Software Engineer — Chicago, IL

About Stock

Stock is a B2B marketplace that moves surplus inventory from companies to nonprofits that can use it. We run the whole donation lifecycle: listing, matching, freight and the paperwork that makes it count. Donors clear space and get a tax receipt. Nonprofits get goods they would otherwise buy. Nothing goes to landfill.

We launched to real customers in October 2026. XCh platform was built end to end by one engineer. You would be the second.

XCh role

Full stack, no lanes: Elixir and Phoenix on the backend, Next.js and TypeScript on the frontend, Kubernetes and Terraform underneath. You scope a feature with the founders, build it, ship it, watch it in production and fix it when it breaks.

We are open on level, from early-career engineers who have shipped real software to senior engineers who want to build rather than manage. Title, scope and compensation match the person we hire.

Who we're looking for

• You have shipped and run a production web app, including the part after launch

• You are comfortable across backend, frontend and infrastructure, and strong in at least one

• You have worked in a typed or functional language and can pick up Elixir. Prior Elixir is a plus, not a requirement

• You have integrated with third-party APIs that misbehave and designed around it

• You can turn a vague business problem into scoped, shipped software

• You write clearly; most of our design discussion happens in writing

Early in your career? Show us something you built and ran yourself. That counts for more than a resume.

How we work

2 days on site in River North Chicago. Small team, direct access to the founders, a weekly roadmap review. We ship small and often, write decisions down, and use AI coding agents heavily. XCh work keeps real goods out of landfills and in the hands of nonprofits.

Compensation

• Salary: $120,000–$140,000, set by level

• Meaningful early-employee equity

• Health, dental and vision; flexible PTO; closed between Christmas and New Year's

• Your choice of machine and tools
