Platform & Reliability Engineer

We are hiring a Platform & Reliability Engineer!

As our Platform & Reliability Engineer, you’ll be the architect of how we deploy, scale, and operate our systems to keep payments flowing smoothly. You’ll own the reliability and performance of our platform, from designing SLOs and incident response processes to optimizing costs and developer workflows. As the first platform-focused hire at a fast-growing, Sequoia-backed fintech startup, you’ll have the opportunity to define best practices, shape our engineering culture, and ensure we ship software that is fast, secure, and resilient at scale.

What You’ll Do:

• SLOs & error budgets - Define, track, and evangelize latency and availability targets for our payment APIs.
• Observability - Deploy Cloud Monitoring, Cloud Trace, Error Reporting, and dashboards; integrate alerts via Incident.io and Slack for on-call.
• Incident lifecycle - Establish blameless postmortems, guardrails, and runbooks to drive learning and prevent recurrence.
• CI/CD golden path - Codify Cloud Build pipelines and automated canary rollouts for Cloud Functions / Cloud Run.
• Infrastructure as Code - Manage GCP resources; embed security, IAM least-privilege, and cost controls by default.
• Performance & cost tuning - Profile hot paths (BigQuery, Firestore, Pub/Sub), and implement caching or concurrency improvements to keep user latency < 100 ms.
• Developer tooling - Eliminate toil by improving local-to-prod parity, secrets management, and spinning up environments with a single command.
• Culture carrier - Instill reliability thinking across engineering and product as the first platform-focused hire.

What We're Looking For:

• At least 5+ years of experience building/operating production systems at scale, ideally on Google Cloud or a similar serverless stack, ideally in fast-paced or startup settings.
• Hands‑on Fluency with Firebase, Cloud Build, Cloud Run/Functions, Pub/Sub, Cloud SQL/Spanner, VPC Service Controls.
• Strong coding in Python or Go for automation, with an eye on maintainability.
• Demonstrated record of driving observability, on‑call and cost optimisation in a fast‑moving environment.
• Excellent collaboration and communication skills to work effectively with cross-functional teams.
• Experience in payments, PCI‑DSS, or crypto settlement flows is a bonus. 

Tech note: we are 99 % serverless. There are no pet VMs to patch, but the stakes are higher: every cold‑start, DB connection pool and retry policy can impact real money transfers. You’ll architect for resiliency and velocity.

Our Culture:

• Fast-paced and dynamic – We’re a growing startup that moves quickly.
• Tech-driven – We leverage technology to address our users’ biggest challenges.
• Ownership and communication – We value people who take full ownership and communicate well across teams.
• Continuous learning – You’ll have the opportunity to work alongside industry experts and enhance your expertise in risk management.

Why Join Us:

• Competitive salary + equity plan
• 21 days PTO
• Benefits: annual medical allowance, productivity budget, gym membership & wellness subsidy
• Annual team retreat trip
• Be part of a team backed by Sequoia Capital with a healthy runway

Requirements:

• 5+ years of experience in platform, reliability, or infrastructure engineering.
• Proficient in GCP, infrastructure as code, and automation scripting.
• Familiar with observability, CI/CD, and modern cloud-native architectures.
• Bachelor's degree or equivalent practical experience.
• Work visa sponsorship available.
