Rebuild a $13 Trillion Industry

HireQ Talent is working with a fast‑growing, well-funded fintech company rebuilding the U.S. mortgage industry from the ground up.

Rather than optimizing around legacy processes, the company is building a fully automated, vertically integrated platform covering credit, compliance, capital, and underwriting, replacing manual workflows with software.

Backed by tier‑1 investors and operators from leading fintech companies, the platform is already used by lenders, fintech's, and banks to power originations at scale.

The Role

We’re hiring Senior Backend Engineers (multiple hires) to design and own high‑stakes financial systems where correctness is critical.

You’ll be responsible for encoding complex, real‑world financial logic into production systems where precision, edge cases, and reliability directly impact business outcomes.

What You’ll Do

• Translate dense, rule heavy financial logic into scalable backend systems
• Build core underwriting and decisioning infrastructure using TypeScript, DSLs, and AI
• Work directly with subject matter experts to model nuance, exceptions, and edge cases
• Design systems for precision, observability, and failure handling
• Build internal tools that power automated decision‑making workflows
• Apply AI in real production environments, not prototypes

What We’re Looking For

• 3+ years backend engineering experience (mid → senior level)
• Strong experience with TypeScript and backend systems design
• Experience in fintech, payments, SaaS, or other regulated domains
• Background at a high‑growth startup, top tech company, or leading fintech
• Proven ability to translate complex business rules into production systems
• Comfortable working closely with non‑technical domain experts

Strong Signals

• Experience with DSLs, rule engines, or workflow orchestration

• Exposure to AI / agentic systems in production
• Background in high reliability or compliance‑heavy systems

The Environment

• Lean, high‑calibre engineering team scaling rapidly
• Multiple backend problem areas: core logic, APIs, integrations
• Hybrid setup (2-3 days/week in office) with some flexibility for strong candidates
• Culture of high ownership, low process, and rapid iteration

This is a team where:

• If something breaks, you fix it
• Good ideas get shipped quickly
• The problems are genuinely difficult

Compensation

• 💰 $150K–$250K base (flexible for exceptional candidates)
• 📈 Equity included
• 🌍 Visa sponsorship available (including new H‑1B applications)

Not For You If

• You prefer maintenance work or low impact systems
• Your background is primarily in slow‑moving legacy environments
• You want clearly defined tickets instead of ambiguous, high‑ownership problems

Why Join?

• Build infrastructure for a massive, underserved market
• Work on systems where every decision has real financial impact
• Apply AI to complex, real world workflows
• Join at a stage where core systems are still being defined
