Job description

We’re looking for a technical architect who can drive development velocity across a team of 10-15 engineers building cloud-native applications. This is a hybrid role: deep hands-on technical leadership combined with people management.

What you’ll do

Lead the architecture, performance, and scalability of our Node.js-based platform running primarily on AWS. While our applications are deployed on AWS today, they are designed to be hyperscaler-agnostic, and you’ll ensure architectural decisions preserve that portability across GCP, Azure, and other cloud providers. You’ll own the technical direction of the platform, mentor senior engineers, and partner with product and engineering leadership to ship high-quality systems quickly.

You’ll also manage a team of 10-15 developers - setting goals, running 1:1s, growing careers, hiring, and removing blockers. You’ll balance roadmap delivery with engineering health: code quality, system reliability, on-call hygiene, and developer experience.

What we’re looking for

• 8+ years of software engineering experience, with 3+ years leading engineering teams
• Deep expertise architecting distributed systems on AWS (compute, networking, data, IAM, observability)
• Strong Node.js background and a clear point of view on building maintainable services at scale
• Experience designing platform-agnostic systems that can run on any major hyperscaler
• Track record of improving performance, scalability, and deployment velocity in production environments
• Proven ability to grow engineers, hire well, and run a team that ships consistently
  Nice to have
• Experience with multi-cloud or cloud-portable deployments (Kubernetes, Terraform, containerization)
• Background scaling SaaS platforms or developer-facing products
• AWS certifications (Solutions Architect Professional, DevOps Engineer)
