About the role

About Numeral:

  • Numeral is transforming how taxes get done. Digital businesses are currently bogged down by a painful web of regulations across 47 states and 50+ countries. We’re eliminating this burden so teams can focus on their core mission.

  • We’re the largest and fastest growing AI-native tax solution. Started in 2023, Numeral has raised over $57M from Benchmark, Mayfield, Y-Combinator, and many others. We now serve over 2,500 paying customers and have more than tripled our revenue every year in our history.

  • We’re primarily hiring in our SF and NY offices, but do hire remotely in some cases

About the role:

We’re looking for a foundational Software Engineer (Infrastructure) who thrives on solving complex distributed systems problems at scale. You’ll design and build core infrastructure , improve service reliability and observability , and ensure the platform’s scalability as we handle increasing transaction volumes and integrations.

This is a high-leverage, foundational role: your work will define the architecture and technical direction of our infrastructure platform while directly impacting our customers’ experience and the company’s trajectory.

What you’ll do:

  • Design and build highly scalable, secure, and reliable infrastructure to support critical APIs, services, and data pipelines.

  • Lead infrastructure architecture decisions for performance, observability, and fault tolerance.

  • Drive improvements in system reliability, monitoring, and incident response.

  • Collaborate closely with product, platform, and data engineering teams to enable rapid feature development without compromising stability.

  • Automate infrastructure management through infrastructure-as-code , CI/CD pipelines, and container orchestration.

  • Champion best practices in operational excellence, disaster recovery, and distributed systems design.

What you’ll bring:

  • 7+ years of experience building and scaling backend or infrastructure systems in high-growth environments.

  • Proficiency in Node.js, PostgreSQL, Redis, and AWS (or equivalent cloud platforms).

  • Experience managing containerized workloads using tools like Kubernetes, ECS, or similar.

  • Expertise in observability tooling (e.g., Datadog, Prometheus, OpenTelemetry) and monitoring pipelines.

  • Proven ability to design fault-tolerant, distributed systems at scale.

  • Strong debugging and performance optimization skills across the stack.

  • Exceptional collaboration and communication skills, with experience partnering cross-functionally.

  • 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.

What we offer:

  • Competitive salary and equity - you’ll share directly in the company’s success

  • Full medical, dental, and vision coverage

  • Wellness perks like Headspace and the Peloton One App

  • 401(k) to help you build long-term financial security

  • Lunch and snacks when you’re in the office

  • Regular team offsites and company events as we grow

  • A culture built on ownership - your work matters and people will see it!
