Summary ✨ AI‑Generated

A senior software engineering opportunity combining substantial hands-on backend development with technical leadership. You will help establish engineering standards, strengthen code review and documentation practices, mentor developers moving into PHP backend work, and collaborate on architecture and project direction. Strong production experience, backend expertise, technical mentorship skills, and German fluency at B2/C1 level are required, with prior lead experience considered an advantage.

Highlights

Hands-on senior engineering role with significant technical leadership responsibilities, opportunities to shape team standards and architecture, and a path toward a technical lead position. Includes mentoring and close collaboration on technical direction.

Description

We're hiring on behalf of a Haystack partner! The Role • Spend approximately 70% of your time on hands-on development in production code. • Dedicate the remaining time to team leadership, including code reviews, pairing, and unblocking team members. • Drive the establishment of team standards, processes, documentation, and a robust review culture. • Ensure predictable delivery and high-quality output within the team. • Support two developers transitioning to PHP backend development. • Collaborate closely with the CTO/Architect on architecture and project direction. What You'll Need • Several years of production experience with a strong senior developer background. • Proficient in at least one backend language, with a willingness to work with PHP. • Proven ability to lead technically through mentorship and example, rather than authority. • Desire to grow into a technical lead role; prior lead experience is a plus. • Fluency in German (B2/C1 level) is mandatory for team collaboration. • Experience with event-driven systems (Kafka/Redis Streams) and Linux/NixOS is beneficial. What's On Offer • Competitive salary. • Significant impact in a small, visible team where your standards shape development practices. • Opportunity to grow into a lead role, influencing team processes and quality. • Collaboration with a CTO/Architect and a diverse engineering team.
