Strong working knowledge of the full stack. * Proficient in technologies relevant to our stack (e.g.,Java, Node.js, PostgreSQL, MongoDB AWS or similar cloud providers). * Has scaled platforms operationally, not just designed them on paper.

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. * Experience at a consumer, social, or marketplace company is a plus - those are the users we build for. ## Description At Posh, you'll set the technical direction for our backend systems. As Staff Backend Engineer, you own architecture across multiple services, drive platform improvements, and ship production code yourself., * Own backend architecture across multiple services and team boundaries, from design through implementation. * Write production code daily and set the standard on quality, reliability, and engineering practice. * Partner with engineering leads and product managers to scope large initiatives and define what "done" actually means. * Improve scalability, performance, and reliability as the platform grows. * Identify and clear technical debt across teams, not only within your immediate scope. * 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. * Help us hire well - participate in technical interviews and calibration. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [40 Minutes to Build a Serverless COVID-19 REST and GraphQL APIs](https://www.wearedevelopers.com/videos/208-40-minutes-to-build-a-serverless-covid-19-rest-and-graphql-apis) - [Stop using Node.js like in 2020!
