Senior Full-Stack Engineer - Tech Lead (f/m/d)

REPLOID is a pioneer in circular bioeconomy: Through scalable upcycling solutions, organic residues are transformed into new valuable resources and marketable products directly at their source, for example, for the feed and fertilizer industry. We provide exemplary additional value and significantly contribute to meeting growing sustainability requirements (Scope 3, CO2 emissions...).

#wearereploid - We think long-term and set new standards. To further advance our mission, we are looking for you. Your work has a visible impact with us! If you are looking for more than "business as usual," want to take responsibility and shape decisions, you fit perfectly into our dedicated team!

Your Mission

In this key role as a Senior Full-Stack Engineer, you are responsible for our plant software and its ongoing optimization - as well as your personal development. You program robust services and integrations along clear architectural principles and gradually take over responsibility for the software architecture. With your focus on DevOps, strong ownership, and implementation strength, you actively manage the takeover/handover process, secure knowledge and responsibilities, and set engineering standards to increase reliability in operation and design a scalable, sustainably operable platform.

Your Tasks

• Design, implementation, and testing as well as operation of features and services (frontend & backend) with a strong hands-on focus and ownership for individual core modules

• Implementation of robust integrations via clearly defined APIs and contracts instead of tight system coupling

• Shaping the system architecture as well as further developing our engineering standards (baseline, guardrails) and the associated documentation

• Responsibility for technical quality through design and code reviews, design of release and operation processes, as well as creating short design documents/ADRs for critical architectural decisions

• Cross-functional contract layer function for telemetry data contract including common signal definition and test strategy for secure changes at the system boundaries

• Interface in the transition plan as well as active collaboration with internal and external engineers

What You Bring

• Completed studies in computer science/software engineering, position-relevant higher education, or comparable practical experience

• Several years of experience in the development of production-related systems as well as operation and observability in production

• Very good backend skills in Java as well as frontend expertise (React/Next.js) in full-stack practice

• Proven experience in CI/CD (GitHub Actions), review culture, and release processes

• Practical experience with cloud and container technologies (Docker, AWS, or equivalent) as well as their operation and monitoring, ideally with infrastructure-as-code approaches (e.g., Terraform)

• Communication skills in fluent English as well as pronounced abilities in interface and contract design

What We Offer

• Meaningful work in an innovative, sustainable company

• The opportunity to actively shape processes and take responsibility

• A dynamic, growing work environment with a lot of room for design

• Flat hierarchies, team spirit, and an open corporate culture

• Hybrid work and flexible working hours
