Senior Software Engineer (m/f/d) in Berlin or Konstanz
Berlin, Konstanz
Full-time
Permanent employee
Mission
Your main focus will be to own and drive the delivery of complex backend features, shaping the technical direction of the team and raising the engineering bar across KNIME's cloud platform.
Role Overview
As a Senior Software Engineer, you will own complex backend components (Java or Golang) end-to-end, from technical discovery through long-term maintenance, and drive technical design with high autonomy. You will collaborate with product managers, architects, and other engineering teams to ensure solutions meet both product and business requirements, making informed trade-offs between performance, scalability, and maintainability. You will also act as a technical anchor for the team: mentoring engineers, identifying technical debt and architectural risks, and shaping the team's technical direction and engineering practices.
Responsibilities
Drive technical design, frame and solve problems that span service and system boundaries
Design, implement, review, maintain, and test secure Java-based microservices powering the KNIME cloud platform
Build and improve lean and robust REST APIs
Identify technical debt, security issues, architectural risks, and lead mitigation efforts
Lead the debugging of complex cross-component production issues
Set high standards for code quality, design patterns, and engineering practices across the codebase
Partner with architects, other teams, and product management to ensure technical solutions meet product and business requirements
Provide mentoring and direction for other team members
Research, identify, and present patterns and technologies relevant to software architecture and product design
Actively contribute to cross-team engineering communities and shared technical standards
Requirements
Degree in computer science or a comparable field
5+ years of experience designing and implementing large-scale applications
High proficiency in either Java or Golang, with intermediate-level experience in the other, focused on backend development
Microservice design, development, and deployment experience
Experience with at least one cloud platform (AWS or Azure), including load balancing, scaling, networking, and security
Familiarity with relational databases and data modeling for scale
Experience with Kubernetes and containerization
Familiarity with authentication/authorization technologies (e.g. OIDC, Keycloak)
Strong oral and written English communication skills
Experience with AI-driven software engineering is a plus
Familiarity with event-driven system design is a plus
Practical experience with Quarkus or Helm is a plus
What Success Looks Like
KNIME's cloud platform is powered by a robust, scalable, and secure confluence of systems and services that solve real-world user problems
By proactively surfacing and mitigating technical debt, security issues, and architectural risks, production incidents are consistently prevented
Less experienced engineers grow measurably in technical confidence and skill through mentoring and code reviews
The team works with a healthy, collaborative dynamic where trust enables a genuine sense of enjoyment and pride in building great software together
