Job description

Build Scalable Systems That Power the Future of Finance

At BJAK, we’re building intelligent infrastructure to transform how insurance and financial services operate at scale across Southeast Asia. As we grow rapidly, our systems must be secure, reliable, and able to handle millions of users without compromise.

We’re looking for a Backend Software Engineer (Node.js) to join our engineering team in Malaysia and take ownership of critical backend services - from APIs and architecture to performance optimization and deployment.

This is a hands‑on, high‑impact role for someone who thrives on building reliable systems, writing clean code, and solving tough backend challenges. You’ll work closely with product, data, and frontend teams to bring scalable solutions to life, fast.

This role is based in Malaysia with a hybrid work arrangement.

Why This Role Matters

• Power mission‑critical platforms that serve millions of users across Southeast Asia.

• Own and optimize high‑performance backend systems that impact real‑time financial decision‑making.

• Enable rapid product development through reliable infrastructure and scalable APIs.

• Be part of a fast‑moving team that ships quality work and scales with urgency.

What You’ll Do

• Design, build, and maintain robust backend services and APIs using Node.js and modern frameworks (e.g., NestJS, ExpressJS, GraphQL).

• Collaborate with cross‑functional teams to support new features and drive technical decisions.

• Ensure production systems are scalable, stable, and secure, with strong monitoring and alerting in place.

• Refactor legacy systems for performance, maintainability, and clarity.

• Lead and participate in code reviews, design discussions, and knowledge sharing.

• Support integration, deployment, and post‑release debugging to ensure system reliability.

• Help define and uphold backend engineering best practices across the team.

You’ll Thrive Here If You...

• Care deeply about code quality, performance, and clean architecture.

• Take initiative to solve problems independently and without being micromanaged.

• Are comfortable in a fast‑moving environment where priorities shift quickly.

• Have strong attention to detail, but don’t let it stop you from shipping.

• Enjoy collaborating with product, data, and design teams to build real solutions.

• Are self‑motivated, low‑ego, and focused on outcomes.

What You Bring

• Bachelor’s degree in Computer Science, Software Engineering, or a related technical field.

• 3+ years of full‑time experience in backend engineering roles.

• Strong proficiency in Node.js, with practical experience using frameworks like NestJS, ExpressJS, or GraphQL.

• Solid knowledge of databases such as MongoDB, MySQL, or similar.

• Familiarity with tools like Postman, Selenium, Cypress, or Puppeteer.

• A strong grasp of data structures, algorithms, and system design.

• Clear, professional communication and the ability to work effectively in a hybrid team.

• Based in Malaysia and open to hybrid work.

Nice to Have

• Experience deploying services to AWS, GCP, or other cloud environments.

• Familiarity with Docker, CI/CD pipelines, or Infrastructure as Code practices.

• Exposure to Test‑Driven Development (TDD) or Behavior‑Driven Development (BDD).

• Portfolio or GitHub repositories that showcase your technical capabilities.

• Prior experience working in a high‑growth or startup environment.

Our Team & Culture

We’re a lean, high‑performance team that moves fast and holds a high bar. Titles don’t matter here - output, ownership, and problem‑solving do. Everyone is expected to contribute, improve the system, and take initiative.

We reward people who build with clarity and move with urgency. We value engineers who take full ownership of their work, think end‑to‑end, and never stop learning.

If you’re hungry to grow, enjoy solving challenging technical problems, and want to build something that matters, you’ll fit right in.

What You’ll Get

• Competitive salary with performance‑based incentives.

• Hybrid work flexibility - remote convenience with in‑office collaboration.

• Autonomy and ownership from day one.

• Exposure to large‑scale, production‑grade systems used by millions.

• Fast‑paced growth environment with strong engineering mentorship.

• A team that values impact, speed, and continuous improvement.
