lemfi - Senior Software Engineer - Foundations

• At least five years of backend engineering experience with Go as your primary language in a production environment. • A track record of building and scaling distributed systems - you have seen things break at scale and know how to design so they do not. • Experience working on or closely with platform or enablement teams: shared libraries, internal tooling, developer experience or API gateways. • Comfortable with the full lifecycle - design, build, operate, improve - with evidence of genuine end-to-end ownership rather than handing off to other teams. • Practical, demonstrable use of AI development tools in your daily engineering workflow; you validate AI output rather than blindly accepting it. • Strong opinions about system design, API contracts and service boundaries, backed by real examples you can walk us through. • Exposure to fintech, payments or identity/KYC systems. • Experience building SDKs or developer-facing platform services consumed by other engineering teams. • Prior work in a high-growth startup or scale-up (roughly 50-500 people) where you had to set standards, not just follow them.
