The Opportunity
We’re looking for a Senior Software Engineer (Platform) who wants high ownership: leading projects end-to-end, improving how services in our Node.js/TypeScript stack are built and operated, and creating paved paths that reduce toil across engineering. This is not a traditional DevOps or SRE role. We’re looking for a strong software engineer who is comfortable working in our Node.js/TypeScript ecosystem while improving platform and infrastructure capabilities.
This role can be based in LATAM or Europe. We cannot hire in the USA for this position.
Within your first few months, you'll:
- Ship meaningful improvements to our infrastructure, reliability and developer experience
- Take ownership of key platform areas and processes
- Partner with product engineers to understand pain points, unblock delivery, and raise standards and improve how we operate
Preferred skills and background:
- Strong experience with TypeScript/Node.js
- Experience designing and operating production workloads on AWS, including services such as ECS/Fargate, Lambda, API Gateway, EventBridge, Application Load Balancers, and VPC networking.
- Familiarity with infrastructure-as-code (Terraform)
- Experience operating and supporting the systems you build, not just shipping and moving on
- Clear written communication. We're a distributed team, and documentation matters
It's also awesome (but not required) for you to have:
- Experience with MongoDB, OpenSearch/Elasticsearch, or Redis/Valkey
- Familiarity with observability tooling (OpenTelemetry, Datadog, etc.)
- Experience building internal platforms or developer tools
- Familiarity with microservices / event-driven / serverless architectures
- Experience with networking (DNS, load balancing, VPCs, etc.)
How we work
We’re a globally distributed team.
We default to asynchronous communication, keep meetings lightweight, and rely on strong written docs to stay aligned. Our core stack is Node.js/TypeSc
