About the role

Key responsibilities & impact

Own the technical architecture of the Tetra Apps platform, including application development, packaging, provisioning, routing, authentication, isolation, observability, upgrades, and retirement.
Design and evolve the app proxy and routing layer, container provisioning and lifecycle on ECS, per-app identities, and install, upgrade, and rollback paths across multitenant cloud and customer-hosted environments.
Design security for tenant and per-user data boundaries, delegated authorization, secrets handling, browser security, and server-side approval and install gates.
Threat-model a platform that runs external code, including agents.
Own production readiness through metrics, tracing, SLIs, SLOs, alerting, incident runbooks, capacity planning, and cost planning.
Partner with DevOps and platform teams on infrastructure-as-code and multi-tenant deployment.
Own templates, TypeScript and Python SDKs, CLI, local development loop, and builder documentation.
Run sprint and quarterly planning with the product manager; scope, estimate, sequence, and manage commitments.
Make maintenance and technical-debt paydown visible and lead ROI discussions.
Lead design reviews, write architecture RFCs and decision records, represent the platform in weekly architecture review, and raise engineering quality through review and pairing.
Ship code and components across TypeScript/Node.js services, React web apps, AWS architecture, client SDKs, and IaC/CI/CD automation.
Support field engineers and customers building and debugging apps in their environments, converting findings into platform improvements.

Requirements

What you’ll need

10+ years of professional software engineering, including time as the technical lead or architect of a platform that external teams build on.
Shipped and operated a multi-tenant application platform, app hosting/runtime, PaaS, plugin or extension system, or internal developer platform in production with external users.
Deep, hands-on container experience: Docker image pipelines, ECS or similar task and service definitions, networking, service discovery, scaling, and cost.
Security engineering as a first-class skill: IAM and least privilege, identity propagation, tenant isolation, browser security, secret management. You have secured multi-tenant systems for running untrusted code.
Adapted to the AI step change in software development and can apply AI while maintaining correctness, security, and architectural fit.
Strong production experience with AWS: ECS, ALB/NLB, VPC, IAM, KMS, CloudWatch, S3, Lambda.
Infrastructure-as-code with CloudFormation or an equivalent.
Full-stack fluency: expert TypeScript/Node.js for backend services and APIs; solid React, ideally with module federation or micro-frontend experience; working Python for SDKs and tooling.
Demonstrated API-first design: REST and OpenAPI, versioning, backward compatibility, and clear error contracts.
Observability skills: OpenTelemetry, SLI/SLO definition, distributed tracing.
Experience running sprint and quarterly planning, writing design docs and migration plans, and holding engineers to commitments through influence and authority.
Experience operating, extending and improving messy, live production systems without breaking existing customers.
Visa sponsorship is not currently provided for this position.
