At Numeric, we’re building the modern data platform for accounting and finance.
We’re building the financial platform that realizes the dream of live, rich, trustworthy data and insights for companies to drive decision-making & execution.
Among our hundreds of customers are Anthropic, Notion, Brex, OpenAI, Cursor, Plaid, Wealthfront, Mercury, Figma, and Asana.
We raised a $51M Series B in late 2025. We’re backed by IVP, Menlo Ventures, Founders Fund, 8VC, et all. as well as founders and executives from Ramp, Segment, and more.
Why Numeric?
Accounting is a massive, growing data problem. Every business would like to ground their decisions, strategy, and analysis in rich, up-to-date information. Financial data, however, is poor, fragmented, delayed, and lacking context; the accounting work to bring it together is tedious and error-prone. To fix this requires foundational changes in accounting and in the broader finance function.
We are addressing these problems at their root by building the infrastructure and product experiences to ingest events, transform them, match value movement, project interpretations, and report against our unified graph of financial data. We’re applying principles of software engineering and data systems to scale accounting.
We tackle the hard problems. Accounting does not need more duct tape.
We’ve rethought the field—its primitives, assumptions, and practices—while staying grounded by working closely with our customers. As engineers, we do our homework. We study the domain and talk to our users, and by doing so we earn the right to bring a fresh perspective to the problem of financial data.
The Role
Our Close product is the operating center for accounting and finance teams. Our product weaves collaboration, automation, and workflow tools with deeply-integrated financial data and reporting. Customers depend on Numeric to alert on their financial transactions, perform trend analyses, match money movement across accounts, and more as they close the books each month.
We’re looking for engineers who enjoy shipping in a tight feedback loop with customers, and take pride in raising the quality and robustness of the system in which they work.
You might be a fit if…
You practice “leave it better than you found it” with the systems in which you work. You’re the type who consistently refactors and improves the system, codebase, and tools as you go.
You appreciate tight feedback loops with active customers, and are energized by shipping visible changes to user
You’re comfortable reasoning about systems with regard to resilience, testing, and observability
You’re excited to build systems to support and manage AI development, enabling faster pace without losing stability and quality
What you need
3+ years of full-time experience building software, ideally some tenure of >2 years in one company
Fluency of backend fundamentals, including data structures, database fundamentals, performance concepts.
Code design skills to build robust, high-quality programs
Bonus points for…
B2B SAAS experience, especially in related areas like finance, accounting, or in other complex domains
Strong AI development workflow
Strong product thinking, user empathy, or design thinking
How we work
This role is in-person in New York City.
As an engineer at Numeric you will learn the domain, meet your users, and exercise substantial creativity and agency over product direction. You'll work with a high-pace, high-integrity team that loves collaboration.
We believe the best company is the one with the best ICs and we’ve built a culture to maximize great work. We believe great product & engineering come from a desire to win, a deep care for the craft, and a pragmatism in shipping for overall impact. As engineers we ground our work in our understanding of the users, the domain, and the goals for our organization.
We strongly believe we will only be successful if everyone on the team is anchored in our following set of core principles:
Own the Outcome: We own our results. We typically hire builders and give them large mandates with high-trust. Engineers are responsible not just for code, but for ensuring the product is solving the end problems of the users.
Brick by Brick: To win, our team needs to show up and execute in each domain every day.
Love the Game: We focus on the craft and a deep sense of giving a f*ck. We’re building a company full of people who are equally engaged and motivated.
Earn the right: Our ability to rethink how things are done depends on the trust and reputation we build by shipping quality products and improving the lives of our users.
SALY: We refuse to accept “Same As Last Year.” We bring fresh eyes to a stagnated and underserved domain. We’re driven by a first-principles approach to building better solutions.
