Position Overview:

This is a vacancy for a hybrid or on-site role at our HQ in Tutzing (South of Munich) or Amsterdam. We encourage applications from all qualified candidates, regardless of gender identity.

As we continuously expand and improve our Data Platform, we are seeking a Senior Software Engineer m/f/x (Java & Networking focus) to join our Engineering department. This department is responsible for the design, development, and growth of our Data Platform as well as our Data Network and connected Data Products. We are looking for key engineering talent with deep backend expertise and understanding of integration & transport layers to join our teams.

You will be responsible for designing and implementing robust, high-performance backend systems, working closely with senior engineers on low-level networking infrastructure, data transport, and platform scalability. We are a team that actively embraces AI as a force multiplier - not just for writing code, but for rethinking how we work.

Ready to make an impact?

You’ll get to take ownership of:

Developing, testing, and deploying core backend components of our Data Platform, with a focus on performance, reliability, and scalability.
Designing and implementing network-layer solutions in Java, including HTTP tunnelling, TCP/IP communication, and Netty-based pipeline architectures.
Building and maintaining load balancing strategies and understanding their role in distributed, high-availability systems.
Designing integrations that combine cloud systems with on-premises data sources with a seamless operations experience.
Contributing to technical designs and actively participating in code reviews to ensure clean, maintainable, and production-grade code.
Actively integrating AI tools into your engineering workflow-using them to accelerate engineering, automate repetitive tasks, improve code quality, and explore solutions faster. We’re looking for curiosity and initiative here - not just the ability to rely on autocomplete.
Collaborating closely with QA and Product teams to deliver reliable, high-quality releases.

We’d love to meet someone with:

Around 3–6 years of experience in backend development, with strong hands-on skills in Java.
Solid understanding of Java networking internals-including NIO, sockets, HTTP/HTTPS tunnelling, and proxy protocols.
Practical experience with Netty or similar async networking frameworks (e.g.Vert.x, gRPC); ability to reason about event loops, channel pipelines, and non-blocking I/O.
Knowledge of load balancing concepts - L4/L7 load balancing, connection pooling, health checks, and failover strategies.
Strong debugging skills and a structured, solution-oriented mindset - particularly when dealing with low-level networking or concurrency issues.
Solid experience with test automation (e.g. JUnit, Mockito, or similar frameworks) and a commitment to well-tested, maintainable software.
Hands-on experience with at least one database technology: PostgreSQL, Oracle, MSSQL, MySQL, or MongoDB.
Good understanding of integration protocols: HTTP/HTTPS, REST, WebSocket, orgRPC.
Confidence with concurrency and multithreading in Java-thread safety, executors, reactive patterns.
Some exposure to asynchronous messaging systems (e.g.Kafka, AMQP, MQTT).
A proactive attitude toward AI-augmented engineering-you actively use AI tools (LLM assistants, code generation, automation agents, etc.) to improve your own productivity and the quality of your output. You think about where AI can reduce friction in your workflow, and you bring that mindset to the team.
Familiarity with TypeScript is a welcome plus, but not a requirement.
Clear communication skills in English; sufficient German for everyday collaboration is a welcome plus, but not a requirement.

You can look forward to:

Opportunity to work flexibly from home
Modern offices in Germany and the Netherlands
A personal Learning & Development budget
Up to 30 days of remote work per year from any EU country
2 additional paid days off on Christmas Eve and New Year's Eve
Company Pension plan
30 vacation days a year
Location-specific benefits packages (your recruiter will be happy to provide more details during your first chat)
Company-sponsored business travel

For this role, we are open to working with specialists based in Germany or the Netherlands. Whether you prefer working on-site at our offices in Tutzing, Amsterdam, or remotely from a location within one of these countries, we’re happy to accommodate your preferred working style.

If you’re excited about this role but don’t meet every qualification, we encourage you to apply!

Lobster is an equal opportunity employer. We are committed to fostering a diverse and inclusive environment where empathy and respect guide our interactions.
