Senior Customer Success Engineer in London

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US. As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations. Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow. Role overview Synthesia is used by over 90% of the Fortune 100, and the largest deployments now run thousands of creators across dozens of markets, languages, and compliance regimes. What decides whether those accounts expand or stall is not another avatar, it is whether admins, legal, and programme owners can actually stay in control. You'll own that layer end to end: workspace setup and governance, the content lifecycle, and the analytics and integrations that close the loop. This is the work that turns a proof of concept into a seven-figure renewal, and right now it is wide open. Why this role now AI video has crossed from experiment to standard tooling inside the world's biggest companies. The next phase of growth is won or lost on whether we can make that scale safe and manageable. That is your remit. What you'll be doing Owning the end-to-end roadmap for content lifecycle, governance, and the operational layer that keeps enterprise deployments running - from workspace setup through compliance controls Getting close to enterprise customers: understanding how IT admins, legal teams, programme managers and content owners think about governance, and what "in control" actually looks like at scale Translating th

Our Purpose Mastercard powers economies and empowers people in 200+ countries and territories worldwide. Together with our customers, we’re helping build a sustainable economy where everyone can prosper. We support a wide range of digital payments choices, making transactions secure, simple, smart and accessible. Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realize their greatest potential. Title and Summary Vice President, Finance Business Partner, Payment Networks The Vice President, Finance Business Partner -- Payment Networks at Mastercard will be a senior finance leader and strategic business partner in the Payment Networks Organization, providing leadership across business strategy, growth priorities, financiak planning, performance management, investment prioritization, and decision support. This VP will lead a finance team within Payment Networks responsible for real time payments (RTP) – across international markets and RTP global products and engineering -- requiring effective business partnering and translating business, product, engineering, and regulatory requirements into financial insights, actionable plans, and executive-ready recommendations. This role partners closely with Business teams, Product, Engineering, regional and Corporate Finance, People & Capability and Controllership teams to ensure financial outcomes are aligned with organizational goals, governance expectations, and Mastercard’s strategy.

Altana is the network for trusted trade. Our AI-powered product network empowers governments and businesses to build a more resilient and secure global economy while keeping trade flowing. The Role: Vertical Technology Lead, Policy & National Security Altana’s mission is to power a new era of globalization organized around trusted networks. Nowhere is that mission more consequential — or more demanding — than in the policy and national security community, where the questions our customers bring us are matters of sovereignty, security, and how a nation understands the networks it depends on. These are the hardest programs we run. The technical bar is high and it keeps rising: the biggest opportunities are won, kept, and expanded on the strength of the technical work itself — sometimes on technical capability alone. As these engagements grow, so does the machinery large government partners expect from a serious partner: program management, delivery cadence, contractual rigor, accreditation. Left unmanaged, that machinery swamps the very people whose job is to architect and build. We’re changing how we deliver so it doesn’t. Large and strategic accounts are staffed with dedicated Implementation Delivery Managers (IDMs) who carry the program, project, and delivery-management load — and, as an account grows more complex, we trade up the team to meet it. That frees the technical leadership of the vertical to do what only it can do: hold the architecture bar, win the technical argument, and drive the last mile of product where the mission needs something that doesn’t exist yet. As Vertical Technology Lead for Policy & National Security, you own the technical outcomes for the vertical end-to-end. You are the senior technical counterpart to the vertical’s commercial leadership — setting the technical approach that wins business, owning the solution architecture and delivery that turns wins into mission outcomes, and leading the team that does the work. This is a UK-b

You'll define design direction for large, ambiguous problem spaces, anticipate risks before they become blockers, and reframe problems in ways that unlock better outcomes for customers, product teams, and the business. We're building a video platform for everyone - not a specialist tool - and we see a future where Synthesia sits alongside word processors, presentation software, and spreadsheets as a daily staple. Getting there requires design leadership that goes beyond execution: someone who helps the company make the right bets, raises the craft bar across the whole team, and builds the conditions for great design to thrive at scale.

Founded by former executives from Google, Coinbase, Flipkart, and Okta, our team includes engineers from premier tech companies and graduates of Stanford, MIT, UC Berkeley, CMU, and IITs. We are backed by industry leading investors including Accel, Naspers/Prosus, Section32, and angels like Sheryl Sandberg and Dustin Moskovitz. Headquartered in Silicon Valley and with offices in London, Bangalore and Vancouver, Ema is at the frontier of what Agentic AI can do in production — we ship real systems that run real business processes at scale. The Role You'll be an engineer who builds AI agents in production, sitting close to the customers who depend on them. This is a full-stack engineering job with an unusually short distance between your code and someone's actual workday. You'll write Go and Python, design schemas, build evals, and present your solution to a senior executive at an enterprise - often in the same week. What You'll Do Design and ship production agents. You'll build agents that are mission-critical from day one: embedded in Teams, Slack, intranets, voice lines, and email, taking real actions against SAP, ServiceNow, Workday, and a long tail of systems nobody has heard of. These run at enterprise volume under enterprise scrutiny. Own the full lifecycle. Discovery, build, eval, launch, and the unglamorous months afterward where an agent goes from good to genuinely reliable. Work directly with the people whose problem it is. You'll sit with leaders at global enterprises, extract the process from their heads, and decide what should be an agent, what should be a workflow, and what should stay human. Push your work back into the platform. The best patterns you find in the field become part of Ema's core product
