Full Stack Engineer
Location: Singapore, Remote (you may need to come to the office 1-2x a month on a needs basis)
Type:
Contract / Outsourced , Full-time hours
About the Role We're looking for a Full Stack Engineer to help build and scale AI-powered software products and automation solutions used by enterprise clients. You'll work on a modern development platform that supports multiple products and projects, with a strong focus on rapid product development, automation, and scalable architecture.
The core platform is built on a NestJS backend and extended through custom modules covering authentication, billing, CRM, task management, and document workflows. The technology stack includes TypeScript/NestJS, Python service workers, and AWS infrastructure (Aurora PostgreSQL, SSM, Secrets Manager, and CDK).
In this role, you'll own new features end-to-end—from API design and backend services to dashboard implementation and deployment. You'll work across both the core platform and a variety of active product initiatives and client-facing projects, helping shape technical decisions and deliver impactful solutions.
What You'll Own Backend Extend the NestJS core and custom module system Write Prisma migrations against Aurora Serverless v2 Build and harden API endpoints: DTO validation, auth guards, rate limiting, input sanitization Own notification dispatch pipelines (email, SMS, voice) Extend the billing ledger: usage caps, per-feature cost tracking, period management, reconciliation
Infrastructure & Security Operate AWS: CDK stacks (VPC, Aurora, Redis, S3 with KMS CMK, CloudTrail, GuardDuty, SSM session logging) Identify and close attack surfaces: auth bypass paths, over-permissioned roles, unvalidated inputs, insecure defaults
Dashboard / Frontend Work in iOS environments Manage Next.js App Router, Tailwind CSS across platforms Run QA processes Manage all support tickets / bug fixes across platforms
Required Experience 4+ years TypeScript: NestJS (or equivalent decorator-based framework), Prisma, REST API design, DTO validation, guard/interceptor patterns Python: async service workers; you can read and extend a data processing or inference loop AWS: IAM, Aurora PostgreSQL, SSM Session Manager, Secrets Manager, KMS, S3 PostgreSQL: real migrations, row-level security, comfortable with EXPLAIN ANALYZE System operations: ssh, rsync, launchd/systemd, debugging a remote production node without GUI tools Ability to own a task end-to-end with minimal hand-holding
Nice to Have AWS CDK (TypeScript constructs) Redis pub/sub or BullMQ Pgvector or any embedding / vector similarity work Apple Silicon / MLX or ONNX Runtime experience Next.js App Router, Tailwind CSS Experience deploying to physical on-premises hardware, not just cloud infrastructure Prior work on compliance-adjacent systems (FedRAMP, SOC 2, HIPAA, CJIS, or equivalent)
