• Break down product requirements and roadmap objectives into clear technical milestones.
• Mentor engineers and help resolve technical challenges and blockers.
• Work closely with Product and Design teams to translate business requirements into technical solutions.
• Coordinate technical dependencies across different engineering areas.
• Evaluate technical trade-offs and communicate risks, constraints, and recommendations clearly.
• Take ownership of technical delivery and ensure alignment between product requirements and implementation.
• Strengthen security across authentication, authorization, API boundaries, token flows, and application configuration.
• Help evolve the platform from MVP-level infrastructure toward a scalable production architecture.
• Define and improve testing strategies for critical product workflows.
• Establish practices that improve system reliability, observability, and release confidence.

What you bring

• 6+ years of software engineering experience, with previous experience as a Technical Lead, Staff Engineer, or in a similar technical ownership role.
