We're hiring a senior software engineer to be a technical anchor on the New York team — shaping architecture, mentoring engineers, and driving high-impact projects from ambiguity to production. The team currently has 7–8 FDEs transitioning into developers, most of whom have development backgrounds but are pretty junior. 

The need is one (potentially two or three) really solid senior devs who can provide oversight and mentorship, ship features themselves, and own the harder architectural problems that junior engineers + Claude/Opus aren't quite going to solve. Profile is a "cracked tech lead" not an engineering manager — strong individual contributor who can also review PRs of junior engineers and contribute as a senior team player by virtue of technical experience. The right person owns one of the more challenging flagship features as quickly as possible (e.g., agentic initiative that provides proactive suggestions to users on the homepage), gets to team lead level on a core product feature within 6 months. 

What You'll Own Technical Leadership

Own end-to-end design and implementation of complex, cross-cutting features — from task breakdown through delivery, monitoring, and long-term maintenance Set the technical bar: produce elegant, well-reasoned designs and high-quality code others can learn from and build on Drive architectural decisions and participate in design reviews, ensuring systems are scalable, maintainable, and aligned with long-term vision Mentor and level up junior and mid-level engineers through code review, pairing, and thoughtful technical feedback

Product Mindset

Collaborate directly with product and design to translate ambiguous specs into clear, well-scoped engineering plans Proactively identify opportunities to improve product quality, developer velocity, and business outcomes — not just execute on tickets Balance immediate business objectives against long-term architectural vision Champion the user experience from the engineering side

Reliability & Platform Health

Own the reliability of the systems you build: define SLOs, instrument observability, drive incident response and post-mortems Contribute to platform and infrastructure improvements — CI/CD pipelines, deployment tooling, production runbooks Champion engineering best practices around testing, observability, and on-call hygiene Lead capacity planning and performance work for critical services:
