Job Description:

Are you excited to influence technical direction across teams while still contributing hands‑on to complex, high‑impact engineering challenges? Do you want to shape domain architecture, mentor senior engineers, and connect technical decisions to real customer and business outcomes? About our Team: RX Global aims to create unforgettable experiences for attendees and exhibitors through organizing events. Innovation, creativity, and collaboration drive the company to offer exceptional services to clients. About the Role: As a Principal Engineer, you will help teams do their best work by improving engineering practices, reducing delivery risk, and fostering a culture of trust, learning, and high standards. You will lead through influence, collaborate across disciplines, and connect technical decisions to meaningful customer and business outcomes. This role combines technical leadership, hands-on contribution, and partnership with product, engineering, and architecture leaders. We value different career paths and welcome candidates who bring varied experiences and perspectives.

Job Responsibility:

Own the technical direction and long-term health of a critical business domain spanning multiple delivery teams
Act as the senior hands-on technical authority, setting a high bar for architecture, security, reliability, and maintainability

Drive sound architectural decisions and trade-offs across scalability, resilience, cost, and time-to-market
Define and evolve domain architecture, service boundaries, and integration patterns that enable team autonomy
Influence and align teams through strong engineering judgement, data, and clear communication rather than authority
Lead complex technical initiatives including system modernisation, risk reduction, and legacy decommissioning
Raise the engineering bar by mentoring senior engineers and emerging technical leaders
Take hands-on ownership of high-risk or high-impact technical work when it matters most
Champion operational excellence, including reliability, observability, incident learning, and cloud cost optimisation

Requirements:

Deep expertise in software architecture and distributed systems design
Strong engineering judgement with the ability to clearly explain and balance complex technical trade-offs
Experience designing and evolving APIs, events, and data ownership in large-scale systems
Track record of modernising legacy systems and moving toward cloud-native architectures
Strong experience building secure, scalable, and resilient cloud-based solutions (AWS or equivalent)
Comfort working in a polyglot technology environment and selecting fit-for-purpose tools
Experience influencing architectural change and driving alignment across engineering and product partners
Solid understanding of testing strategies, CI/CD, and operational reliability practices
