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.
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.
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
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.
