Systems Engineer – Next-Gen Telecom Platforms (MVNE/BSS)


## Why This Role Matters

Imagine working at the intersection of a disruptive telecom operator and a massive global digital ecosystem.

Having successfully launched our initial core platform, we are entering an explosive growth phase. Our team bridges the gap between complex business vision and high-performance engineering. As a Systems Engineer for MVNE Services, you won't just maintain systems—you will architect the onboarding framework for future MVNO partners and directly influence how millions of users experience mobile connectivity.

Career Trajectory: This is a high-growth role designed for an ambitious engineer. You will be explicitly groomed to step up and lead a team of Business Analysts as our business expands.


## What You Will Do

As the vital bridge between Business and Engineering, you will own the end-to-end lifecycle of our Business Support Systems (BSS) and MVNE services.

1. Requirement Engineering & Solution Architecture

  • Translate Vision to Reality: Deconstruct complex business demands into precise BSS system requirements and technical Change Requests (CRs).
  • Visualize Workflows: Design technical blueprints, process flows, and sequence diagrams to align cross-functional teams.
  • Uphold Industry Standards: Partner with Design, Dev, and QA teams to ensure all solutions comply with global Telecom Industry BSS standards.

2. Strategic MVNO Onboarding

  • Drive Integration: Lead the technical planning, scoping, and onboarding of next-generation MVNO partners onto our BSS platform.
  • Stakeholder Management: Coordinate alignment across internal and external stakeholders regarding timelines, technical deliverables, and risk mitigation strategies.

3. Quality Assurance & Release Governance

  • Own the Release: Guard the production environment by reviewing SIT, UAT, and production sanity test cases.
  • Technical Support: Act as the technical escalation point for Operations and QA teams, ensuring rapid closure of system anomalies and supporting robust security testing.


## Who You Are

We are looking for a proactive technical professional who thrives in a fast-paced, startup-like environment but wants the stability and reach of a global tech giant.

  • The Tech-Savvy Communicator: You can talk APIs and architecture with developers, and business value with stakeholders.
  • The Problem Solver: You look at a complex business bottleneck and naturally map out a clean sequence diagram to fix it.
  • The Growth Mindset: You are eager to master BSS/MVNE architectures and possess the ambition to transition into a leadership/management role.


## What We Offer

  • Global Exposure: Work with diverse, brilliant engineering minds across Japan, India, China, and Singapore.
  • Disruptive Innovation: Be a part of a company that has fundamentally changed the economics of the telecom industry.
