The ideal candidate brings strong engineering fundamentals, a product mindset, and the ability to independently solve complex technical problems in a collaborative, fast-paced environment.

Requirements

Bachelor's degree in computer science, Software Engineering, or equivalent practical experience, with 5+ years of hands-on, production-grade full-stack experience.
Strong frontend (ReactJS, TypeScript, JavaScript, hooks, reusable UI components) and backend (Go, Java, Python, or Node.js) development building APIs, services, and integrations (REST, gRPC, Thrift; Koa).
Solid understanding of system design, distributed systems, scalability, and performance optimization.
Working knowledge of relational (PostgreSQL, MySQL, Aurora, RDS) and non-relational (MongoDB, DocumentDB, DynamoDB, Redis) databases.
Hands-on AWS experience (ECS, Lambda, API Gateway, S3, CloudWatch, and similar services).
Experience with Docker, CI/CD (CircleCI), Terraform, and modern DevOps practices.
Experience writing unit, integration, and UI tests (Jest, Cypress, or similar).
Agile/Scrum delivery experience with strong ownership across distributed, cross-time-zone teams.
Familiarity with AI-assisted engineering tools (Gemini, Claude Code, GitHub Copilot) to boost productivity and code quality.
Proven ability to independently own and deliver complex technical initiatives.
Experience collaborating effectively within distributed and agile teams.
Strong analytical and problem-solving skills.
Excellent communication and stakeholder management abilities.
Experience mentoring engineers and driving technical excellence across teams.

Build and enhance RESTful APIs, gRPC/Thrift integrations, microservices, and distributed systems supporting business-critical workflows.
Participate in architecture reviews, technical design discussions, and code reviews; drive engineering practices across coding standards, automated testing (incl. Cypress UI regression), security, observability, and CI/CD.
Troubleshoot complex production issues and drive improvements to reliability, performance, and user experience.
Contribute to cloud infrastructure and deployment automation across AWS-based environments.
Mentor junior and mid-level engineers, and collaborate closely with product managers, architects, and designers to deliver high-quality software.
Communicate technical decisions, risks, and trade-offs clearly to stakeholders and team members.
