Lead Full Stack Engineer

About the role

MegazoneCloud is seeking a Lead Software Engineer to lead technical direction on complex, multi-vendor cloud programs that modernize legacy applications and manual processes into agentic, event-driven architectures on AWS. This is a hands-on technical leadership role, not a people-management one.

Responsibilities

• Own the target-state architecture for the program: event-driven and agentic designs built on Lambda, Step Functions, ECS Fargate, API Gateway, DynamoDB, S3, EventBridge, and Bedrock.
• Make and defend service selection, integration pattern, and design tradeoff decisions, grounded in distributed systems fundamentals and the AWS Well-Architected Framework.
• Set the engineering standards multiple teams deliver against — patterns, contracts, testing expectations, and the definition of done.
• Stay hands-on where it counts: reference implementations, architecture spikes, and the hardest technical problems your teams surface.
• Review code and technical artifacts — Python, Node.js/JavaScript, Terraform — with enough depth to give meaningful design-level feedback, not surface commentary.
• Contribute to and review REST and GraphQL API contracts, assessing consistency and completeness and identifying integration issues before development begins.
• Critically review FRDs, BRDs, and functional specifications — surfacing gaps, ambiguities, and technically infeasible requirements early, and translating business requirements into precise platform deliverables.
• Participate in architecture governance — ARB or equivalent — as the person who prepares the submission and answers for it.
• Engage senior client stakeholders at VP level and above, face to face, as the technical voice of the program.
• Translate between business and IT audiences at varying levels of seniority without losing precision in either direction.
• Produce the written record the program runs on: architecture decision records, decision logs, design documentation, and status reporting that an executive can act on.
• Coordinate technical delivery across multiple teams, partner vendors, offshore development groups, and specialist analytics firms.
• Hold vendor output to the same technical bar as internal work, and escalate credibly when it falls short.
• Run the program's technical cadence within an Agile delivery model — Scrum or Kanban — across teams that do not all report to the same place.

Requirements

Must be authorized to work in the United States. Visa sponsorship and relocation are not provided.

Qualifications

• 8+ years of professional software or platform engineering experience, including demonstrated time as the senior technical lead on complex, multi-vendor cloud programs.
• Formal title is not required, but the accountability must have been real.
• AWS depth. Solid hands-on knowledge of Step Functions, Lambda, ECS Fargate, API Gateway, DynamoDB, S3, EventBridge, and Bedrock — enough to recommend the right services and architectures for a given set of requirements and to be challenged on it.
• Modernization track record. Proven delivery modernizing legacy applications and processes into event-driven, and increasingly agentic, architectures.
• Code review depth. Comfortable reading Python, Node.js/JavaScript, and Terraform well enough to provide design-level feedback and assess system architecture.
• API design. Able to contribute to and review REST or GraphQL contracts and catch integration problems before development starts.
• Specification rigor. Demonstrated ability to critically evaluate FRDs, BRDs, and functional specifications and convert them into platform deliverables engineers can execute against.
• Executive presence. A track record engaging business and technical stakeholders at VP level and above in person, and holding the room.
• Vendor and partner management. Experience managing offshore development teams, specialist firms, or partner delivery relationships within a larger program.
• Architecture governance. Familiarity with solution architecture and design review processes, including contributing to an ARB or equivalent.
• Communication. Strong written and verbal skills — clear documentation, decision logs, ADRs, and status reports that hold up under scrutiny.
• Agile delivery. Experience running or leading technical delivery across multi-team programs using Scrum or Kanban.
• Educational background. Bachelor's degree in Computer Science, Software Engineering, or equivalent practical experience.
• Bonus points. Experience in regulated environments — life sciences, clinical, healthcare, or financial services — including validated or GxP-adjacent systems.
• Familiarity with scientific or statistical computing environments and the workflows around them: SAS, R, statistical programming pipelines, and analysis-ready data and reporting outputs.
• Hands-on experience with GenAI and LLM application patterns — agentic workflows, retrieval, tool use, guardrails, and evaluation.
• AWS certifications at Professional level (Solutions Architect – Professional or DevOps Engineer – Professional); Certified ScrumMaster.
• Prior consulting or professional services experience on enterprise engagements.
• Experience standing up a delivery capability, practice, or program from scratch.

Skills

• Technical leadership and architectural design skills.
• Strong communication and stakeholder engagement skills.
• Experience with AWS services and frameworks.
• Ability to translate business requirements into technical solutions.
• Experience with REST and GraphQL APIs.
• Expertise in code review and API contract review.
• Experience with agile methodologies and project management.
• Knowledge of regulatory compliance and industry standards.
