Numeral · United States
Numeral is transforming how taxes get done by eliminating the burden of complex regulations across 47 states and 50+ countries. We’re the largest and fastest-growing AI-native tax solution, serving over 2,500 paying customers and tripling revenue annually. Join us to define foundational architecture and build scalable, secure backend systems that power our platform.
About the Role
We’re looking for a foundational Full-Stack Engineer who thrives in ambiguity, enjoys building complex distributed systems, and wants to define foundational architecture in a fast-growing early-stage startup. You’ll lead the design and implementation of APIs, services, and infrastructure that underpin our platform. You’ll also help drive engineering strategy, product execution, and cultural foundations alongside leadership.
What You Will Do
Design and build scalable, secure backend services and APIs from scratch.
Make architectural decisions that optimize for speed, data integrity, and long-term maintainability.
Collaborate closely with product, design, and data teams to develop performant systems that power key customer workflows.
Own infrastructure, observability, and performance for the services you build.
Help shape engineering best practices, code quality, and our overall backend culture.
What We Are Looking For
7+ years of experience building backend systems in high-growth environments.
Fluency with backend technologies like Node.js, PostgreSQL, Redis, and cloud services (AWS preferred).
Experience designing robust APIs and distributed systems at scale.
Strong product sensibility—able to balance performance, flexibility, and speed.
Startup mindset: Not scared of ambiguity and hungry for rapid growth.
Intensity & Ownership: This is not a 9-5 — we’re scaling rapidly and have a massive opportunity ahead of us.
Customer Obsession: You deeply care about the user experience and solving their problems.
Even Better
Experience in payments, tax, accounting, or regulatory tech.
Infrastructure or platform engineering background (e.g., CI/CD, observability).
Experience scaling monolith-to-service architectures or event-driven systems.
Familiarity with GraphQL, Kafka, Terraform, or container orchestration tools.
We’re primarily hiring in our SF and NY offices, but do hire remotely in some cases. This is not a 9-5 — we’re scaling rapidly and have a massive opportunity ahead of us. Your work matters and people will see it!
