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.
