> As a Software Engineer, you will design and deliver secure, scalable AI integration platforms, connecting enterprise systems and powering mission-critical automation. You will contribute to the AI integration client ecosystem and own backend service design for high-throughput, low-latency APIs.

## Job Description

## What you’ll do
* Design and deliver secure, scalable AI integration platforms that connect enterprise systems and power mission-critical automation.
* Contribute to the design and evolution of our 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 (OAuth, API key, service-to-service), 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.

## What you need
* 5+ years of software engineering experience building and operating production backend systems using Typescript, Deno, Node.js, or Bun; scope and leveling can flex across Senior to Staff based on architectural impact and leadership.
* Strong experience designing and shipping API-driven platform services and distributed systems, including microservices, event-driven patterns, and secure service-to-service communication.
* Practical expertise building AI integration layers (e.g., MCP clients/servers, tool orchestration, external API connectors, auth mediation), not just prompt or model experimentation.
* Deep hands-on knowledge of authentication and security patterns for third-party integrations (OAuth2/OIDC, API keys, token lifecycle, secret management, least-privilege access).
* Proven cloud-native experience on AWS, GCP, or Azure, including containerized workloads (Docker/Kubernetes), CI/CD, and production operations.
* Strong experience with observability and reliability engineering, including defining/operating service metrics, SLOs/SLAs, alerting, incident response, and performance tuning.
* Solid backend fundamentals in modern server frameworks and data systems (e.g., TypeScript/Node or Python ecosystems, PostgreSQL), with ability to choose the right tool for the system; experience with Python is a plus but not required.
* Demonstrated ability to lead through ambiguity: partner cross-functionally, mentor engineers, drive technical decisions, and own delivery from design through production.
* You embody our core values of Connect, Challenge, and Own. You build strong partnerships across teams, challenge conventional thinking to drive innovation, and take ownership of your work with a focus on delivering meaningful impact and excellence.

## Benefits & perks (US Full-time employees)
* Generous PTO, plus company holidays
* Medical, dental, and vision coverage for you and your family
* Paid parental leave for all parents (16 weeks)
* Fertility and family planning support
* Early-detection cancer testing through Galleri
* Flexible spending account and dependent FSA options
* Health savings account for eligible plans with company contribution
* Annual work-life stipends for:
  * Wellness stipend for gym, massage/chiropractor, personal training, etc.
  * Learning and development stipend
* Company-wide off-sites and team off-sites
* Competitive compensation, company stock options and 401k
