About Taxwire
Taxwire is solving a forever problem. Anthropic might eat half the SaaS companies. AI could automate jobs. They might even cure death. But taxes are forever.
We’re tackling one of the largest markets in the world. → Indirect taxes (sales tax, VAT, etc.) are one of the most complex and least sexy forms of taxes in the world. Today, businesses globally remit $600B+ in sales tax and ~$5 trillion in VAT every year. The average $50-100M business will manage sales tax filings across 40+ US states and 20-30 countries. The problem space is deeply complex and ripe for automation and better products.
Our customers trust us to fully manage their tax compliance. → Most finance, accounting, and tax teams are not experts in sales tax. They also have 12 other responsibilities to manage, that don’t include thinking about indirect tax compliance. Taxwire exists to be their trusted partner in managing their compliance from end to end.
What we’re building to serve our customers. → To achieve this, we’re rebuilding a global tax platform from the ground up: the data layer, the tax calculation engine, the filing infrastructure, tax remittance, customer dashboards, accounting + billing workflows, and AI-powered the services that surround it.
Our team has deep industry expertise + startup experience → Our engineering, product, tax team’s built the tax products at Stripe, TaxJar, and Avalara prior. Others started VC-backed companies prior to joining. Others helped scale other startups in the Office of the CFO. Everyone’s here to win and build something that endures.
Where we’re at today → Recently raised our Series A, have hundreds of customers across SMB and mid-market, and are growing fast. 50%+ of our customers are ripping out legacy incumbents to switch to us. We serve customers in tech, but also in non-tech industries like construction and manufacturing.
Our customers → We serve finance, accounting, and tax teams. Some of our customers you’d know like Omni, Pulley, Modal, Spellbook, and Middesk. Others you wouldn’t because they’re far outside Silicon Valley or tech (e.g. construction and manufacturing). To date, we’re very proud to have had 0 churn.
Our investors → We’ve raised ~$25M from Headline, XYZ Ventures, Vinyl, Recall Capital, J Ventures, Nomo Ventures, Siqi Chen, Michael Bock, Justin Mares, Mike Rosengarten (OpenGov co-founder), Erik Torenberg, and dozens of other operators, CFOs, and accountants.
The role
We’re looking for a skilled, experienced, and motivated Backend Engineer to join our team. This role is focused on backend infrastructure, systems architecture, and core product logic. Frontend experience is a plus, but not required.
You’ll work closely with our founders, engineers, and tax SMEs to architect and build the foundational systems that power Taxwire - from our data model and automation pipelines to real-time tax calculation and compliance logic. You’ll play a key role in defining the internal platform that enables our team to ship faster, automate more, and scale globally.
This is a great role for someone who thrives on complexity and wants to help build something important from the ground up. If you’ve ever nerded out over how Stripe, Rippling, or Modern Treasury abstract complicated domains, this is that kind of role.
Key responsibilities
Design and implement core backend services - including data modeling, compliance logic, and internal platforms that support tax automation at scale.
Build scalable systems to monitor, calculate, and apply transaction taxes across a wide range of jurisdictions and industries.
Develop and maintain our domain model for tax rules, jurisdictions, thresholds, and impositions.
Build automation pipelines for filings, payments, and customer workflows.
Use browser automation, scripting, and task queues to reduce manual work across compliance processes.
Leverage LLMs and programmatic tools to enhance tax research, rule extraction, and error handling.
Collaborate across engineering, tax, and product teams to turn complex policy into scalable software systems.
Things we’re looking for
5–10+ years of professional software engineering experience, with a strong focus on backend development.
Strong experience designing systems, services, and data models in complex domains.
Proficiency in our backend stack: Python (FastAPI, Pydantic, pandas, duckdb), Postgres, SQL. Infra runs on AWS.
Bonus: experience working on automation-heavy systems, developer tools, or regulated workflows.
Bonus: experience with LLMs, scripting, or browser automation tools like Playwright.
High attention to detail. Our credibility with customers depends on accuracy and correctness.
Strong communication skills. We’re a writing-first company, and clarity is key in cross-functional work.
A self-starter who can lead projects, make architectural calls, and execute independently.
You’re known for shipping a lot of high-quality code, fast - and taking ownership end-to-end.
Why you shouldn’t work with us
You love lots of structure and want to be closely managed.
You are not ready to put in the hard work of taking something from 0-1 and then 1 to 10.
You’re not excited by complex domains or mission-critical systems.
Don’t get excited about serving our customers or find this problem space boring.
You hate the idea of talking to a customer.
You lack taste.
Shipping lots of high-quality code, fast… scares you.
Automate compliance across your finance and commerce stack. Easy implementation from our tax experts and engineers. Save time, money, and headache on sales tax.
