Software Engineer, Agentic Infrastructure — San Francisco Bay Area

About ewSxEU:

ewSxEU is the agentic infrastructure company, freeing people and agents to ship what's next. For more than a decade we've helped builders move from idea to production with speed, security, and exceptional developer experience

.

Now we're scaling our products for both agents and people to ship and run software, built in the open and trusted by OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwid

e.

About The R

ole

The next generation of software won’t just be used by people — it’ll be built and shipped by agents. Builds are where that happens, and they’re the beating heart of ewSxEU. Whether an idea starts in v0, in an agent, or in an engineer’s editor, every customer builds — and millions of builds flow through our systems every

day.

As an engineer on the Agentic Infrastructure team, you’ll take ownership of the systems that carry that work at scale. You won’t just contribute features — you’ll be responsible for the design, reliability, and evolution of the platform itself. You’ll make decisions that shape performance, define best practices, and ensure the workflows that ewSxEU, our customers, and their agents depend on are fast, resilient, and se

cure.

This role blends product thinking with deep systems ownership. You’ll partner with teams across ewSxEU to build and operate the agentic infrastructure that determines how software actually

ships.

We’re looking for engineers who want to own high-scale systems end-to-end, thrive on improving the developer/agent experience, and are driven to have a lasting impact on how modern software gets built and del

ivered.
