at Permutive

• Job title: Customer Engineer
• Job type: Full Time
• Experience level: Junior, Mid level
• Salary: £55,000 - £75,000 per year
• Degree requirement: Bachelor's Degree
• Tech skills: JavaScript, Python
• Location requirements: Hybrid, London, United Kingdom

About the role

• Customer Engineer managing enterprise clients' technical needs and integrating solutions for a data collaboration platform. Focused on optimizing usage and enhancing customer relationships through technical excellence.

Responsibilities

• 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.
• Build integrations, features and extensions that expand the platform — both for specific customers and the broader customer base.
• Manage a dedicated book of enterprise customers, providing proactive technical guidance.
• Proactively audit how your customers use the platform to surface opportunities.
• Partner with CSMs to identify and scope expansion opportunities.
• Serve as the final technical escalation point before Engineering.
• Support Technical Services on technically complex or custom onboardings where there is not an established approach.
• Build tools, processes, and automations that serve multiple internal teams.
• Create documentation that bridges engineering and customer-facing teams, reducing reliance on tribal knowledge and supporting scalability as the team grows.

Requirements

• We're open to two types of profiles for this role.
• You might be a recent Computer Science graduate looking for a role that combines engineering with real customer impact.
• Or you might have 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 — with a foundation in coding through a bootcamp, self-taught projects, or similar. Either way, what matters is that you can write code, you're drawn to customer problems and you want to do both. Experience in ad-tech or a related data/platform domain is a plus but not required.
• 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.
• 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.
• You're energized by end-to-end accountability.
• You're 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.

• Flexible hours let you fit work around your life, whether it's hitting the gym, meditating, or handling family needs.
• A £350 budget helps you create the perfect home office setup.
• Unlimited paid time off (with a minimum of 25 days + public holidays) ensures you get the rest you need.
• Ongoing training and development opportunities fuel your career aspirations.
• We prioritise your well-being with free access to Spill, our mental health partner.
