Fullstack Software Engineer (with Java)

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

• 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

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.

• 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

• 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

What We Offer

• 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.

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

• 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.
