We are building a new marketplace platform to modernize how we process orders across multiple sale channels. The platform replaces a legacy monolithic system with purpose-built services for channel integration and order fulfillment.As the Senior Software Engineeer, you will own the technical direction and delivery of this platform from day one. You will lead a dedicated build team through the initial delivery, then evolve into leading two permanent squads as the team converges with the existing marketplace team.This is a dual-track role: you will drive a greenfield platform build while maintaining oversight of a legacy system during a parallel migration period. You will also pioneer AI-native development practices, using AI pair programming as a core part of the team’s workflow.What You'll DoTechnical Leadership

Design and review event-driven distributed systems across platform services
Define API contracts, messaging topology (SNS/SQS), and database schemas (PostgreSQL)
Establish architecture patterns: adapter-based channel integration, state machine-driven fulfillment workflows, DLQ handling
Evaluate and review AI-generated code critically — ensuring quality, security, and maintainability
Own technical decision-making for the platform, balancing speed with long-term maintainability

Delivery & Process

Lead end-to-end platform delivery from design through production go-live
Run tight sprint cadences with clear goals and retrospectives
Establish code review standards, CI/CD pipelines, and deployment practices
Set up on-call rotations, incident response processes, and runbook documentation
Coordinate knowledge transfer from the existing team during the build phase

People & Growth

Build and lead the new platform team from onboarding through production delivery
After go-live, lead the convergence of the new and existing teams into two purpose-built squads
Mentor existing .NET developers transitioning to the TypeScript stack
Span both squads long-term, providing architectural oversight across the domain

RequirementsMust Have

6+ years of backend engineering experience, with 2+ years in a tech lead or senior architect role
Strong proficiency in TypeScript and Node.js
Deep experience with event-driven architectures: message queues (SQS, SNS, Kafka), async workflows, idempotency patterns
Production experience with AWS services: EKS/Kubernetes, Aurora/RDS (PostgreSQL), ElastiCache (Redis), SQS/SNS
Experience designing and operating distributed systems with proper observability (structured logging, distributed tracing, dashboards)
Proven ability to run agile delivery: sprint planning, backlog management, retrospectives
Strong code review culture — can review PRs for correctness, security, and design quality

Nice to Have

Familiarity with .NET 6 / .NET Framework (for legacy oversight during migration)
Experience with AI pair programming tools (Copilot, Claude, Cursor) and AI-native development workflows
Experience migrating systems from monolith to microservices
Contract testing experience (Pact or similar)
Experience integrating with third-party marketplace APIs (e.g., Shopee, Lazada, Grab, or similar)
