Job Requirements This is an Onsite Role at Hartford, CT (3 days Onsite)About the

Role:

We're looking for engineers who can design and build production systems that combine strong softwarefundamentals with hands-on exposure to modern AI/ML tooling — specifically agentic AI workflows andModel Context Protocol (MCP) servers. You don't need to come from a pure AI/ML background; whatmatters is strong core engineering skills, sound architectural judgment, and the ability to pick up (or alreadyknow) how to integrate AI agents into real systems. This is a single posting covering both Senior and Leadlevels — candidates with 4-7 years of experience are encouraged to apply.

Must-Have Skills Python — strong, production-grade proficiency (primary language) Databases — solid relational/SQL fundamentals; schema design, query optimization, data modeling Cloud platform — strong hands-on experience with at least one of: Google Cloud Platform (GCP)(preferred), or AWS (acceptable alternative) 4+ years of professional software engineering experience

Design & Architecture Thinking Required:

Strong grounding in modular design — clear separation of concerns, well-boundedcomponents/services, low coupling / high cohesion Ability to design systems that scale horizontally — statelessness where it matters, partitioning/shardingstrategy, load distribution, avoiding single points of contention Working fluency in core design patterns and principles (e.g., SOLID, domain-driven boundaries,event-driven/async patterns, idempotency, caching strategies, API versioning) and knowing when toapply vs. avoid them Comfortable reasoning about tradeoffs: consistency vs. availability, latency vs. throughput, build vs. buy,synchronous vs.

async workflows For Lead specifically:

expected to drive these principles — set direction in design reviews, push back ondesigns that won't scale, and mentor others toward this way of thinking rather than just applying it.

API & Real-Time Integration Best PracticesStrong grasp of RESTful API design — resource modeling, versioning, pagination, idempotency forretries, proper status codes/error contractsPractical experience with WebSocket-based real-time communication — connection lifecyclemanagement, reconnection/backoff strategy, heartbeat/keep-alive handling, and graceful degradationwhen a socket dropsUnderstands tradeoffs between REST, WebSockets, and event-driven/streaming integration patterns,and picks the right one for the use caseFollows security best practices for integrations — authentication/authorization (OAuth2, token scoping),input validation, rate limiting, and safe handling of external payloadsDesigns integrations for observability and resilience — structured logging, timeouts, circuit breakers, andclear failure modes rather than silent dropsWhat We're Really Screening For Strong in Python + SQL/databases as a baseline Solid architectural instincts — modular, scalable design, not just "make it work" Proven in one major cloud (GCP strongly preferred, AWS acceptable) Comfortable or curious about Java (bonus, not blocker) Solid API/WebSocket integration practices — reliability, security, and observability by default Open to learning / already exposed to agentic
