• Collaborate closely with the Data, Neuro, and Integrations teams to define data contracts and weave their services and data assets into a unified API product

• Work with the Forge (Platform) team to implement best practices for CI/CD, infrastructure as code, security, and observability for the API platform

• Define and champion API design standards, versioning strategies, and documentation to create a world-class developer experience for both internal and external partners

• Define and implement testing strategies (unit, integration, and end-to-end tests)

• Set up and maintain automated testing pipelines to ensure code quality and reliability

• Implement robust authentication, rate-limiting, monitoring, and alerting to ensure the platform is reliable and secure

• Champion observability and error handling (e.g. structured logging, error tracking via tools like Grafana)

• Mentor other developers and help establish a culture of technical excellence, simplicity, and long-term ownership within the new Fabric team

• Contribute to hiring and onboarding new engineers into the team
  

Requirements

• B.S. or M.S. in Computer Science or equivalent experience

• 6-8+ years of experience in fullstack or backend development, with a strong emphasis on building scalable, public-facing APIs and services

• Deep expertise in server-side Python, JavaScript/TypeScript and Node.js, with a proven track record of delivering high-quality, scalable web services

• Hands-on experience with building and consuming APIs and working with cloud infrastructure (GCP preferred) is required

• Solid experience with databases like PostgreSQL and MongoDB

• Familiarity with platform engineering concepts, including containerization (Docker, Kubernetes) and Infrastructure as Code (Terraform), is a strong plus

• Experience or a strong interest in working with AI/LLM APIs and building applications for agent-based ecosystems is a plus

• Proven experience in leading technical projects or mentoring other developers, with a focus on improving team skills and code quality

• Excellent communication skills and a collaborative approach to working with product managers and cross-functional stakeholders to translate business needs into technical solutions
