## Job description

### **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 **senior 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:**

-   5+ 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!
