Your Next Challenge
Our Technology Journey:
We are at a defining moment in our technology transformation. Having built strong foundations in traditional infrastructure and networking, we are now accelerating towards a cloud‑native, highly automated, and reliability‑first engineering culture. This shift represents more than technical evolution, it is a strategic redesign of how we architect platforms, deliver services, and scale with the expectations of a modern financial institution.
We are at a defining moment in our technology transformation. Having built strong foundations in traditional infrastructure and networking, we are now accelerating towards a cloud‑native, highly automated, and reliability‑first engineering culture. This shift represents more than technical evolution, it is a strategic redesign of how we architect platforms, deliver services, and scale with the expectations of a modern financial institution.
As we modernise legacy systems, embed DevOps and observability best practice, strengthen operational resilience, and move decisively into cloud native patterns, we are laying the groundwork for our next decade of growth across payments and FX.
Why this matters for you
Joining our team at this stage means shaping the destination, not simply following the roadmap. You will:
- Lead the evolution from legacy IaaS to performant, resilient, cloud‑native services.
- Define and embed the reliability, observability, and automation practices that guide how engineering teams design and operate platforms.
- Act as a coach, engineer, strategist, and technical leader across multiple teams and functions.
- Work deeply across technology, product, sales, legal, and operations to translate reliability into measurable business value.
This transformation is rich with complex systems challenges, and equally rich with opportunities for innovation, influence, and engineering excellence.
Key Responsibilities:
Reliability Engineering & Observability
- Define and maintain SLOs/SLIs and error budgets for critical services.
- Design, build and enhance observability tooling and pipelines (metrics, logs, traces) used by engineering teams.
- Create and maintain dashboards for golden signals.
- Develop and update incident runbooks; lead post-incident reviews.
- Approves SLO/SLI targets and error budgets for Tier-1 services
- Implement anomaly detection and predictive monitoring.
- Perform capacity forecasting for cloud and IaaS workloads.
- Tune systems for throughput and latency improvements.
- Use telemetry to identify and resolve performance bottlenecks.
- Automate backup, restore, and failover processes.
- Validate RTO/RPO targets through regular DR tests.
- Design and execute chaos engineering experiments.
- Enhance self-healing and rollback/roll-forward automation.
- Acts as incident commander during SEV-1/SEV-2 events; authorises rollback/run decisions.
- Drive root cause analysis and implement permanent fixes.
- Eliminate toil via scripting and automation.
- Standardise reliability patterns across teams.
- Map dependencies for important business services.
- Conduct severe-but-plausible scenario tests.
- Supporting legal in drafting precise, customer oriented SLAs informed by real operational behaviour.
- Signs off on resilience test results and impact tolerance evidence.
- Document and evidence compliance with impact tolerances.
- Support third-party resilience assessments.
- Identify problematic platform components impacting scale/resilience.
- Prioritises reliability-driven refactors and approves migration patterns.
- Engineer replacements using modern patterns (e.g., containerisation, service mesh).
- Lead migration strategies with measurable reliability outcomes.
