Summary ✨ AI‑Generated

A senior backend-oriented engineering role combining hands-on production development with technical team leadership. You will spend most of your time coding while also conducting reviews, pairing with colleagues, establishing engineering standards, mentoring developers, and collaborating on architecture. German proficiency at B2/C1 level is mandatory, and willingness to work with PHP is expected.

Highlights

A strong blend of hands-on engineering and technical leadership, with significant influence over development standards, architecture, delivery quality, mentoring, and team growth. The position provides a path toward a technical lead role.

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.
