Senior Software Engineer, Full-Stack

Role Description

Till is a banking platform built for families - debit cards, accounts, and tools that help parents raise financially capable kids. This is a rare chance to join a mission-driven fintech at a genuine inflection point. With the backing of Western & Southern Financial Group, we have the runway and resources to build ambitiously - while staying small, lean, and focused. You’ll have real ownership and real impact from day one.

• Own medium-to-large features from technical design through production - across backend services, APIs, and consumer-facing web and mobile surfaces.
• Lead technical design discussions and architecture reviews.
• Ship money movement and payments features that have to be correct the first time - and stay correct under load, across multiple banking partners and rails.
• Carry full production responsibility: on-call rotation, performance and cost work, and the testing rigor (unit, integration, contract) that financial software requires.
• Mentor other engineers in code review and design review.

Qualifications

• At least 5 years of production Go experience.
• Strong React + TypeScript on the web.
• Experience owning medium-to-large features end-to-end.
• Experience building in hexagonal, onion, or comparable layered architectures.
• A track record of partnering closely with product, design, and business stakeholders.

Requirements

• You’ve shipped and operated Go services.
• You’ve shipped a consumer mobile app to production (React Native or native).
• You’ve operated under the constraints of money movement before.

Benefits

• Base salary range: $150,000 - $200,000 USD, depending on experience and location.
• Annual bonus based on experience.
• Health, dental, and vision coverage.
• HSA with company contribution.
• Parental leave.
• Flexible time off.
• Remote-first - NYC preferred for occasional in-person collaboration.
