About the Role

Tabs is seeking a senior software engineer to join our Merchant Onboarding team. We're building 0→1 and we'll be defining ways to streamline the onboarding experience, unlock growth, and amplify our internal teams to move quickly. This team owns the full merchant journey, from onboarding & configuration to the internal tooling that powers our teams. Our engineers work across real production systems, complex data flows, and product surfaces used by teams who need software they can trust. We hire people who enjoy taking ownership, learning fast, and partnering closely with teammates to build things the right way.

Why Engineers Love Working Here

Our teams solve problems that don't have clear answers. The work spans new product development, system design, data modeling, and operational scale. Engineers join Tabs because they want to own meaningful systems, shape how our platform evolves, and learn from talented peers in a fast-moving environment.

At Tabs you will not be pushing anonymous tickets. You will be trusted with real scope, real decisions, and real customers. We expect engineers to think critically, debate ideas, explain tradeoffs, and follow through.

What You'll Work On

• Core backend services and APIs
• Product surfaces that finance teams rely on daily
• Interfaces and tools that simplify complex concepts for internal and external users
• Internal systems that improve reliability, observability, and performance

Across the company, engineers partner closely with Product and Design. Quick conversations, whiteboard sessions, and collaborative problem solving are part of our daily rhythm.

What We Care About

You'll thrive at Tabs if you:

• Enjoy owning systems end-to-end, from first design doc to fixing production edge cases weeks later
• Care deeply about correctness and long-term maintainability
• Are curious about domains you don't already understand, and are willing to sit with discomfort while you learn
• Can disagree respectfully, explain your reasoning, and change your mind when the data says you should

We're optimizing for excellent engineers who are good teammates.

What we don't care about as much:

• Exact years of experience
• Whether you're "frontend" or "backend" by title
• Whether you've worked in fintech before

If you've built scalable systems, shipped real software, and learned from breaking prod a time or two, we want to talk.

The Stack

We care more about how fast you learn than experience with our exact stack.

• TypeScript, Node, NestJS
• React, Next.js
• Postgres
• Redis
• Temporal for job management

Experience

• 3-5 years of professional software engineering experience
• Experience building web applications or backend services in production
• Familiarity with modern backend languages and frameworks
• Experience with modern frontend frameworks such as React, Vue, or similar
• Experience working with APIs and relational databases

If you want to build real systems with people who care deeply about their craft, we would love to hear from you. Engineers who thrive here like hard problems, clear ownership, and strong teams. If that sounds like you, apply!
