Full-Stack Engineer
$115k - $145kK.E.E.P. Inc
Compensation $115-145K base. Plus equity in our company! Location Remote eligible, but ideally candidates are based in ET or CT time zones and can fly directly to Washington, DC. Our team and office is in Bethesda, MD and we work in person every Monday, Tuesday, and Thursday, so a DC area resident or someone willing to relocate is preferred. If you are remote, you will need to fly to DC approximately every month to work with our team in person. About Keep Company Keep Company is on a mission to make human connection an intentional, scalable asset in every workplace. As a venture–backed SaaS platform recognized by Techstars, Forbes, and SHRM, our patented talent platform delivers transformative relationship–based development experiences at leading professional services organizations. With our platform, talent leaders can launch, scale and measure innovative programs, including mentoring, coaching and ERGs, with little admin burden and maximum impact. We’re proud to support 20+ clients in professional services—with zero churn and multiple six–figure contracts. At a time when artificial intelligence is rapidly reshaping how we work, Keep Company is rebuilding the human layer of work, because we believe people are the most important asset that organizations can invest in to strengthen culture, retention, and performance in the moments that matter most. The Opportunity We’re hiring a full-stack Software Engineer to ship features, fix bugs, and grow into a senior IC on our team. You’ll work directly with our Lead Engineer and our VP of Product. You’ll write production code every day, own end-to-end delivery on real client features, and pair with senior engineers on the harder work. You’ll join a small team at a real inflection point: enterprise pilots running with named law firm clients, an AI–native engineering culture in active development, and a platform foundation being rebuilt from the data layer up. This role is for someone who wants to be in the middle of that—shipping, learning, leveling up—rather than coasting on what they already know. We’re leveling this role to the candidate—~3–5 years of professional experience is the target, and we’ll go up or down for the right person. What You’ll Own Ship features end-to-end, frontend to backend—clean code, good tests, peer–reviewed PRs. Own bug–fix work across the platform. Help us reduce defect escape rate quarter over quarter and build the muscle memory of catching issues before they ship. Build the testing and tooling foundation of the team—Playwright suites, CI checks, the small tooling that compounds. We just stood up automated end-to-end testing; you’ll be a key contributor to making it part of how we work. Pair with the Lead Engineer on harder architectural decisions and learn the stack at depth. Contribute to code review and raise the team’s bar through your own work. Required Experience ~5 years of professional software engineering experience, ideally at a B2B SaaS company. Less experience with the right signal is welcome too. Strong in our full–stack—TypeScript, React, Node—or able to demonstrate quick fluency in equivalent stacks. We don’t expect a 1:1 match; we expect you can ramp. You write tests as part of writing code, not as an afterthought. You can talk us through your most recent meaningful piece of code in detail—what you built, what was tricky, what you’d do differently now. You use AI tooling daily—Cursor, Claude, Copilot, or equivalent—and have a point of view on what they’re good for, where they fail, and how you verify output. You ask questions when you’re stuck and flag risks early rather than working around them. You close loops. When you own something, the next step is clear without anyone chasing you. Nice to Have Experience working in a small team where contractors and FTEs ship side by side. Exposure to multi–tenant SaaS, identity systems (WorkOS, Okta), or HRIS integrations (Workday, UKG). Experience in HR tech, legal tech, or future–of–work environments. Open–source contributions, side projects, or any signal that you build things outside of work assignments. How You Work You’re a generous reviewer and a strong pair partner. You take ownership of quality—not just your code, but the user experience your code creates. You’re hungry to learn but not afraid to push back when you disagree. You communicate directly—you ask the question rather than work around it. You have current code commits you’re proud of, and you can talk us through them. Why Keep Company A real inflection point—visible impact from day one, on a platform serving named enterprise clients. A genuine AI–native engineering culture, not a retrofitted one. Mentorship from a Principal–level Lead Engineer in a small, ship–focused team. A team that pairs, reviews, and ships together. Competitive salary, meaningful equity, medical/dental/vision, 401k, and flexible PTO. A mission–driven team building something we care about. About Our Stack Next.js application (React, TypeScript) with Aurora PostgreSQL on AWS. If you’re energized by our mission but don’t meet every listed qualification, we’d still love for you to apply. #J-18808-Ljbffr K.E.E.P. Inc
