Senior Software Engineer, Financial Sync

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 looking for a Senior Software Engineer to join the Financial Sync team building a scalable, resilient platform for both the internal engineering teams and external ERP partners. You’ll be building a future, in which any Tabs engineering team can add new business entities with complex logic, and the data will arrive at the merchant’s ERP / GL system reliably.

Why Engineers Love Working Here

Our teams build iteratively — engineers work closely with product and design to deliver the first version that solves the problem, get it in front of the customers, and then use the feedback to build even better. We keep the bigger picture in mind but don’t let “perfect” get in the way of “useful”. 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 Do

• Build out the next generation of Financial Sync ERP platform, so that new vendors can build their own integrations within our platform.

• Ship new features that will unblock new customers adopting Tabs for herding their companies’ increasingly complex financial flows.

• Enhance the usage-to-billing pipeline: ingesting raw usage events, aggregating them, turning datapoints into dynamic pricing.

• Work across the full stack — front-end configuration surfaces like an in-app workflow builder, as well as backend and event ingest infrastructure.

• Level up the engineers around you. The engineering organization has a range of experiences and backgrounds, and we’re growing fast. You'll be someone people look up to as you set the technical bar, mentor and learn from those around you, and shape the kind of culture we want as we get bigger.
  

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, but don’t let that stop you from shipping a useful initial version and learning from it.

• Practice systems thinking: spot the pattern across several different issues, talk to people to understand the true requirements, and see the common architectural solution instead of coding band-aid fixes.

• Are comfortable navigating startup uncertainty - we are building the future, so you need to be both opinionated and flexible about what that future ought to be.

• Are curious about domains you don't already understand - like accounting!

• Can disagree respectfully, explain your reasoning, and change your mind when the data says you should.
  

The Stack

We care more about how fast you learn than whether you worked with our exact stack, but here are some technologies we work with:

• TypeScript, Node, NestJS

• React, Next.js

• Java / Kafka

• Postgres, Redis, ClickHouse
  

Experience

• 5+ years of professional software engineering experience.

• Experience with TypeScript or a similar language, and a willingness to work across the stack.

• Understanding of best practices in querying relational databases.

• Experience with high volume data ingest a plus.

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