Senior Software Engineer - Platform

The Opportunity 📈

Our feature teams can only move as fast as the platform underneath them, and we want to help them move faster. As a Platform Engineer, you’ll contribute to the work that makes our platform stronger, from moving our data layer onto RDS, to tightening security and compliance across our multi-account AWS organization, to building tooling that speeds up every team shipping on top of it. You’ll review and test your teammates’ work, and partner with feature teams and other stakeholders to shape what our platform can do next.

What You'll Build (Your First 6 Months) 🛠

* By day 60: Standardize and optimize our logging for AI-supported troubleshooting across the platform.

* Day 61-180: Implement processes and infrastructure for AI agents to autonomously open PRs to resolve dependency vulnerabilities and other issues

* And more platform and security-related improvements TBD!

How You'll Make an Impact

Build the platform. You'll work with the engineering manager to identify and plan projects, then execute them using agentic engineering methods.

Harden data and security. You'll deliver the migration, security, and compliance work that keeps our data stores, APIs, and cloud infrastructure safe and reliable.

Enable the feature teams. You'll assist other teams with data and security requests, and review other engineers' code, so everyone ships faster on a solid foundation.

What We're Looking For

The Non-Negotiables:

* Object-oriented programming language with strong data and architecture skills — production experience building backend services and APIs, and current best practices in data modeling and system architecture

* Platform security — you've secured platform-layer components, including data stores, APIs, and cloud infrastructure, applying current best practices for access control, encryption, and audit logging

* Infrastructure and automation — hands-on experience building and operating production infrastructure with infrastructure as code (CDK, Terraform, or CloudFormation) and CI/CD pipelines

The Nice-to-Haves:

* Experience in healthcare setting, or another heavily regulated domain

* Experience building and using custom agents

* Experience with Typescript, AWS, serverless functions, PostgreSQL

You'll Thrive Here If…

* You make a plan and execute to that plan and timeline.

* You identify and report timeline issues early.

* You identify and champion opportunities to improve the ecosystem you work in.

* You keep up with current best practices, including AI-assisted engineering.

* You give direct, useful feedback in code review.

* You request and give help when needed.

* You write things down so the next engineer can rely on them.
