Senior/Lead Market Data Support Specialist

We’re a fast-growing market data technology provider partnering with leading investment banks, hedge funds, and trading firms to deliver high-performance data solutions. As demand for our platform accelerates, we’re expanding our client-facing technical team with a Lead/Senior Market Data Support Specialist who can operate at depth, command credibility with demanding stakeholders, and take ownership of complex, business-critical environments.

The Role

You’ll be the senior technical authority supporting our enterprise market data platform across multiple Tier-1 banking clients. This is a hands-on, high-visibility role where you’ll troubleshoot low-latency data issues, optimise distribution flows, and work closely with traders, quants, and infrastructure teams to ensure seamless delivery of real-time and reference data.

You’ll act as the escalation point for major incidents, lead root-cause analysis, and drive continuous improvement across client environments. You’ll also play a key role in onboarding new clients, shaping best practices, and influencing product direction based on real-world usage.

What You’ll Work On

• Supporting and optimising real-time market data distribution (e.g., feed handlers, ticker plants, messaging layers)

• Troubleshooting latency, connectivity, entitlement, and data quality issues

• Working directly with front-office users, market data teams, and infrastructure engineering

• Leading incident response and managing high-priority escalations

• Analysing usage patterns and advising clients on capacity, performance, and architecture

• Collaborating with product and engineering teams to refine features and roadmap

• Mentoring junior specialists and shaping support standards across the team

What You Bring

• Strong experience in market data support within investment banking, trading, or a market data vendor

• Deep understanding of real-time data technologies

• Solid Windows and Linux skills and comfort with scripting (Python, Shell, Perl)

• Familiarity with networking concepts, multicast, entitlements, and low-latency environments

• Ability to communicate clearly with both technical and non-technical stakeholders

• A calm, structured approach to incident management and problem solving

• Confidence operating in high-pressure, front-office-aligned environments

Why Join Us

• Work with cutting-edge market data technology used by global investment banks

• High autonomy and influence — your expertise directly shapes client success and product evolution

• A culture that values technical excellence, ownership, and continuous improvement

• Competitive compensation, strong career progression, and exposure to major financial institutions

If you’re a senior market data specialist who thrives in complex environments and wants to make a tangible impact across the investment banking community, we’d love to speak with you.
