Senior Backend Engineer - Grant Growth Team

Location: San Francisco

Department: Engineering

Senior Software Engineer (Backend) - Grant Growth Team

On Grant, we’re helping with the single most painful, important, and urgent problem of consumer finance - short term liquidity needs. IE, how do you pay for gas to get to your job, pay for unexpected emergencies, make ends meet with groceries before your next paycheck lands. We solve this real world pain point by providing fast, fair access to earned wages- without the predatory fees common in the industry. Our business model is profitable while maintaining customer-first values, and we're experiencing rapid user growth as we scale our impact.

Grant has recently launched to the general public at the very start of 2025 and has since scaled from thousands to hundreds of thousands of active subscribers and on track to disburse and recollect its first billion dollars. Looking toward 2026 we expect to continue scaling up towards billions of dollars per year disbursed to a million plus active subscribers.

We are looking for a Senior Software Engineer to join the Grant Growth team who is excited to build net new zero to one product experiences and scale existing offerings to the level to support our next phase of hyper growth! You’ll be working on critical features / offerings that bring users coming back and continually find more value in Grant.

What You’ll Be Doing

• Design and implement core backend systems for supporting growth features that hundreds of thousands of users use weekly - scaling to handle millions monthly.

• Level up product experience throughout the user lifecycle. From onboarding to advancing to account closure. You’ll own and iterate on these experience

• Integrate with third-party financial service providers and internal services, building robust APIs and data pipelines that ensure accuracy and consistency at scale - scaling up to billions of dollars per year

• Experiment and iterate on new user offerings and existing experience to improve retention and user value.

• Contribute across the stack on user-facing experiences tied to core subscription payments and related features — from checkout and repayment flows to account management.

• Enhance observability and reliability, introducing monitoring, alerting, and fault tolerance into user-critical systems.

• Support adjacent product areas, contributing to shared systems and features beyond grant as part of a cross-functional engineering org.

You'll work closely with our product, data science, and operations teams to ship features that directly impact our customers' financial wellbeing while maintaining the highest standards of reliability and security.

What We’re Looking For

• 5+ years of experience with modern backend frameworks and a track record of building and scaling production systems

• Production experience with background job processing systems (Sidekiq, Resque, or similar)

• Solid understanding of database optimization, caching strategies, and performance tuning

Ideal Candidate Also Has

• Experience with payment systems, financial infrastructure, or regulated environments (ACH, card processing, real-time payments)

• Background in fintech, payments, or lending infrastructure

• Technical Leadership: Ability to own complex technical initiatives end-to-end, from design through implementation and rollout

• Mentorship: Help level up the team through code reviews, design docs, and technical guidance

• Impact Focus: Balance technical perfection with pragmatic delivery - you know when to build for scale vs. ship fast

• Cross-functional Collaboration: Partner effectively with product, data science,and operations to deliver customer value

• Operational Excellence: Take ownership of the reliability and performance of the systems you build

What Makes this Role Exciting

• We’re scaling hyperfast! Lots of scope and growing team.

• Your work directly improves the financial lives of real customers. Not nice to haves, but life changing user value propositions

• Greenfield opportunities to architect new systems alongside legacy modernization challenges

• Small, high-impact team where your contributions are immediately visible

• Solve interesting technical problems at the intersection of payments, transactional data, and user retention
