Job Description:

???? Senior Backend Engineer Build the Decision Engine Powering Modern Finance ???? Bay Area (Hybrid) | NYC considered ???? Up to $250K base + equity ???? Visa sponsorship available ???? Rebuilding Finance From First Principles A high-growth, VC-backed fintech is re-engineering the $13T U.S. mortgage market, not by improving legacy systems, but by replacing them entirely . They're building a vertically integrated platform that automates: Credit Underwriting Compliance Capital flows The result? Complex, manual processes transformed into deterministic, scalable software systems . Already in production and used by lenders, banks, and fintech's, this platform powers real financial decisions at scale . ???? Why This Role Stands Out You'll be building core financial infrastructure where: Precision matters Edge cases are the product Mistakes have real-world consequences You'll encode complex financial logic into systems that make high-stakes, automated decisions every day. ????? What You'll Be Responsible For Translating dense, rule-heavy domain logic into elegant backend systems Designing and implementing decisioning engines and underwriting infrastructure Building and evolving DSLs (Domain-Specific Languages) to encode financial rules Working closely with domain experts to capture nuance, exceptions, and edge cases Designing for correctness, observability, and failure resilience Applying AI within real production workflows (not experiments) ? What They're Looking For Core Requirements 3+ years backend engineering experience (mid-senior level) Strong TypeScript and backend systems design experience Proven ability to build production-grade, reliable systems Experience working with complex business logic or rule-heavy domains Comfortable collaborating with non-technical stakeholders ???? Strong Signals (Highly Valued) Background in FinTech , payments, or regulated systems Experience at a VC-backed Start-up or as a founding engineer Exposure to high-performance environments (top tech / big tech also valued) Experience designing or working with DSLs for rule encoding (major plus) Familiarity with rule engines, workflow orchestration, or decision systems Exposure to AI / agent-driven systems in production ???? The Kind of Engineer Who Thrives Here You enjoy turning messy real-world problems into structured systems You think in edge cases, constraints, and failure modes You prefer ownership over tickets You're comfortable operating in ambiguity and moving quickly You've worked in environments where impact > process ???? The Environment Lean, high-calibre engineering team Multiple complex backend problem spaces (core logic, APIs, integrations) Hybrid model (2-3 days in-office, flexibility for top candidates) Fast iteration, high ownership, low bureaucracy The reality: You build it ? you own it Good ideas ship quickly The problems are genuinely hard ???? Compensation & Benefits ???? $150K-$250K base (flexible for exceptional candidates) ???? Meaningful equity ???? Visa sponsorship available (including new H-1B applications) ???? Probably Not a Fit If You prefer low-impact or maintenance-heavy work You've mainly worked in slow-moving, legacy environments You want fully defined tickets instead of open-ended problems ???? The Bottom Line This is a rare chance to: Build core financial infrastructure from the ground up Work on systems where every decision has real monetary impact Shape how complex financial rules are encoded, automated, and scaled Join a VC-backed fintech at a stage where architecture still matters ???? Ready to Build Systems That Actually Decide Things? If you've operated in fintech, high-growth start-ups, or as a founding engineer , and you're excited by complex backend systems + DSL-driven logic , this is exactly the kind of challenge you've been looking for.
