Staff Platform Development Engineer

About the role

The Team / Who We Are We build and operate the infrastructure backbone that powers one of the financial services industry's most demanding SaaS platforms. Our Platform Engineering team sits at the intersection of DevOps, private and public cloud infrastructure, and financial technology - ensuring that mission-critical investment accounting, portfolio analytics, and data connectivity services run with carrier-grade reliability, 24/7, for over a thousand of the largest hedge funds, asset managers, family offices, insurers and corporations. We move fast, take ownership, and operate with a low-ego, high-output mentality. Engineers here have real impact - not just tickets to close. We've scaled significantly over the last several years, expanding our global footprint, deepening our cloud-native infrastructure, and modernizing the financial data pipelines that connect our platform to custodians, prime brokers, data vendors, and counterparties. If you want to work on problems that actually matter in FinTech - at serious scale - you've found the right team. What We Need We're looking for a seasoned Staff Platform Engineer who can own the full stack of infrastructure concerns - from bare metal and virtualization layers up through container orchestration, observability, and CI/CD pipelines. This isn't a ticket-taker role. You'll be a principal contributor shaping how we architect, automate, and scale the platform that underpins our clients' most sensitive financial operations. You'll work closely with software engineering, security, data operations, and client connectivity teams. You'll also serve as a senior escalation point for complex infrastructure and platform issues - including those that touch financial data feeds, custody integrations, and low-latency market data ingestion. Experience operating in a regulated financial environment is a meaningful advantage here. Primary Responsibilities In this role, you'll own and contribute to the following: Design, build, and maintain scalable, highly available infrastructure supporting a multi-tenant financial SaaS platform - including on-premises systems, hybrid cloud environments (AWS), and co-location data centers. Lead platform automation efforts using infrastructure-as-code (IaC) tooling such as Harbor, Terraform, Ansible, or Salt - driving consistency, repeatability, and auditability across all environments. Own and evolve our container orchestration strategy - including Kubernetes cluster operations, workload scheduling, resource governance, and service mesh configuration. Architect and operate CI/CD pipelines and deployment automation in collaboration with software engineering and release management teams; drive DevOps best practices across the SDLC. Build and maintain a comprehensive observability stack - including metrics (Prometheus/Grafana), log aggregation (Elastic Stack / CheckMk), and distributed tracing - with a focus on financial platform SLIs -> SLOs -> OLAs -> SLAs. Support and optimize financial data connectivity infrastructure, including market data feed handlers, custodian data ingestion pipelines, FIX/SWIFT/SFTP-based integrations, and third-party data vendor connectivity. Provide Tier 2/3 escalation support for platform-level incidents; lead root cause analysis and drive permanent resolution of systemic reliability issues. Perform capacity planning, performance engineering, and infrastructure cost optimization across compute, storage, and network layers. Partner with the Security and Compliance teams to ensure infrastructure adherence to SOC 2 Type II, ISO 27001, and applicable financial industry regulatory requirements. Evaluate emerging technologies and vendor solutions; make architectural recommendations grounded in operational maturity and business impact. Mentor junior and mid-level engineers; contribute to team documentation, runbooks, and internal knowledge base standards. You Are a Great Fit If You take ownership without being asked. You're the engineer who reads the post-mortem, implements the fix, and then writes the runbook so it doesn't happen again. You're comfortable in ambiguity, thrive in a collaborative environment, and you have a bias for action over analysis paralysis. You care about the craft - clean automation, thoughtful architecture, solid documentation - and you know that in financial services, the details really do matter. You've probably dealt with the unique constraints of regulated infrastructure - where uptime commitments, audit trails, and data integrity requirements add a layer of complexity that most pure-tech shops never face. You don't find that frustrating; you find it interesting. You also probably like good food - we're right inside the Revival Food Hall. Job Qualifications To be successful in this role, you should bring the following: Required 7+ years of experience in platform engineering, Linux systems administration, or DevOps/SRE roles - with at least 3 years in a financial services or FinTech
