Job Summary

• We are looking for a highly skilled Senior Full Stack Engineer to design, build, and scale customer-facing technology platforms. This role requires strong hands-on expertise across frontend and backend engineering, with the ability to deliver end-to-end solutions using modern web technologies, cloud-native services, APIs, microservices, and distributed systems. 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.

• 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.

Required Skills & Experience

Technical Experience

• 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.

Professional Skills

• 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.

• Knowledge of Thrift or similar RPC frameworks for service-to-service communication.
• Experience working within monorepo environments and large-scale frontend codebases.
• Familiarity with Bazel build systems.
• Infrastructure-as-Code experience using Terraform, AWS CDK, or CloudFormation.
• Experience contributing to shared UI component libraries and enterprise design systems.
