Lead FinTech Engineer: AI-Driven Platform & Team Leadership

Leap; United States; On-site; USD 180,000 - 240,000; Full time

Job summary

Leap seeks an accomplished engineering lead to own the FinTech stack—from lender integrations to the new platform. You will balance hands-on coding with architecture and team mentorship.

You will drive integration with financial APIs, ensure audit trails and compliance, and ship features for autonomous agents. This role requires deep TS full-stack capability, proven leadership, and comfort in regulated fintech environments, with US Eastern hours.

Qualifications

• 8+ years of professional software engineering experience, with at least 3 at senior or above.
• You have led engineers while still shipping: design review, sprint planning, code review, honest feedback, and production code in the same week.
• Full-stack depth in TypeScript: deep on Node and PostgreSQL or on React, and competent in both.
• You have built systems that integrate third-party financial APIs with complex asynchronous flows: applications, decisioning, webhooks, stipulations, and disbursement.
• You have learned an unfamiliar, under-documented codebase fast and explained it back to others; this is the first thing you will do here.
• You have owned production systems end to end: on-call, post-mortems, and the trade-offs you can defend.
• You have been accountable for work you do not line-manage: partner teams, contractors, or other squads.
• You are comfortable in regulated environments: you understand why audit trails, retention rules, and versioned records matter, and you do not cut corners on them.
• AI is central to how you ship, and you already work at a high level of autonomy with it: you hand whole tasks to agents, run several at once (parallel sessions and worktrees, not one branch at a time), and build the tooling that makes them effective. This is a hard requirement, and we will ask you to show us how you work, live.
• Authorized to work in the US and able to keep Eastern time zone hours.

Responsibilities

• Lead the FinTech engineering team: planning, technical design review, code review standards, mentorship, and interviewing as the team grows
• Write production code in critical-path systems; roughly 70% of your time is hands-on
• Ship with agents, not around them: delegate whole features to autonomous agents, run several in parallel, and own the spec, the review, and the bar for everything they produce
• Bring the FinTech team and the partner team to the same way of working: the skills architecture, MCP tools, specs, and guardrails that let agents ship safely, and the standard for where to trust them and where a human stays in the loop
• Codify context and patterns so both engineers and agents move faster, and keep raising the ceiling of what can be delegated
• Build a working command of the lending and payment services in Leap SalesPro and Leap CRM, improve them, and document them so the knowledge does not live in one person
• Set technical direction for the partner team’s work on the new platform and hold the bar through standards, review, and early escalation rather than org-chart authority
• Own major domains of the new platform end to end: data model, API surface, service boundaries, and production operation
• Own the integration seam between the new platform and Leap’s products: API contracts, event boundaries, the migration path off legacy implementations, and consolidation of duplicated payment code into shared services
• Handle money and sensitive data with rigor: integer-cents arithmetic, idempotency, reconciliation, immutable audit trails, KYC and KYB, and PII
• Keep Eastern hours; the engineers you lead are in India and daily overlap is part of the job
