The posting

Lithic is the modern card issuing and processing platform empowering ambitious financial companies to build the future of payments.

Our infrastructure powers card programs for 100+ innovative clients, from fintechs reimagining credit and digital banking to platforms transforming disbursements and spend management. Companies like Mercury, Flex, and Novo rely on Lithic's developer-friendly APIs, direct network connections, and flawless reconciliation to launch and scale card programs in weeks, not years.

We're building a future where access to better financial products materially improves people's lives, free from the constraints of 30-year-old mainframes and legacy processors. We're proud to be backed by world-class investors who share that vision, including Bessemer Venture Partners, Index Ventures, Spark Capital, Stripes, and Mastercard, along with many others.

We're a team of 170+ across 26 states and 7 countries, headquartered in New York City.

We are hiring a Senior Software Engineer for Lithic’s Card Authorization team, which owns the real-time systems that make every card authorization decision correct, reliable, and fast. The team also owns related fraud tooling, including Lithic’s Rules Engine and 3D Secure integration. You’ll own high-impact projects end-to-end, solve distributed-systems problems at scale, and help build the tools customers use to control fraud and payment risk.

What you'll do:

  • Write reliable, secure, scalable code for Lithic’s real-time authorization and fraud-prevention systems with minimal tech debt
  • Build customer-facing features, such as rules improvements, velocity controls, 3DS flows, fraud tooling, and transaction monitoring. Own projects from planning to launch.
  • Improve the reliability of systems in team’s scope and participate in the team on-call rotation
  • Lead efforts to improve systems and processes within the team

What you'll bring:

  • 4+ years building production backend systems. Full stack experience is a plus.
  • Experience in or desire to learn Rust; ability to understand Lithic’s system written in other programming languages (Python, Java)
  • Interest and experience in leveraging AI tools to enhance productivity
  • Ability to navigate ambiguity, align diverse perspectives, and drive toward practical solutions
  • Experience or interest in payments, fintech, fraud prevention.
  • Comfort with designing systems from scratch and owning the product development process end-to-end
  • Strong written communication skills and experience working in a remote, async-first team that’s spread across time zones

The annual US salary range for this role is $160,000 to $200,000 plus equity. This salary range may be inclusive of several career levels at Lithic and will be narrowed during the interview process based on the candidate’s experience and qualifications.

This is a remote position. However, candidates must be located in the United States, Canada (Ontario or British Columbia), Netherlands, Poland, or Czech Republic. We do not offer visa sponsorship or assistance.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
