Why This Job is Featured on The SaaS Jobs
This Senior Backend Software Engineer role stands out in the SaaS ecosystem because it sits close to a high‑volume, API and partner driven product surface, where reliability and platform design directly shape the customer experience. The listing signals a company operating at meaningful transaction scale and extending a core account product into additional services, a common pattern for SaaS businesses expanding from a single use case into a broader platform.
For a long-term SaaS career, the work maps to durable backend themes: evolving architectures as product scope grows, building for observability and testing as first-class concerns, and balancing speed with robustness as usage increases. Experience designing systems that serve both customer-facing features and internal business functions translates well across SaaS companies that rely on shared services, clear interfaces, and operational discipline.
This position is best suited to an engineer who enjoys owning systems end to end, making pragmatic tradeoffs, and collaborating tightly with product and design rather than operating in a purely ticket-driven model. It also fits someone who wants to influence engineering patterns and planning, and who is comfortable working on a core, mission-critical backend where correctness and uptime matter as much as feature delivery.

About the Role
As a backend engineer, you’ll be responsible for extending our systems to support additional banking features, increases in usage volume, and the needs of our non-technical company functions.
You’ll maintain our core offering — a deposit account and debit card powered through our Banking as a Service partner, while designing our architecture to bundle additional financial services into a personalized product experience. We’ve adopted a lightweight microservice infrastructure that allows us to move quickly, but that can flex on robustness to ensure scalability as our engineering team grows.
What you’ll do
Collaborate with our product, design, and front end functions to build new financial offerings that advance the company mission.
Work with back end peers to establish new processes, software patterns, and tools that expedite our development process.
Maintain a testing and observability stack that keeps our system stable and proactively alerts us of internal or third party users.
Work with leadership to plan our engineering execution across different time horizons.
You are
Opinionated on software engineering best practices, at a code and developer productivity level.

A great communicator and collaborator, capable of creating and running cross-functional processes.
Requirements
4+ years of experience in software engineering
2+ years of experience using Python and Postgres
Bonus: Experience with GraphQL, DevOps (Terraform, AWS, Kubernetes), and pub/sub models (Kafka)
We value domain experts that are obsessed with their craft and push the quality bar beyond reach. We also like generalists that are self-driven and entrepreneurial, who can make product decisions and own operational processes.
Team
We are a team of 40 based out of New York, coming from industry-leading companies like Brex, Nubank, Cruise, and Verkada. Over half of us are immigrants, and have experienced the problems we’re solving first hand. We value customer focus, high ambition, principled decision-making, and deep trust.
