Objectives

We are looking for a solution-driven Senior Backend Engineer / Backend Lead to join PMAX Tech & Data, responsible for owning backend architecture and execution for key platform modules, building scalable and secure systems, raising engineering quality, and helping modernise legacy services. You will be hands-on in delivery while also leading technical direction—covering the full lifecycle from discovery and design to implementation, release, observability, and continuous improvement.

Job Description

1) Technical Ownership & Delivery Leadership

  • Own end-to-end delivery for assigned backend domains (services, APIs, integrations), ensuring quality, performance, and reliability.
  • Drive technical planning: break down requirements, propose implementation options, estimate effort, identify risks, and align milestones with stakeholders.
  • Participate in sprint ceremonies and proactively shape backlog quality (testability, acceptance criteria, dependencies, non-functional requirements).

2) Backend Architecture & API Engineering

  • Design and develop scalable backend services and APIs (REST/GraphQL as applicable), ensuring clean architecture and maintainability.
  • Define and maintain backend standards: service patterns, error handling, logging, versioning, and backwards compatibility.
  • Implement core platform capabilities: RBAC/permissions, approval workflows, audit logs, notifications, job scheduling, and multi-tenant considerations (where applicable).

3) Performance, Reliability & Observability

  • Profile and optimise bottlenecks across application and database layers (query optimisation, caching, async processing, pagination, indexing).
  • Design for reliability: idempotency, retries, dead-letter strategies, graceful degradation, and rate limiting.
  • Establish observability practices: structured logs, metrics, tracing, alerting, and operational dashboards; contribute to incident response and post-mortems.

4) Data Integration, Migration & Platform Modernisation

  • Integrate multiple data sources and systems into a coherent backend (Ads platforms, CRM, internal tools, analytics pipelines).
  • Own data migration and transformation initiatives: schema evolution, backfills, scripting, and reconciliation.
  • Modernise legacy applications/services: refactor or re-architect modules with minimal business disruption, focusing on long-term scalability.

5) Engineering Excellence & Mentorship

  • Write and enforce high-quality code practices: code reviews, testing strategy (unit/integration), CI/CD hygiene, and release readiness checklists.
  • Provide technical guidance and mentorship to junior engineers; raise the bar on documentation and knowledge sharing.
  • Contribute to engineering culture: pragmatic best practices, reusable libraries, design templates, and runbooks.

6) Security & Compliance Fundamentals

  • Apply secure coding practices and ensure proper secrets management, access control, and auditability.
  • Ensure backend designs align with privacy and data governance requirements (as relevant to PMAX client/partner data).

Job Requirements

Skill & Qualifications

  • Degree in Information Technology or related field (or equivalent practical experience).
  • 3–5 years in Backend Engineering roles with proven track record shipping production systems.
  • Strong proficiency in NodeJS (preferred) or strong backend experience in Python/Ruby/Java/Go/PHP with ability to ramp quickly on NodeJS.
  • Strong knowledge of backend fundamentals: system design, software architecture, design patterns, clean code, and engineering best practices.
  • Solid database expertise: data modelling, schema design, and performance tuning (SQL required; NoSQL is a plus).
  • Experience designing and operating APIs at scale: authentication/authorisation, versioning, error contracts, rate limiting, and reliability patterns.
  • Experience with cloud-based technologies and modern engineering practices (Git workflow, CI/CD, testing discipline, monitoring/alerting).
  • Strong communication skills: able to explain technical concepts to non-technical business leaders and influence trade-offs.
  • Strong strategic mindset and problem-solving skills; ability to operate under ambiguity and bring clarity.

Plus / Advantage

  • Experience with event-driven architecture, queues, background workers, scheduling systems.
  • Experience with observability stacks (APM, metrics, logs), SLO/SLI thinking, and incident management.
  • Experience integrating with marketing/ads ecosystems (Meta, Google, TikTok, Shopee, Zalo) or martech stacks is a strong advantage.
  • Familiarity with data pipelines, analytics instrumentation, and metric correctness is a plus.
  • Prior experience as a technical lead for a small squad or mentoring juniors.

Mindset & Soft Skills

  • Ownership and accountability for outcomes (not only tasks).
  • Strong collaboration; able to challenge requirements constructively and propose better solutions.
  • Comfortable operating in a fast-paced environment with ambiguity; disciplined in clarifying assumptions early.
  • Curious, proactive, and continuously learning mindset.
  • Comfortable exploring and adopting AI-assisted development tools (e.g., code copilots, test/documentation assistants) to improve productivity and quality, with strong discipline on verification, security, and correctness.
