Job Description

Manager, Client Success, SpringServe
London, UK

Hybrid Schedule (M/F remote, T/W/TH in-office)

At Magnite, we cultivate an environment of continuous growth and collaboration. Our work impacts what millions of people read, watch, and buy, and we’re looking for people to help us tackle that responsibility with creativity and focus. Magnite (NASDAQ: MGNI) is the world’s largest independent sell-side advertising platform. Publishers use our technology to monetize their content across all screens and formats including CTV / streaming, online video, display, and audio. Our tech fuels billions of transactions per day!

We are seeking an experienced technical account manager to join our Client Success team in London. This role sits at the intersection of technology and client relationships, where you'll be instrumental in driving our growing EMEA business.

As a technical account manager, you will be on the front lines of expanding our business across EMEA. You'll work directly with publishers, broadcasters, and streaming partners to architect custom solutions using Magnite's technology stack. This is a true generalist role that requires equal parts technical expertise, business acumen, and client relationship skills.

You'll be challenged daily with complex technical problems while building deep, consultative relationships with clients. You'll need to understand the ad tech ecosystem, identify opportunities for growth, and design technical solutions that enable their success. You will need strong analytical and troubleshooting skills to get to the root cause of technical problems that arise. This role requires someone who thrives in ambiguous situations, enjoys solving technical and quantitative problems, and gets genuine satisfaction from making clients successful.

In this role you will:

• Collaborate closely with premium EMEA clients to deeply understand their underlying business models and architect custom technical integrations using the SpringServe technology stack.

• Act as the frontline engineering mind to diagnose and resolve complex technical issues across the product suite (including SSAI issues, data centre routing, ad server logic, discrepancies, etc.).

• Perform detailed data analysis to identify systemic patterns, diagnose platform drop-offs, and optimise client yield.

• Partner actively with the local Commercial and Sales teams on strategic pitches, live platform demonstrations, and technical conversations to secure new regional business.

• Function as the vital link between the market and our technical core, translating complex client requirements and product friction into clear, actionable feedback for global Product and Engineering teams.

• Master the intricacies of video ad serving and programmatic operations, maintaining a deep understanding of evolving CTV, OTT, and premium video workflows

We’re looking for someone with:

• 6+ years of experience in solution engineering, technical troubleshooting, or technical account management roles.

• Service-oriented individual who is motivated by helping clients and teammates succeed

• Strong technical troubleshooting skills to diagnose issues in complex, technical systems

• Exceptional problem-solving skills - enjoys tackling ambiguous problems and finding creative solutions

• Data-driven decision maker, experienced in analysing performance metrics and using data to improve efficiency and yield.

• Client-facing experience and the ability to translate technical detail into actionable insights for partners and internal stakeholders.

The following experience would be a plus, but is not required:

• Desire to collaborate closely with a tight knit, all-star customer success team

• Familiarity with data querying and scripting languages (such as SQL, Python, and Pandas) and utilizing AI productivity tools (e.g., Claude Code)

• Experience with video advertising, CTV, publishers, and the ad tech ecosystem

• Experience providing technical support for clients of a SaaS platform

Comprehensive Perks and Benefits

• Holiday Breaks and Quarterly Wellness Days

• Equity and Employee Stock Purchase Plan

• Family-Focused Benefits and Parental Leave

• Private Medical Insurance

• Competitive Pension Plan
