Fullstack Software Engineer (with Java)

Project overview

Join a team building software that supports the energy transition and tackles real engineering challenges. We’re looking for a mid-level engineer who values code quality, enjoys learning new domains, and wants to grow while working with modern cloud technologies.

Requirements

Your experience with the additional technology stack does not have to come from commercial work – personal projects, open-source contributions, or academic experience are also welcome.

• Mid-level commercial experience in software development
• Commercial experience with Java 17+ with at least one of the following technology stacks:
• Spring / Spring Boot
• TypeScript with Node.js
• C# with .NET / ASP.NET Core
• Knowledge of AWS and serverless/cloud-native architectures
• Knowledge of HTTP and REST API design
• Knowledge of programming principles and design patterns
• Experience with unit and/or integration testing
• Working knowledge of SQL databases
• Strong English and Polish communication skills (minimum B2), both written and verbal. You'll be working directly with international clients and cross-functional teams, so clear communication is essential

Nice to have

What We Offer:

What we value just as much as technical skills is an engineering mindset:

Be charged up.

• Experienced in using AI tools in day-to-day workflow
• Understanding of asynchronous communication and messaging systems (e.g. RabbitMQ, Kafka, or cloud-native solutions)
• Familiarity with Docker and containerized applications
• Exposure to Kubernetes
• Experience with NoSQL databases; knowledge of CI/CD pipelines
• Real, meaningful work. Our projects directly support the energy transition, and the engineering challenges that come with them are anything but trivial.
• An environment for ambitious engineers. You’ll be challenged and supported in equal measure, with a clear development path and regular feedback to keep you growing.
• Mentorship from experienced engineers and consultants who've been where you're heading.
• Hands-on exposure to modern cloud architectures, distributed systems, and complex integrations from day one.
• A collaborative team that shares knowledge openly and genuinely cares about collective success.
• You care about code quality and maintainability, but you also know when to move fast and when to slow down and get it right.
• You are comfortable with change and ambiguity and can navigate new domains.
• You enjoy working across different stacks and client contexts, and can jump into unfamiliar territory and figure things out.
• You have a client-first mindset and can build long-term partner relationships, not just deliver features.
• You take initiative: mentoring a teammate, shaping a technical decision, or improving how we work.
• You naturally share knowledge and learn from others.
