Internship R&D Software Engineer Jobs in Philadelphia, PA

Sharing Excess is a national food rescue nonprofit on a mission to end food insecurity by redirecting surplus food to communities that need it most. Since our founding, we've rescued over 200M lbs. of food through partnerships with grocery stores, wholesalers, farms, and over 1,200+ community hunger relief organizations across North America. Our work is powered by a lean, mission-driven team — and increasingly, by the technology we build to make food rescue faster, smarter, and more transparent.

Our tech team is the connective tissue of the organization — enabling every other team to do what they do faster, more accurately, and with greater impact. We're looking for a Software Engineer who wants to build tools that matter.

We’re looking to add a Software Engineer to our  small but mighty tech team,currently consisting of  our CTO, a Data Analyst,a Designer, and a team of part-time and volunteer contributors. You'll work shoulder-to-shoulder with our CTO to build and maintain the platforms that power our food rescue operations, and you'll have real ownership over the code you ship.

We're looking for an early-to-mid career engineer (1–4 years of professional experience) who brings the diligence of a skilled craftsperson to their work — someone who writes code they'd be proud for the next person to read, documents as they go, and treats quality assurance as part of the job. Think less "move fast and break things," more "build it right and explain why."
At SE, we know AI tooling has massively shifted the software engineering workflow - and we’re leaning in. We’re looking for a candidate who brings strong engineering principles and judgement to an AI assisted workflow, knowing when to move fast with agentic assistance, and how to build responsible guardrails for sustainable and maintainable software.
