Responsibilities

Build shared platform services, internal SDKs, and developer tooling that other teams adopt to multiply squad output
Partner with engineering leadership, product, and finance to identify, scope, and prioritise platform investments with clear business outcomes (uptime = revenue, deploy frequency = faster GTM)
Own Kafka clusters end-to-end including topic design, partition strategy, consumer lag management, schema evolution, and failure recovery at scale
Lead Redis patterns across the organization: cluster mode, pub/sub, distributed locks, eviction policies, and scripting for low-latency financial workloads
Drive DORA metrics practice including deploy frequency, lead time, change failure rate, and MTTR, turning data into quarterly engineering decisions
Define and enforce observability, alerting, service mesh, and on-call standards across all squads
Write RFCs and ADRs that the organization builds from
Lead the evaluation of open-source tooling versus custom builds
Embed audit trails, data residency, and PCI/SOC-aware patterns into platform design from day one
Grow mid and senior engineers through architecture reviews, pairing, and written craft

Requirements

8+ years in software engineering with at least 4 years in a platform, SRE, or infrastructure-focused role with clear evidence of building systems other teams depended on
Deep Kafka experience including partition strategy, consumer group design, exactly-once semantics, and failure recovery in production
Redis at scale including cluster mode, pub/sub, eviction policies, and distributed lock patterns
Strong proficiency in .NET (C#) and/or Python within high-throughput microservices architectures
Experience processing high-volume, low-latency financial transactions with the compliance requirements that come with them
DORA fluency with demonstrated ability to drive real engineering improvements and present results to leadership
Portfolio of internal platforms, SDKs, or shared libraries that other teams adopted and continued to use after you moved on
Fintech, payments, or regulated financial services background with understanding of what compliance boundaries mean for infrastructure decisions
