Lead Full Stack Software Engineer

Lead Full Stack Engineer - Application Modernization & Agentic Solutions | Remote (Hybrid/Onsite preferred near Rochester NY, Irvine CA, or Frisco TX)

About the Role

We're looking for a hands-on technical leader to drive architecture and delivery on large-scale, multi-vendor cloud modernization programs. You won't manage headcount - you'll own the technical direction: the target-state architecture, the standards multiple teams build against, and the confidence of senior stakeholders funding the work. The engineers around you write most of the code; you shape it, review it, and write the parts that set the pattern.

What You Bring

Must-Have

• 10+ years professional software/platform engineering experience with real senior technical lead accountability on complex, multi-vendor cloud programs
• Deep AWS hands-on: Lambda, Step Functions, ECS Fargate, API Gateway, DynamoDB, S3, EventBridge, Bedrock - enough to be challenged on it and hold the room
• Proven modernization track record: legacy systems converted into event-driven and agentic architectures
• Strong code review depth across Python, Node.js/JavaScript, and Terraform - design-level feedback, not surface commentary
• REST and GraphQL API design - able to catch integration problems before development starts
• Spec rigor - critically evaluating FRDs, BRDs, and functional specs and converting them into executable platform deliverables
• Executive presence: proven track record engaging VP-level and above, in person
• Offshore and partner vendor management within large delivery programs
• Architecture governance experience - ARB or equivalent
• Strong written output: ADRs, decision logs, design docs, and status reports that hold under scrutiny
• Agile delivery leadership across multi-team programs (Scrum or Kanban)
• Bachelor's in CS, Software Engineering, or equivalent experience

Bonus Points

• Regulated industry experience - life sciences, clinical, healthcare, or financial services (GxP/validated systems a plus)
• Scientific/statistical computing familiarity: SAS, R, statistical pipelines, analysis-ready data
• GenAI and LLM application patterns - agentic workflows, retrieval, tool use, guardrails, evaluation
• AWS Professional certifications (Solutions Architect or DevOps Engineer); CSM
• Prior consulting or professional services background on enterprise engagements
• Experience standing up a delivery practice or program from scratch

What You'll Do

You'll own the target-state architecture across event-driven and agentic designs built on AWS - making and defending service selection, integration patterns, and design tradeoff decisions grounded in distributed systems fundamentals and the AWS Well-Architected Framework. Where it counts, you stay hands-on: reference implementations, architecture spikes, and the hardest problems your teams surface.

Across multiple delivery teams, partner vendors, and offshore groups, you'll set the engineering standards everyone builds against - patterns, contracts, testing expectations, and definition of done. You'll hold vendor output to the same bar as internal work and escalate credibly when it falls short.

On the stakeholder side, you'll engage VP-level clients directly as the technical voice of the program - translating between business and engineering audiences without losing precision in either direction, and producing the written record the program runs on.
