Senior Full Stack Engineer

About Us
Propel builds technology that strengthens the social safety net in America. We envision a future where every American has the tools and resources they need to thrive.
The safety net’s strength depends not just on funding, but delivery. Propel exists to dramatically improve how government benefits are delivered. Managing SNAP benefits, picking a D-SNP plan, or protecting against EBT theft should feel as seamless as Apple Pay or Netflix.
Governments struggle to build modern, scalable user experiences. We don’t.
Over 5.5 million Americans trust Propel today. We’ve grown revenue 35% YoY and are reinventing entire benefit categories, including Medicare, around the real needs of low-income Americans. We’re building a high-growth, high-ceiling, sustainable for-profit company where impact drives revenue.

About the Role
We’re hiring a Senior Fullstack Engineer who wants to build consumer products at meaningful scale with real ownership.
This is not a ticket-taking role. You’ll work across mobile apps, backend systems, internal tools, and new product lines. You’ll help identify problems, shape solutions, and ship iteratively in a space shaped by policy changes, evolving technology, and real-world constraints.
The technology landscape is evolving quickly, including the growing role of AI in how products are built and how users interact with technology. We don’t adopt trends blindly, but we do expect engineers to stay curious, experiment thoughtfully, and continuously evolve their craft as the world changes.
We are not meeting-heavy. Engineers have meaningful heads-down time. Product, Design, and Engineering operate with shared values, curious, empathetic, user-first, which reduces friction and accelerates execution.
Comfort with ambiguity, strong product instincts, and a bias toward action are essential.

That work requires strong partnerships and comes with unique challenges.
We operate lean, and priorities can shift as policy, partners, or user needs evolve. Our environment isn’t highly structured with rigid swimlanes or long, predictable planning cycles.
Engineers move across product surfaces and problem spaces. This isn’t a narrowly
