BACKEND ENGINEER

PIXELATE EVERYTHING; Subang Jaya; On-site; MYR 60,000 - 100,000; Full time

Job summary

PIXELATE EVERYTHING is seeking a backend engineer to design and build scalable microservices using Node.js/TypeScript and NestJS. You will define contracts, build REST APIs, and work with gRPC and queue-based messaging in a multi-tenant environment.

You will verify AI-generated code, write automated tests, and help keep CI pipelines green while collaborating across frontend, data, and QA teams.

Qualifications

• 2+ years of production experience with Node.js and TypeScript.
• Experience building REST APIs and using gRPC or a message queue.
• Daily use of AI coding assistants and the discipline to review and test their output.
• Git workflow and automated testing.

Responsibilities

• Design and build backend services and APIs; define contracts (OpenAPI, proto, Kafka events) before implementation so the front-end, data, and QA teams can start the same day.
• Own correctness on wallet, payment, and settlement paths: transactions, idempotency, concurrency.
• Integrate third-party partner APIs: authentication schemes, signatures, callbacks, reconciliation.
• Review AI-generated and peer code critically.
• Write and maintain automated tests; keep CI green.
• Debug production issues using logs, metrics, and error monitoring.
• Participate in sprint planning and give honest estimates.

Job description

We run a multi-tenant B2B platform: a dozen NestJS microservices behind gRPC and Kafka, PostgreSQL and Redis, deployed on AWS. Transaction volume is real-time and money-bearing. Our team uses AI coding tools heavily; you will spend more time designing, reviewing, and verifying than typing. We hire junior to senior into this role(preferably Mandarin for the China market project); level and package are set from the interview, not the CV.

Key Responsibilities

Design and build backend services and APIs; define contracts (OpenAPI, proto, Kafka events) before implementation so the front-end, data, and QA teams can start the same day.

Own correctness on wallet, payment, and settlement paths: transactions, idempotency, concurrency.

Integrate third-party partner APIs: authentication schemes, signatures, callbacks, reconciliation.

Review AI-generated and peer code critically.

Write and maintain automated tests; keep CI green.

Debug production issues using logs, metrics, and error monitoring.

Participate in sprint planning and give honest estimates.

Required Skills and Qualifications

2+ years with working experience with Node.js and TypeScript in production; NestJS or similar.

Has built REST APIs and consumed at least one of gRPC or a message queue.

Daily use of AI coding assistants, with the discipline to review and test their output rather than trust it.

Git, PR-based workflow, automated testing.

Nice to Have

Multi-tenant systems, row-level security, or wallet/ledger systems.

Kafka, Redis, AWS ECS, ClickHouse.

Third-party API integrations with signature-based auth.

Has worked in a team where AI tools produce a meaningful share of PRs (e.g. Claude Code, Codex, Cursor, Copilot).
