Technical jobs in United Kingdom

We build marketing strategies that move the numbers and we’re investing heavily in how we use data to do that.

We’re now looking for a Digital Analytics & Tracking Lead – someone who’s just as happy inside GTM and GA4 as they are in a client meeting, turning data into decisions.

If you love clean event schemas and messy whiteboards, can debug a broken data layer and then explain what it means for the business, this might be your thing.

This role is hands‑on, increasingly client‑facing, and crucial to our ongoing success.

• Audit and fix tracking across client accounts (GA4, GTM, ad platforms) – identify gaps, resolve issues, implement best‑practice setups
• Architect data layers and event structures that scale and don’t break when sites change
• Lead technical projects: server‑side tracking, consent mode v2, privacy‑compliant measurement
• Work with developers to spec and implement tracking that requires backend/API work

• Create agency‑wide standards for GA4 and GTM implementation, plus QA processes that stick
• Build documentation, playbooks and self‑serve resources so teams can work independently
• Configure Funnel.io and set up monitoring/alerts for tracking failures and data quality
• Train channel specialists on tracking best practices and proper measurement

• Analyse marketing performance across channels and customer journeys, surfacing clear "so what / now what" insight that form decisions
• Build dashboards (Looker Studio, Power BI, Funnel.io) that inform strategy, not just report numbers
• Design & run test‑and‑learn programmes (A/B tests, incrementality studies, creative and audience experiments)
• Define measurement plans and KPIs for campaigns and always‑on activity

• Present findings and recommendations to senior client stakeholders with clarity and confidence
• Be the analytics voice on key client calls and new business pitches
• Educate clients on measurement strategies and manage expectations around attribution and privacy changes
• Help shape our analytics offering into something clients understand, value, and want to buy

• You’re technical enough to fix a broken data layer, but strategic enough to explain why it matters to a client.
• You probably started your career heads‑down in GTM and GA4, but you’ve realised you enjoy the "so what?" conversations just as much as the implementation work.
• You think in events and parameters, but you can translate that into business impact without the jargon.
• You’re comfortable on client calls and can hold your own presenting to senior stakeholders.
• You get annoyed when tracking is configured badly, and equally annoyed when good data doesn’t lead to good decisions.
• You can work independently, prioritise ruthlessly, and you’re commercially aware enough to know which problems matter.

• 5‑7 years in digital/marketing analytics (agency or brand‑side), with hands‑on experience in both tracking implementation and strategic analysis
• Deep technical expertise: GA4, Google Tag Manager (data layers, triggers, variables), ad platform pixels and conversions (Meta, Google Ads, LinkedIn, TikTok)
• Strong SQL and/or BigQuery skills for deeper analysis and joining multiple data sources
• Proven track record of both auditing/fixing broken tracking AND providing strategic recommendations based on data
• Client‑facing communication skills – you can present technical concepts to non‑technical stakeholders clearly and confidently
• Experience establishing tracking standards, QA processes, and working with developers to implement technical requirements

• Agency experience managing analytics across multiple client accounts simultaneously
• Server‑side tracking (GTM Server‑Side, Segment, Snowplow), consent management platforms (OneTrust, Cookiebot)
• Experience with Funnel.io, dbt, Looker, Power BI, Tableau or similar data tools
• E‑commerce or app tracking expertise (Firebase, enhanced e‑commerce)
• Previous experience building analytics capability in an organisation (not just maintaining it)

• An additional day of holiday for each year of service, up to a total of 5 extra days.
• The option to buy an extra week’s holiday per year.
• 0.5‑day life balance day each month to do whatever you want (excludes December)
• Early finish on a Friday.
• Private health insurance which covers pre‑existing conditions, cancer care and gives cashback for routine optical and dental treatments.
• Life assurance.
• Enhanced maternity and paternity pay.
• A £1,000 payment for referring a new hire.

• Hybrid working and flexibility.
• Access to a personal trainer/nutritionist.
• Free fruit and breakfast in the Manchester office.
• Mental health support and access to professional therapists through ‘Spill’.
• Peer feedback and performance reviews tailored personal development plans and objectives.
• Access to industry‑accredited professional qualifications through our IPA membership.
• Employee voice, we consult our people on matters affecting them and encourage participation in agency surveys, our suggestions box and employee awards.
• A social buddy upon joining who helps you settle into the agency.
• Monthly agency socials and events put on by our culture committee.
• Lunch & Learn events to gain more understanding of different facets of agency life.
• All supported by a culture driven by great work, team collaboration, passion, honesty, and mutual respect for everyone.

We had always thought our business was open and inclusive. Afterall, one of our values is “Everyone matters.” We hammer home the behaviour of treating everyone with respect, seeing things from the other person’s perspective, understanding that everyone has different values, responsibilities, concerns and families.

But when you delve a little deeper into Diversity, Equity and Inclusion, this value is a great place to start but it involves so much more.

Here at TrunkBBI, we naturally welcome difference. It’s what gives us strength as a business, the wide breadth of experience, capabilities, and perspectives. And any creative business knows that the best ideas don’t come from just one place. Diversity is important, but we feel what makes the real difference is inclusivity, or the act of helping people feel valued and enabled regardless of their differences.

We have really then only just begun our diversity and inclusivity journey. We started by ensuring everyone has mandatory training to help people understand what it means to be inclusive. We’ve set up a panel of people within the business to champion difference and we have ambassadors who are gaining their IPA D, E & I certifications. We continue to learn and evolve, and realise that this is not a quick win, or a ‘one and done.’

We are adapting our practices, offering home working, flexibility around start times, offer monthly life‑balance days, access to mental health professionals, and assessing our working spaces to accommodate brilliant neurodivergent minds. And will continue to evolve to enable the differences around us.

TrunkBBI is The Creative & Performance marketing agency. Unique in our approach and our desire to do things differently, we build client teams that combine the best of abilities across creative disciplines and performance channels, our belief in our approach ensures we produce brilliant results for our clients.
