Staff Infrastructure Engineer

As a Staff Infrastructure Engineer at Flow Traders, you will define the long-term technical architecture and engineering standards across our enterprise systems estate, including identity, endpoints, compute, virtualization, operating systems, storage, databases, and the platforms beneath our enterprise SaaS. Reporting to the Global Head of IT, you act as the senior technical authority and mentor to our engineers, driving automation, engineering best practices, and modernization. This is a hands-on, senior individual contributor role focused on shaping technical direction and building, not managing a team.

What you'll do

• Define and own the long-term architecture and engineering standards for Enterprise Systems, covering identity, endpoints, compute, storage, databases, and the foundations supporting enterprise SaaS platforms
• Act as the senior technical authority, mentoring engineers and driving high-quality architecture and design decisions
• Translate complex business and technology challenges into clear technical roadmaps and scalable solutions
• Lead modernization across identity, endpoint management, compute, and workplace technologies, and make on-premise versus cloud decisions on merit
• Drive automation and self-service capabilities to improve efficiency, resilience, and user experience
• Rationalize and optimize the technology landscape, responsibly retiring legacy systems in favour of modern, cost-effective solutions
• Own the underlying platforms that support enterprise applications, including SSO, provisioning, integrations, and data flows
• Champion engineering excellence through rigorous testing, validation, and lab-first deployment practices

What you bring

• 10+ years of senior enterprise infrastructure engineering experience at Staff, Principal, or Technical Lead level
• Deep expertise in identity and access management, cloud platforms, virtualization, and enterprise infrastructure
• Proven success leading cloud migrations, legacy platform retirements, and large-scale modernization initiatives
• Strong architectural judgment with a vendor-neutral approach to cloud and platform decisions, choosing the right target on merit rather than by default
• Experience integrating enterprise SaaS platforms through SSO, automated provisioning, APIs, and secure connectivity
• Hands-on experience with automation, Infrastructure as Code, and applying AI to improve operations
• Strong stakeholder management skills, with the ability to influence and drive cross-functional alignment
• The ability to mentor engineers, raise engineering standards, and thrive as a hands-on individual contributor in a global, multi-region environment

What we offer

• Flow Academy and opportunities to attend domain-related conferences
• Daily catered lunch, great coffee, and a fully stocked kitchen and snack bar
• In-house bar and lounge with arcade, table tennis, billiards, and game consoles
• Company boat
• In-house gym and sessions with our nutritionist or personal trainer
• Bi-weekly massages
• Annual company trip and a variety of events throughout the year
