The Role

Nium is looking for a Senior Manager, Site Reliability Engineering to lead the teams responsible for the availability, performance, scalability, and operational excellence of our global payments platform. This is a hands-on leadership role: you will build and grow a team of SREs, define the reliability roadmap, and partner closely with product engineering, security, and infrastructure teams to ensure Niums systems meet the always-on expectations of a regulated financial platform operating across 100+ markets.

You will own incident management, observability, capacity planning, and production readiness practices, while championing a culture of blameless postmortems, proactive risk reduction, and engineering-driven automation. This role sits at the intersection of engineering leadership and operational rigor, and reports into Niums engineering leadership.

Responsibilities

- Lead, mentor, and grow a team of SREs and reliability engineers across multiple time zones, setting explicit goals, career paths, and performance expectations.

- Own Niums reliability strategy - defining and driving SLIs/SLOs/error budgets across critical payment, card issuance, and compliance services.

- Drive incident management end-to-end: on-call structure, escalation paths, major incident response, and blameless postmortems that produce durable fixes, not just tickets.

- Partner with product engineering leaders to embed reliability, scalability, and operational readiness into the software development lifecycle from design through launch.

- Build and scale observability (metrics, logging, tracing, alerting) so that issues are detected and diagnosed before they impact customers or partner banks.

- Lead capacity planning and performance engineering for systems processing high-volume, real-time financial transactions across a global, multi-region infrastructure.

- Champion automation and self-healing systems to reduce toil, eliminate manual runbooks,



and improve mean-time-to-detect and mean-time-to-resolve.

- Own disaster recovery, business continuity, and chaos engineering practices, running regular game days to validate resilience assumptions.

- Collaborate with Security and Compliance teams to ensure infrastructure practices meet regulatory and audit requirements (PCI-DSS, SOC 2, ISO 27001, and regional financial regulations).

- Manage the reliability budget: tooling investments, cloud cost/performance trade-offs, and staffing plans, in partnership with finance and engineering leadership.

- Represent SRE in executive reviews, translating technical risk and system health into business-relevant reporting for leadership and the board.

- Establish and continuously refine production readiness reviews, runbooks, and operational standards across all engineering teams.

Requirements

- 10+ years of experience in software engineering, infrastructure, or site reliability engineering, with 4+ years in a people-management or technical leadership role leading SRE/DevOps/Infrastructure teams.

- Proven track record operating and scaling production systems for a high-availability, transaction-heavy platform - fintech, payments, banking, or e-commerce experience strongly preferred.

- Deep hands-on expertise with cloud infrastructure (AWS) Kubernetes, container orchestration, and infrastructure-as-code (Terraform, CloudFormation, or similar).

- Strong background in observability stacks (Prometheus, Grafana, Datadog, ELK/OpenSearch, or equivalent) and building alerting that reduces noise while catching real issues.

- Demonstrated experience defining and operationalizing SLOs/error budgets, and using them to drive engineering prioritization.
