Job summary

Brivo is seeking a senior engineer to own the architecture and delivery of a high‑availability, low‑latency AI platform powering Brivo's core access control and video products. You will lead LLM orchestration, tooling, and guardrails, driving architectural decisions and guiding the team in a fast-paced environment.

You will join a high-impact team building AI-powered experiences, including multi-agent orchestration, real-time streaming, and deep platform integrations.

Qualifications

• 5+ years of professional experience designing, developing, and deploying highly available, scalable software solutions.
• 5+ years of deep, hands-on experience with Node.js and TypeScript, including serverless development on AWS Lambda.
• Direct experience building and operating MCP servers (or comparable LLM tool/plugin servers) in production.
• Proven experience building production REST API services with Express, including authentication, rate limiting, input validation, and OpenAPI/Swagger documentation.
• Hands-on experience developing LLM-enabled / generative AI applications—tool calling, multi-agent orchestration, and prompt engineering.
• Strong experience with AWS, containerized deployments, and CI/CD tools.
• Deep practical experience with PostgreSQL and query optimization.
• Experience with real-time streaming (Server-Sent Events and/or AWS SQS) and Redis for state management.
• BS degree in Computer Science, Engineering, or related field; advanced degree preferred.
• Exceptional written and verbal communication skills.

Responsibilities

• Design, build, and operate MCP (Model Context Protocol) servers and tool registries exposing platform capabilities to LLMs and agents safely and reliably.
• Deliver generative AI capabilities across the platform—prompt engineering, tool/function calling, agent routing, and stateful human-in-the-loop workflows that are safe, responsive, and cost-efficient.
• Build and maintain AI safety guardrails and resumable tool workflows using Redis-backed checkpointing.
• Spend approximately 70% of your time coding, architecting and developing scalable API and platform services (Node.js/TypeScript, Express) and AWS Lambda delivery.
• Drive technical design, document ADRs, and participate in code reviews to maintain high engineering standards.
• Own cloud infra and deployment pipelines using AWS (Lambda, SQS, Secrets Manager, SSM), CI/CD tooling, feature flags, and externalized config to automate provisioning.
• Collaborate with product and design in an Agile team; assist Team Lead with project scoping, sprint planning, and backlog grooming.
• Troubleshoot and resolve high-impact production issues; identify security vulnerabilities and optimize database models in PostgreSQL.
• Mentor teammates, promote best practices, and lead architectural improvements across engineering.
• Partner with other teams to drive architectural and technical improvements aligned with Brivo’s mission.
