Full Job Description

📋 Description

• Design and deliver secure, scalable AI integration platforms that connect enterprise systems and power mission-critical automation.
• Contribute to the design and evolution of the AI integration client ecosystem, defining how AI applications securely connect to external tools, data sources, and enterprise systems.
• Own backend service design for high-throughput, low-latency APIs that enable reliable agent workflows and complex cross-system orchestration.
• Set technical direction for identity, auth, and trust boundaries across integrations including OAuth, API key, and service-to-service authentication, balancing developer velocity with security and compliance.
• Partner with product and cross-functional engineering leaders to shape roadmap, define technical strategy, and translate ambiguous business goals into durable platform capabilities.
• Lead production excellence through a metrics-first reliability strategy, defining and enforcing SLOs/SLAs, maturing observability, and driving resilience, incident readiness, and performance optimization at scale.
• Raise the engineering bar through architecture reviews, pragmatic design standards, rigorous testing strategy, and mentorship of senior and mid-level engineers.
• Build and operate production backend systems using TypeScript, Deno, Node.js, or Bun, with scope and leveling flexible from Senior to Staff based on architectural impact and leadership.
• Design and ship API-driven platform services and distributed systems including microservices, event-driven patterns, and secure service-to-service communication.
• Build AI integration layers such as MCP clients/servers, tool orchestration, external API connectors, and auth mediation, focusing on production implementation rather than prompt or model experimentation.
• Apply deep hands-on knowledge of authentication and security patterns for third-party integrations including OAuth2/OIDC, API keys, token lifecycle, secret management, and least-privilege access.
• Work with cloud-native environments on AWS, GCP, or Azure, including containerized workloads using Docker and Kubernetes, CI/CD pipelines, and production operations.
• Implement observability and reliability engineering practices including defining/operating service metrics, SLOs/SLAs, alerting, incident response, and performance tuning.
• Apply solid backend fundamentals in modern server frameworks and data systems such as TypeScript/Node or Python ecosystems and PostgreSQL, selecting appropriate tools for system requirements.
• Lead through ambiguity by partnering cross-functionally, mentoring engineers, driving technical decisions, and owning delivery from design through production.
• Embody core values of Connect, Challenge, and Own by building strong partnerships across teams, challenging conventional thinking to drive innovation, and taking ownership of work with a focus on delivering meaningful impact and excellence.

🎯 Requirements

• 5+ years of software engineering experience building and operating production backend systems using TypeScript, Deno, Node.js, or Bun
• Strong experience designing and shipping API-driven platform services and distributed systems including microservices and event-driven patterns
• Practical expertise building AI integration layers such as MCP clients/servers, tool orchestration, external API connectors, and auth mediation
• Deep hands-on knowledge of authentication and security patterns for third-party integrations including OAuth2/OIDC, API keys, and secret management
• Proven cloud-native experience on AWS, GCP, or Azure including Docker/Kubernetes, CI/CD, and production operations
• Strong experience with observability and reliability engineering including SLOs/SLAs, alerting, incident response, and performance tuning
