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
