Senior Software Engineer at Sofar Ocean (San Francisco, CA)Senior Software Engineer

You will be a key contributor to frontend and backend engineering on cloud software systems on the Spotter team, which is a highly cross-functional group that designs our sensing systems and the applications that connect them. You’ll work alongside other software engineers and collaborate directly with hardware and firmware engineers to build features in applications like spotter.sofarocean.com spotter.sofarocean.com and APIs (see docs.sofarocean.com docs.sofarocean.com) that interact with our hardware products: Spotter, Smart Mooring, next generation platforms, and Sofar’s open hardware connectivity stack Bristlemouth bristlemouth.org bristlemouth.org.

You thrive in small and collaborative multidisciplinary teams, and love learning something new and surprising every day. You strive for the shared success of improving the health of our oceans and planet by shipping a cohesive, performant and impactful product.

You’re a full-stack engineer with experience developing frontend and backend elements of modern web applications. Our tech stack includes React on the frontend with backend APIs written using Typescript, Express, and Postgres. You will own features across the stack and should be comfortable architecting solutions from the data storage layer to UIs.

This role will be working onsite at our Pier 28 office at least 3 days per week and reporting to our Senior Engineering Manager.

We had a particular user account with rapidly increasing numbers of deployed hydrophones, reporting data more and more frequently, with many users concurrently opening the dashboard that displays complex visualizations of this real-time streaming dynamic data, so that the load on the backend system was compounding exponentially. We’re proud of some intense, fun, and successful performance testing work we did, with solutions that spanned React component data invalidation, multiple layers of caching, database index optimization, and remotely configurable thresholds on the hardware systems.

We're currently automating some processes for configuring and updating a wide range of remote hardware devices in order to make it easier for users to manage their systems safely without contacting support. One part of the challenge is documenting the giant unwritten decision tree that has only ever been performed by our very smart and deeply knowledgeable colleagues. We all continue to surprise each other by bringing up yet another caveat or edge case that we have to account for in software.
