Implementation Engineer

Permutive

About Us Permutive’s mission is to rebuild data in advertising to protect privacy. The open internet needs a sustainable foundation that funds the free & open online experiences we all rely on. Permutive’s data collaboration platform uses edge technology to securely process data where it is and AI to discover signals that drive performance—respecting consumers’ privacy preferences while delivering outcomes for publishers & advertisers. Our customers include some of the world’s largest media companies and advertisers—including News Corp, Warner Brothers Discovery, Hearst, The Guardian, Sky, State Street, Sonos, and Apple—and we’re backed by leading investors like SoftBank Vision Fund and Y Combinator. About the Team The Customer Engineering team sits at the intersection of our customers and our product & platform. This is a proactive technical role — if an enterprise customer has a Customer Engineer, they have a dedicated engineer who knows their account deeply, drives value from the platform and builds solutions that grow the relationship. About the Role As a Customer Engineer you'll own a book of enterprise customers end-to-end — proactively auditing how they use the platform, identifying opportunities for expansion, building integrations and extensions using established patterns and acting as the technical partner to Customer Success. You'll be the person our customers rely on for technical excellence, and the person our internal teams look to for ground-truth on how a customer is using our platform. What you’ll be doing? Core Responsibilties - Where you'll spend most of your time * Platform & integration development: Build integrations, features and extensions that expand the platform — both for specific customers and the broader customer base. You'll work with established architectural patterns and existing platform capabilities, using tools like AI-assisted development to move quickly. Examples include activation workflows, dashboard customisations and integration implementations. * Strategic account partnership: Manage a dedicated book of enterprise customers, providing proactive technical guidance. You'll maintain a regular cadence with Customer Success Managers, focusing on account health, value realisation, and commercial opportunities. You're not waiting for tickets — you're anticipating what your customers need before they ask. * Usage auditing & value optimisation: Proactively audit how your customers use the platform to surface opportunities — whether that's driving more value from underutilised capabilities (e.g. NLP/AI products) or reducing waste (e.g. unnecessary data collection). You think beyond the literal technical question to the broader business implications. * Upsell & cross-sell support: Partner with CSMs to identify and scope expansion opportunities — such as building out client-facing dashboards, scoping new product applications, or demonstrating the value of features the customer hasn't adopted yet. You bring engineering capability to commercial conversations. Contributing Responsibilities * Advanced troubleshooting & escalation (L3): Serve as the final technical escalation point before Engineering, handling complex issues that require deep account context — client organisational settings, workspace-level changes, and advanced debugging. This takes context-heavy work off Engineering's plate and gives customers faster resolution. * Complex onboarding support: Support Technical Services on technically complex or custom onboardings where there is not an established approach. Standard onboardings sit with Technical Services. * Internal tooling & automation: Build tools, processes, and automations that serve multiple internal teams — Engineering, Sales, Technical Services, and Customer Success. Examples include demo tools, reporting utilities, bulk activation scripts and competitor audits. * Documentation & knowledge building: Create documentation that bridges engineering and customer-facing teams, reducing reliance on tribal knowledge and supporting scalability as the team grows. What we're looking for? * We’re looking for someone with 2–3+ years of client-facing technical experience — in a role like Solutions Engineer, Technical Consultant, Product Engineer, Customer Engineer, Implementation Engineer, or Customer Support Engineer. * You’ve navigated commercial conversations, translated between technical and non-technical stakeholders, and you’re ready to own a book of enterprise customers end-to-end. * You have a coding foundation — from a CS degree, bootcamp, self-taught work, or similar — and you’ve shipped code that real people use, whether professionally or through substantial personal or open-source projects. You’re comfortable with JavaScript, Python, or similar, and deploying to production. * Experience in ad-tech or a related data/platform domain is a plus but not required. Technical skills * Comfortable working with APIs, data integrations, and web technologies. * You can read and write code (JavaScript, Python, or similar), debug across systems, and aren't intimidated by deploying software to production environments. * You're comfortable using AI-assisted development tools to move faster. Customer empathy * You can translate between technical and non-technical stakeholders, manage competing priorities across accounts, and maintain quality under pressure. * You think commercially as well as technically — you see the business implications of a customer's technical setup, not just the technical facts. Ownership mindset * You're energized by end-to-end accountability. * You'd rather build a repeatable solution than patch the same problem twice, and you proactively surface risks and opportunities rather than waiting for them to escalate. Communication * A clear, structured written and verbal communicator who provides clarity to customers and internal stakeholders. * Comfortable documenting your work and contributing to a shared knowledge base What we’re offering We take a structured, objective approach to salary-setting, which is based on marketing information, our compensation strategy, and your experience and capability assessed through our interview process. For a typical candidate who meets our requirements, we pay a base salary of £70,000 - £85,000. Permutive Benefits * In this together: As a full-time employee, you'll become a shareholder with stock options, sharing in our collective success. * Family Comes First: Primary caregivers receive up to 6 months of fully paid leave and secondary caregivers receive 3 months of fully paid leave to bond with their little ones. * Your Health, Our Priority: Private medical insurance through Bupa ensures you get fast access to quality care whenever you might need it. * Your Time, Your Way: Flexible hours let you fit work around your life, whether it's hitting the gym, meditating, or handling family needs. * Upgraded Workspace: A £350 budget helps you create the perfect home office setup. * Recharge & Refocus: Unlimited paid time off (with a minimum of 25 days + public holidays) ensures you get the rest you need. * Grow with Us: Ongoing training and development opportunities fuel your career aspirations. * Mental Health Matters: We prioritise your well-being with free access to Spill, our mental health partner. * Secure your future: Our pension plan with Penfold helps you secure your financial future (employer contributes 3%, employee contributes 5%). Work Your Way Permutive trusts you to manage your time and deliver results. Our hybrid model allows you to choose where you work best, whether in your own productive space or our London (Farringdon) or New York (Union Square) offices. That said, none of us work alone; we are part of a team.  To foster collaboration and connection, teams in these locations come together in person at least once a week and are encouraged to benefit from being in our offices to meet with teams more often. Commercial and customer-facing teams are encouraged to embrace in-person interactions to build lasting relationships with clients and colleagues.  Every Permutive employee gets together in person at the company’s Annual Kick Off for a week in February.  Each year’s event promises to be an exciting opportunity for us to come together, reconnect with colleagues, and align on our shared vision for the year ahead. Diversity, Equity & Inclusion At Permutive, we’re taking a thoughtful, intersectional, long-term approach to diversity, equity & inclusion. We care deeply about creating an inclusive work environment that allows everyone to flourish, and we are taking continual action to progress in that direction. We’re committed to hiring people regardless of race, religion, colour, national origin, sex (including pregnancy, childbirth, and related medical conditions), sexual orientation, gender identity, age, neurodiversity status, disability status, or otherwise.
