Senior Fullstack Developer

We're aiming to bring a Senior Fullstack Developer onto our expanding team. This position connects high-level business priorities with hands-on technical implementation across a widely distributed, multi-department organization. You'll infuse structured engineering rigor into fluid, still-forming problems, all while contributing to how the organization adopts and integrates new technology. It's an opportunity to make a real difference in how enterprise systems scale and connect.
Responsibilities
Work hand-in-hand with product owners and stakeholders across IT, Sales, Finance, and HR, coordinating schedules to support live, direct collaboration
Convert vaguely defined internal use cases into robust architecture designs, UX/flow diagrams, API contracts, and a development-ready backlog for the team in India
Develop and interconnect agentic workflows spanning enterprise systems such as Salesforce, ServiceNow, Jira, Glean, and Oracle HCM
Take charge of demanding integration projects, covering authentication setup, MCP tool access, data contract design, RBAC configuration, error handling, and production launch
Sync up daily with the India-based team to resolve outstanding questions, review pull requests, eliminate integration hurdles, and maintain quality standards ahead of release
Build out prototypes when needed, spanning UI components, agent flow design, or MCP/LLM integration work, then deliver a production-ready backlog to the India team
Incorporate security, observability, and reusability principles into every build so agents deliver lasting value rather than functioning as one-time demos
Requirements
Three-plus years of hands-on, relevant full-stack engineering experience, supported by a current and active delivery record
Strong expertise in TypeScript/JavaScript paired with a modern frontend framework such as React or an equivalent tool
Solid backend development background using Node.js or Python, combined with strong API and integration design capabilities
Established track record delivering AI/LLM-driven solutions, including tool calling, RAG, agent frameworks, MCP, prompt workflows, or similar practical delivery
Demonstrated ability to translate stakeholder workshop findings into functional architecture and a practical, actionable backlog
Hands-on AWS delivery experience covering Lambda, API Gateway, ECS/EKS, S3, RDS/DynamoDB, IAM, and CloudWatch, plus enterprise authentication approaches such as SSO/Okta and RBAC
Capable communicator who can lead technical discussions in English with US-based stakeholders, holding working fluency at B2 level or higher, converting business needs into agentic architecture
Nice to have
Understanding of MCP gateways, LLM gateways, model routing approaches, policy/audit tooling, and cost/usage monitoring systems
Background implementing OpenTelemetry or similar observability tools to monitor agent traces, tool call behavior, latency, and failure patterns
Practical exposure to platforms such as Salesforce, Gong, Clari, Glean, ServiceNow, Oracle HCM, Concur, or similar HR/IT tools
Experience transforming internal platforms or early prototypes into reliable, enterprise-grade production solutions
