• Join Keep as Fullstack Engineer on the Cards team, where you’ll accelerate the execution of high-impact initiatives and play a key role in moving the Cards roadmap forward with speed and ownership. • As a Fullstack Engineer at Keep, you’ll ship features end-to-end, work across our TypeScript/NextJS/GraphQL stack, and collaborate with a fast-paced, high-autonomy team. • You’ll bring strong fundamentals, clear technical thinking, and the ability to balance speed with correctness in the products you build. • Ship high-quality features end-to-end across the Cards domain. • Experience shipping user-facing features with real business impact. • Take ownership of technical decisions, tradeoffs, and execution. • Prioritize effectively and balance speed with correctness in your implementations. • Break down ambiguous problems into clear, actionable work. • Communicate clearly with technical and non-technical collaborators. • Participate in design discussions, bringing critical thinking and product awareness. • Ensure smooth collaboration during handoffs and across engineering efforts. • Maintain and improve the reliability, performance, and scalability of the Cards systems. • Apply strong fundamentals in architecture, clean coding practices, and database design. • Troubleshoot, debug, and optimize features with attention to detail.

• Design and ship features across the stack (frontend + backend) to deliver high-impact functionality quickly. • Build integrations and workflows, developing APIs, data flows, and partner integrations that extend our client's ecosystem. • Balance scrappy with scalable, leveraging no or low-code solutions where they accelerate delivery and investing in solid architecture where it matters most. • Participate in code reviews, pair programming, and collaborative problem-solving. • Help improve engineering processes and documentation as the team and product evolve. • Prepare for growth by ensuring systems and processes meet investor diligence standards as the company approaches Series A.

• Own the technical strategy and architecture of our IAM platform • Design and evolve OAuth 2.0 / OIDC flows and token lifecycle • Drive decisions on protocol design, data modeling, and platform reliability • Identify systemic risks and performance bottlenecks • Define engineering standards, review critical code and designs • Collaborate with product, security, and infra teams

• Own the technical strategy and architecture of our IAM platform, covering authentication, authorization, and session management at scale. • Design and evolve our OAuth 2.0 / OIDC flows, token lifecycle, and security primitives to meet both product and compliance requirements. • Drive decisions on protocol design, data modeling, and platform reliability, and build buy-in across engineering and security teams. • Identify systemic risks and performance bottlenecks; lead initiatives to resolve them before they become incidents. • Define engineering standards, review critical code and designs, and create leverage for the team through documentation, tooling, and mentorship. • Collaborate with product, security, and infra teams to align on roadmap and translate business needs into well-scoped technical plans. • Serve as the go-to escalation point for complex production issues in the IAM domain.
