Contract Typescript Developer Jobs in Northborough, MA

Position Summary:

The Principal AIOps Engineer will build the platform that makes AI cheap, fast, safe, and observable at RxSense. As a direct report to the Director of AI Engineering, this role will own the infrastructure that every AI-powered product at RxSense depends on. This is a hands-on-keyboard position from day one, partnering with AI engineers, software engineers, data scientists, security, and finance to deliver deployment pipelines, agent runtime, eval frameworks, self-hosted model serving, and the developer harness that determines how fast every other engineer in the company can ship.

Essential Duties and Responsibilities:

• Build and maintain end-to-end deployment pipelines for AI-powered applications, including artifact builds, environment promotion, rollback, and observability hooks. Drive new greenfield deployment platforms from initial build to the default that AI teams ship on.
• Stand up and operate the runtime and lifecycle infrastructure for production agents, including deployment, versioning, monitoring, rate-limiting, and retirement. Define the deployment contract (config, secrets, tools, memory, evals) and the operational SLOs.
• Own how the organization provisions, rotates, scopes, and meters access to model provider APIs (Anthropic, OpenAI, and others). Build a key management layer that enforces per-team and per-app quotas, prevents leakage, and gives finance and engineering a clear view of spend.
• Build evals into the CI/CD pipeline so no agent or LLM-powered service ships without passing a defined eval bar. Design the framework so product teams can author their own evals against a shared harness, and so eval results gate promotion across environments.
• Stand up self-hosted inference for workloads where managed APIs aren't the right fit, including latency-sensitive paths, regulated data, cost optimization, and vendor redundancy. Own the serving stack, the autoscaling and GPU economics behind it, and the playbook for when a workload belongs to a managed provider versus internal infrastructure.
• Design and build the shared developer harness that every AI-powered service uses: prompt management, model routing, retries, tracing, eval hooks, and policy enforcement. Set the abstractions that determine how fast every other AI engineer can ship for the next three years.
• Partner with finance on cost visibility, including token accounting, per-feature cost attribution, and real-time spend observability.
• Write documentation, runbooks, and clear interfaces so the platform is adoptable by other engineering teams without hand-holding.
• Participate in code review and promote collaboration and best practices including simplicity, automation, sound design patterns, test coverage, and reusability.

Education/Experience/Competencies:

• BS (or higher, e.g., MS or Ph.D.) in Computer Science or related technical field involving coding, or equivalent technical experience.
• 6+ years of platform, infrastructure, or DevOps engineering, with at least 2 years building production infrastructure for AI/ML or LLM-powered systems. We care more about depth and drive than years on a resume.
• Deep hands-on experience designing and operating CI/CD pipelines for high-velocity engineering organizations, including artifact management, environment promotion, and progressive rollout.
• Strong AWS background, comfortable down to the IAM, networking, and container orchestration layers.
• Proven track record building developer platforms or internal tools that other engineering teams adopted by choice, not by mandate.
• Production experience with LLM-powered applications, including prompt management, model routing, retries, tracing, and the operational realities of running agents or chains in production.
• Hands-on coding fluency in Python or TypeScript, ideally both. This is a keyboard role, not an architecture-only role.
• Comfortable operating in a polyglot environment. The RxSense AI engineering stack spans Python, .NET, and TypeScript, and you will deploy and support services across all three.
• Comfortable owning the cost and reliability conversation with both engineering leadership and finance partners.
• Strong written communication and a bias toward documentation, runbooks, and clear interfaces.
• Proven analytical thinking and problem-solving skills.
• Excellent communication skills, both verbal and written.

Bonus Qualifications:

• Direct experience integrating with Anthropic, OpenAI, or other frontier model provider APIs at scale, including key management, quota enforcement, and capacity planning.
• Hands-on experience self-hosting models with vLLM, TGI, SGLang, or similar inference servers, including GPU autoscaling and cost optimization.
• Built or contributed to an eval framework that gated production deployments.
• Familiarity with agent runtimes and frameworks such as the Claude Agent SDK, LangGraph, or in-house equivalents.
• Working familiarity with .NET, enough to read code, debug a deploy, and pair with service owners.
• Background in healthcare, PBM, pharmacy, or another regulated data environment.
• FinOps experience, particularly attributing AI spend to features or business units.
• Kubernetes operator experience or comfort with custom controllers.
• Experience with Agile development methodologies, preferably both Scrum and Kanban
