Software Engineer

Company: WRITER
Location: San Francisco, New York City, or Seattle (Hybrid)

About WRITER:
WRITER is the leading platform for enterprises to orchestrate AI-powered work. Our vision is to expand human capacity through superintelligence. We empower hundreds of companies with a trustworthy AI platform that unites IT and business teams for enterprise-wide transformation. Valued at $1.9B and backed by top investors, WRITER is solidifying its position as the leader in enterprise generative AI.

About the Role:
Join WRITER as an exceptional Software Engineer and be at the forefront of expanding human capacity by building the next generation of AI-powered solutions. You will develop a state-of-the-art platform leveraging cutting-edge generative AI technologies, including large language models and agentic workflows, to deliver seamless, scalable, and secure enterprise applications. This is a unique opportunity to shape the future of AI and impact how the world works.

This is a hybrid role based in our San Francisco, New York City, or Seattle hubs, reporting to the Senior Director, Engineering.

What You'll Do:

• Design and deliver secure, scalable AI integration platforms connecting enterprise systems for mission-critical automation.
• Contribute to the AI integration client ecosystem, defining secure connections to external tools, data sources, and enterprise systems.
• Own backend service design for high-throughput, low-latency APIs enabling reliable agent workflows and complex cross-system orchestration.
• Set technical direction for identity, authentication, and trust boundaries across integrations (OAuth, API key, service-to-service), balancing developer velocity with security and compliance.
• Partner with product and engineering leaders to shape the roadmap, define technical strategy, and translate 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, and mentorship of 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 the 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.
• Embody core values of Connect, Challenge, and Own.

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 and learning & development
• Company-wide off-sites and team off-sites
• Competitive compensation, company stock options, and 401k
