hamburg, with travel expenses covered
€1,500 annual learning & development budget
€30 monthly mobility allowance + bike leasing
Company pension scheme
EGYM WELLPASS for just €25 personal contribution per month
A culture built around trust, ownership and freedom to make decisions
Why this role?
Because great Engineering Leads should be more than people managers.
If you want to stay technical, influence architecture, build great engineering teams, experiment with AI and see the impact of what you build, this role gives you the space to do exactly that.
You’ll have the opportunity to bring together people, product and technology — and actually shape all three.
If that sounds like the kind of engineering challenge you’ve been waiting for, we’d love to hear from you.
