Senior Software Developer (m/w/d)

We are actum – a mid-sized IT company with a clear focus: We develop tailored software solutions that precisely reflect our customers' individual processes.

Our solutions arise directly from practice – from long-standing customer relationships and genuine challenges. It's not about quick cost-cutting measures, but about sustainable added value: flexible, scalable, and with fast Return on Investment.

Whether process automation, complexity reduction or UX and prototyping – we accompany our customers with specialized modules and a team that knows where the shoe pinches.

Aufgaben

You are developer, mentor, and architect in one. You recognize problems before they escalate, translate technical requirements into scalable solutions, and bring your team forward through reviews and clear patterns.

Your tasks

• Development and design of backend solutions based on Java & Spring in modern, distributed system landscapes
• Active support for the development team through code reviews, introduction, and establishment of architecture patterns as well as technical guidance for colleagues
• Co-shaping and further development of CI/CD pipelines and deployment processes
• Near alignment with product and project responsible persons – you translate technical requirements into technical solutions
• Proactive identification of risks, technical debts, and improvement potentialities – you wait not until problems escalate
• Integration of systems from various service providers and partners into a consistent overall architecture
• Sovereign handling of KI-based toolchains (e.g. Copilot, agent-based workflows) as well as classical development environments

Qualifikation

Technical Skills

• Very good knowledge in Java & Spring (Spring Boot, Spring Integration or similar modules)
• Solid foundations in Docker & Kubernetes – you understand how your code is deployed and operated
• Experience with CI/CD pipelines (e.g. GitLab CI, ARGO-CD, Helm)
• Safe handling of KI-based development tools (e.g. GitHub Copilot, agent-based toolchains) – and you know when to use them and when not
• Broad understanding of software architecture: Microservices, Event-Driven Architecture, API design, patterns like API-first and Saga are no foreign words for you
• Experience in system integration between different service providers, interfaces, and heterogeneous system landscapes

Soft Skills – just as important to us as the technology

• Very good self-organization: You keep track even in parallel tasks and changing priorities without someone having to ask you extra
• Strong communication skills: You can clearly communicate technical matters, both within the development team and in product and project rounds
• Navigational safety in complexity: You quickly find your way in grown, heterogeneous systems and project structures without losing sight of the big picture
• Team Enablement: You see it as part of your role to enable other developers through reviews, patterns, and constructive feedback – not just closing your own ticket
• Solution-oriented: You analyze problems calmly, prioritize pragmatically, and deliver – even under pressure – executable solutions
• Proactive working style: You don't wait for task assignment, but recognize independently where action is needed, and communicate openly

Benefits

• 30 days of vacation and mobile work
• Subsidies to the Germany ticket and WellPass
• A strong team with genuine cohesion
• Modern office in top location at Hamburg's Speicherstadt

We look forward to your application!
