Senior Software Engineer - Infrastructure in Mountain View
Job DescriptionJob Description
Role Description
We’re seeking a Senior Software Engineer to join our Infrastructure team within Platform. You’ll
join a small, focused team with high ownership and closely collaborate with the Technical Lead
and Director of Platform on architecture and delivery.
The Infrastructure team builds and operates shared services that every engineering team
depends on (authentication, authorization, developer tooling, notifications, and public APIs).
Rather than owning a single product, you’ll work across foundational platform capabilities that
serve both internal engineering teams and external partners.
Your primary focus will be two high-priority initiatives:
1. Developer Portal — Build a production-grade, partner-facing developer platform that
delivers an industry-leading onboarding and integration experience. Partners will use this
portal to discover APIs, manage credentials, access interactive documentation, view
usage metrics, search request logs, and integrate with the Client's platform with
minimal support from our team.
2. Notification Service — Expand our notification platform to support in-app notifications,
event-driven callbacks (webhooks), and integration with delivery and engagement
reporting from providers like SendGrid and Twilio (e.g., click tracking, bounce reporting,
delivery status).
What You’ll Do
• Platform Development: Support designing and building the Developer Portal including
account management, interactive API documentation, request log search, and usage
metrics dashboards.
• API Design: Build tooling that transforms internal Swagger/OpenAPI specs into
partner-facing API documentation. Managing API Gateway routes, stripping internal-only
fields, normalizing auth schemes, and producing consistent error models and versioning.
The underlying APIs are built by domain teams; your focus is making them clean,
consistent, and ready for external consumption.
• Infrastructure as Code: Write and maintain Terraform/Terragrunt configurations for AWS
services including API Gateway, Lambda authorizers, Cognito, and supporting
infrastructure across multiple environments (dev, QA, production).
• Notification Platform: Extend the notification service to handle in-app notifications,
webhook delivery, and event ingestion from third-party messaging providers.
• Security & Auth: Work within and refine our existing authorization system, covering
Cognito-based , M2M and user token validation, API key management, and API
Gateway authorization to support partner access patterns.
• Developer Experience: Build services and tooling that enable external partners to
onboard, authenticate, test integrations, and troubleshoot issues independently.
• Operations & Reliability: Support day-to-day operation of Infrastructure services,
including monitoring, incident response, debugging production issues, and partnering with
SRE to ensure availability and performance.
• Technical Leadership: Lead technical design discussions, mentor engineers, conduct
thoughtful code reviews, and help define engineering standards.
Qualifications
Required
• 5+ years of professional software engineering experience building production backend
services or shared platform capabilities.
• Strong proficiency with Node.js, TypeScript, and NestJS (or comparable backend
frameworks).
• Experience with AWS services including API Gateway, Lambda, Cognito, IAM, and
CloudWatch.
• Hands-on experience writing and maintaining Terraform or Terragrunt for production
infrastructure.
• Experience designing and implementing authentication and authorization systems using
OAuth2, JWT, OpenID Connect, or AWS Cognito.
• Experience designing and implementing REST APIs using OpenAPI/Swagger
specifications.
• Experience building reusable SDKs, shared libraries, or internal developer tooling
consumed by multiple teams.
• A security-first mindset and attention to least-privilege, secret management, and audit
logging when designing systems that handle credentials, API keys, and access tokens.
• Strong understanding of API lifecycle management, versioning, and backwards
compatibility.
• Experience with Git workflows and modern CI/CD pipelines.
• Professional proficiency in English (both written and spoken).
Nice to Have
• Experience building Developer Portals, API platforms, or partner-facing developer
products.
• Experience integrating with email and messaging platforms such as SendGrid, Twilio, or
similar services.
• Experience with Kubernetes and containerized applications.
• Experience with observability platforms such as Datadog, OpenTelemetry, or CloudWatch.
• Familiarity with webhook delivery systems.
• Experience with GitHub Actions
About the Team
The Developer Portal and Partner API Platform initiative is owned by the Infrastructure team in
partnership with Site Reliability Engineering (SRE). Your primary users are internal product
engineering teams and external API partners.
We use AI-assisted development tools extensively and expect engineers to leverage them
effectively.
What Success Looks Like
A successful engineer in this role will deliver a self-service developer portal that reduces partner
onboarding from days of back-and-forth to hours of independent integration, build the tooling
pipeline that keeps partner-facing API documentation accurate and consistent as domain teams
ship changes, expand the notification platform to support reliable in-app notifications, event
reporting from messaging providers, and contribute to a platform that scales.
