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).
