About the role

At Posh, you'll set the technical direction for our backend systems.
And you stay close to the work - implementation matters as much as architecture at this level.
This is an in-person role at our New York City office in SoHo.

Own backend architecture across multiple services and team boundaries, from design through implementation.
Partner with engineering leads and product managers to scope large initiatives and define what "done" actually means.
Build security and observability into systems from day one rather than bolting them on later.
Build with data in mind: instrumentation, pipelines, and tooling that surface meaningful insight for organizers and the business.
Mentor engineers across levels and shape technical culture through reviews, design discussions, and direct coaching.
8+ years of backend engineering experience, including time as a Staff, Principal, or technical lead.
Has designed and delivered systems that span multiple services or teams with clear ownership of the outcome.
Has scaled platforms operationally, not just designed them on paper. You've watched performance regress under load, run incidents, and evolved architecture that was already in production.
Posh enables anyone to build an IRL community based on shared interests, while connecting consumers with the communities of people just like them.

Proficient in technologies relevant to our stack (e.g.,Java, Node.js, PostgreSQL, MongoDB AWS or similar cloud providers).
You've watched performance regress under load, run incidents, and evolved architecture that was already in production.
Pragmatic about technology choices.
You pick the right tool for the problem and can defend the tradeoff.
Communicates technical tradeoffs clearly to engineers, product, and business leaders.
Mentors and raises the engineering bar for the people around them.
