Why This Job is Featured on The SaaS Jobs
This Senior Software Engineer role sits at a particularly SaaS-native intersection: merchant onboarding, configuration, and the internal tooling that supports revenue operations. In an AI-native finance platform, onboarding is not just a setup flow, it is where product constraints, data integrity, and customer trust converge, and where platform decisions quickly surface across billing, collections, and reporting.
From a SaaS career standpoint, the scope signals strong exposure to end-to-end systems thinking. Work that spans APIs, product surfaces, and complex data flows tends to build durable skills in reliability, observability, and operational maturity, especially when the same team owns both customer-facing experiences and the tools used internally to deliver and support the service.
The role is a good match for engineers who prefer clear ownership and are comfortable making tradeoffs across product, data modeling, and system design. It should appeal to senior builders who like partnering closely with Product and Design, can navigate ambiguous problem spaces, and want their technical decisions to influence how a SaaS platform scales in real production conditions.

Job Description
Tabs is the leading AI-native revenue platform for modern finance and accounting teams. Tabs agents automate the entire contract-to-cash lifecycle, including billing, collections, revenue recognition, and reporting, to help teams eliminate manual work and accelerate cash flow.
High-growth companies like Cursor and Statsig rely on Tabs to generate invoices directly from contracts, reconcile payments in real time, and automate ASC 606 compliance.
Founded in 2023, Tabs has raised over $91 million from Lightspeed Venture Partners, General Catalyst, and Primary. The team is headquartered in New York and brings deep expertise in finance and AI.
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.
Experience
5-8 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!
