Job description

The Senior Software Engineer is a hands‑on leader responsible for driving the full-stack design, development, and delivery of software solutions across one or more small, high-velocity engineering teams. This role operates above the Software Engineer level and blends deep engineering excellence with a modern AI-first mindset - including the ability to rapidly prototype with tools like Claude, Amazon Bedrock, and other GenAI platforms to accelerate team output and innovation.

Technical Leadership

Develop and review architectural and technical design decisions for features, services, or platforms.
Decompose epics and features into technical implementation plans with clear ownership.
Review and approve technical designs, code changes, and pull requests
Identify technical risks, dependencies, and trade-offs; propose mitigation strategies.
Drive root-cause analysis and resolution of complex production issues.

Full-Stack & Cross-Platform Development

Design, develop, test, and deploy full-stack applications across the core stack: React / TypeScript (web), Flutter / Dart (mobile & cross-platform), and Python / Node.js (backend).
Build and maintain scalable REST and GraphQL APIs using AWS API Gateway + Lambda.
Implement CI/CD pipelines, infrastructure-as-code (AWS CDK / SAM), and blue/green deployment strategies
Ensure production readiness through observability, automated testing, and monitoring
AWS Serverless Architecture (Core Competency).
Lead design and delivery of event-driven, serverless-first architectures on AWS. Deep hands-on expertise across:
Compute: Lambda, Step Functions
Data: DynamoDB (primary), S3, Aurora Serverless
Messaging & Events: SQS, SNS, EventBridge
API & Auth: API Gateway, Cognito, AppSync
Observability: CloudWatch, X-Ray
Infrastructure as Code: CDK, SAM, CloudFormation
Also responsible for cloud cost optimization, security posture, performance tuning, and defining serverless design patterns and guardrails for the team.

AI-Assisted Engineering & Rapid Prototyping

Rapidly prototype new product concepts using Claude, Amazon Bedrock, and other LLM/GenAI platforms.
Apply AI-assisted development tools to accelerate code generation, testing, documentation, and code review.
Evaluate AI-generated outputs for correctness, security, and production readiness.
Define team-level standards and best practices for AI tool adoption.
Demonstrate ability to ideate -> prototype -> validate -> ship in tight cycles to support fast-moving engineering teams.

Team Leadership

Serve as the technical anchor for a small, high-velocity scrum team - guiding direction, coaching engineers, and driving accountability.
Partner with Product Managers, Architects, and QA to align technical direction with organizational goals.
Mentor mid-level, and junior engineers on design, cloud practices, and AI tool usage.
Promote a culture of quality, continuous improvement, and learning.

Who You Are
