Sr. AI Engineer

What We Need

We are looking for an AI Sr. Engineer to lead one or more of our high-performing AI engineering teams at Blue Cross Blue Shield of Massachusetts. You'll be a hands-on technical leader - combining deep expertise in machine learning, agentic AI systems, and cloud platforms with strong mentorship skills to guide a talented group of engineers. This role sits at the heart of our AI initiatives, where you'll drive technical excellence while building innovative solutions that directly impact our members and the healthcare industry.

You'll own the technical direction, delivery, and quality of your team's work, ensuring our AI solutions are well-architected, scalable, and production-grade. This is a critical role for someone who is equally comfortable writing code and reviewing architecture, mentoring junior engineers, and making technology decisions that shape our AI platform for years to come.

Your Day to Day

* Provide technical leadership- Guide and mentor a team of AI Engineers; establish and enforce architectural best practices, coding standards, and engineering excellence; conduct code reviews that elevate team capability

* Lead solution design- Own the detailed technical design and implementation of complex agentic AI systems, Generative AI integrations, RAG architectures, and infrastructure; make technology and framework decisions with your team

* Oversee delivery and execution- Collaborate closely with Product Owners to refine technical requirements, estimate effort, and deliver high-quality AI features on time; balance quality with velocity

* Build scalable AI systems- Design and implement production-grade AI agents and models; manage performance, scalability, and reliability; establish monitoring, evaluation, and observability for AI workloads

* Troubleshoot complex problems- Serve as the primary technical escalation point; debug complex issues in ML pipelines, agent systems, cloud infrastructure, and integrate systems; guide your team to solutions

* Hands-on coding- Spend 40-50% of your time writing code alongside your team; stay grounded in day-to-day engineering challenges and remain credible as a technical leader

* Mentor and grow talent- Actively coach AI Engineers; help them develop deeper expertise in ML fundamentals, agentic architectures, cloud platforms, and system design; create learning opportunities and growth paths

* Evaluate new technologies- Stay current on emerging tools, frameworks, and libraries (new agent frameworks, LLMs, MLOps platforms); assess fit for our platform and recommend adoption when valuable

* Drive engineering practices- Establish rigorous code review processes, knowledge-sharing sessions, documentation standards, and testing practices that scale as the team grows

* Collaborate across teams- Partner with Data Engineering, Platform Engineering, Product, and Operations to ensure AI solutions integrate cleanly with the broader platform and meet healthcare/compliance requirements

We're Looking For

* Bachelor's degreein Computer Science, Engineering, Technology, or a related field

* 8+ yearsof hands-on experience with machine learning, deep learning frameworks (TensorFlow, PyTorch, scikit-learn), and building real-world ML systems

* 2+ yearsof proven hands-on expertise developingagentic AI solutions- designing agents that leverage Retrieval Augmented Generation (RAG), function calling, multi-step reasoning, tool use, and fine-tuning techniques

* Deep cloud platform expertise- hands-on experience with at least two of AWS, Google Cloud, or Azure; strong knowledge of cloud services for ML (SageMaker, Vertex AI, Azure ML) and MLOps tools (Docker, Kubernetes, CI/CD)

* Production ML experience- proven track record of managing the performance, scalability, reliability, and monitoring of AI models and agents in production environments

* Team leadership experience- demonstrated ability to mentor engineers, conduct technical reviews, guide architectural decisions, and lead small technical teams or projects

* Strong communication skills- comfortable presenting technical concepts to both engineers and non-technical stakeholders; excellent written communication for design docs and architectural decisions

* Python proficiency- deep expertise in Python; comfortable with other languages as needed

* System design thinking- ability to design scalable, maintainable, fault-tolerant systems; understand trade-offs between complexity, performance, and cost

* Hands-on builder mindset- You're still writing code and shipping features; you don't sit in meetings all day; you stay grounded in engineering reality

Preferred:

*Solution Architect Associate/Professional certification (GCP or AWS)

* Exposure to healthcare IT, compliance requirements (HIPAA), or regulated industries

* Knowledge of evaluation frameworks for LLM/agent quality

* Familiarity with Generative AI frameworks (LangChain, LlamaIndex, LangGraph, Vertex AI Agent Builder)

What You Bring

* Deep technical expertise- You understand machine learning fundamentals, the practical challenges of building agentic systems, and how to architect them for production at scale

* Mentorship instinct- You genuinely enjoy helping others grow; you lead through teaching and example, not authority; your team performs better because of your guidance

* Technical judgment- You make sound decisions on tools, frameworks, and architectures with incomplete information; you balance perfectionism with pragmatism

* Growth mindset- You're learning in a rapidly evolving field (agentic AI); you stay current and bring new ideas back to the team

What You'll Gain

* Work on complex, high-impact problems - designing intelligent agents that help healthcare professionals make better decisions, reduce administrative burden, and serve members more effectively

* Stay hands-on while leading - you get to write code, ship features, and mentor your team; you don't have to choose between technical work and leadership

* Exposure to cutting-edge AI technology - early access to new LLMs, agent frameworks, and cloud AI capabilities; opportunity to evaluate and shape adoption across the platform
