Senior Backend Software Engineer (NYC)

About Común

Comun’s mission is to help Hispanic immigrants turn their hard work into upward mobility — starting with financial services that support their transition from a cash-based system to the digital economy.

We offer checking accounts that can be opened using 100+ types of Latin American IDs, access to over 90K locations nationwide to deposit cash, international transfers to 17 countries at market-leading rates, and 24/7 bilingual customer support with <5 min SLA across email, chat, and phone.

We currently process over $1.5B in annual transaction volume and surpassed $100M in annualized international transfers just six months after launch. Comun has raised +$50M from top investors including Redpoint, Costanoa Ventures, and South Park Commons. Our team brings experience from leading fintech companies like Brex, Nubank, and Mercury.

We believe immigrants are the ultimate entrepreneurs — driven by relentless ambition and a vision for a better future for their families. Comun exists to serve them throughout their journey.

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.

• Product-minded and passionate about delivering delightful experiences to customers.

• Experienced building backend systems that grow in complexity over time.

• A critical thinker capable of making tradeoffs in a fast paced environment.

• 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.
