Trade on our proprietary DSP and the industry’s leading platforms – and choose the right one for every brief. Own your portfolio, activating campaigns across the full programmatic ecosystem: display, video, native, audio, DOOH and CTV. Lead our most complex builds, and help shape the Crimtan DSP with our Product team. All from our Brighton office, as part of a global trading team.

About Crimtan
Crimtan makes the complex world of programmatic advertising simple. Since 2009, we’ve helped well-known brands reach the right people with relevant, privacy-compliant campaigns across the whole customer lifecycle.
What sets us apart is that we own the full stack:

Architect – our own DSP and campaign platform, bringing data, channels and dynamic creative together in one place.
ActiveID – our cookieless, persistent identifier, live since 2018, for precise and privacy-safe targeting and attribution.
Reflow – our dynamic creative (DCO) engine, which turns one template into thousands of personalised ads.
Compass AI – our own AI, at the heart of our ControlOS intelligence suite, putting programmatic strategy and Crimtan know-how on tap, from planning through to activation and measurement.
Personas and AI audiences – we build bespoke customer personas for each brand and use AI to model the audiences behind them, so campaigns reach the people most likely to act.
Exclusive data partnerships – with premium publishers and data providers, including Mastercard.

With teams across Europe, the Americas, the Middle East and Asia-Pacific, our vision is simple: to transform programmatic advertising into meaningful individual experiences.

The role
We’re looking for an experienced Senior Programmatic Executive to join our Trading team in Brighton, on a hybrid basis with 3 days per week in the office. You’ll own a substantial portfolio of campaigns end to end, take on our more complex and non-standard builds, and be a go-to expert for junior traders.

You’ll trade on Crimtan’s proprietary DSP alongside the leading external platforms we have access to, including DV360, The Trade Desk, Amazon DSP and Yahoo DSP. You’ll choose the right platform for each brief, and activate campaigns across the full ecosystem: display, video, native, audio, DOOH and CTV.

You’ll typically manage 25+ live campaigns, mixing tactical and strategic activity. This role is for someone who explains why performance changed, not just what changed. You’ll balance delivery, performance and cost of media, run tests, feed insight into client reviews, and help shape our DSP.

Own complex builds – lead lifecycle and sequential builds, macros and dynamic tracking across our DSP and external DSPs.
Run non-standard formats – activate audio, DOOH, CTV and rich media, using ActiveID and Reflow where they fit.
Optimise for performance and margin – balance delivery and KPIs against cost of media, and record what you changed, why, and the result.
Choose the right bidding – compare algorithmic, AI-driven and manual bidding, pick the best approach per campaign, and report the results.
Turn data into insight – write regular optimisation notes on priority accounts and contribute analysis to client reviews such as QBRs.
Test and learn – run tests such as A/B splits to prove what works.
Own tracking – independently set up pixels, conversion events and attribution windows; traffic CM360 and verification tags; and resolve standard tag issues using developer tools.
Solve problems – independently fix technical issues on your campaigns, raise clear support tickets, and escalate to your Trading Lead when needed.
Work with supply partners – activate and troubleshoot PMP and programmatic guaranteed deals directly.
Keep stakeholders aligned – proactively share optimisations and their impact with Account Management and Client Services.
Support the team – be the first line of support for junior traders, review their work, and share know-how.
Shape the product – raise console and workflow improvements with Product, with a clear problem and expected impact, and give structured feedback on new features.

You’re an ambitious trader who loves the technical side of programmatic and wants to keep growing. We’re looking for someone who is:

A confident communicator – you lead internal meetings, shape discussions and explain complex concepts in simple terms.
An owner – you take full responsibility for your work and raise the quality bar for others.
A planner – you prioritise a busy portfolio, plan ahead and flag risks early.
Commercially minded – you understand how cost of media and performance drive results for clients and Crimtan.
An innovator – you explore new tools and techniques, including AI, and share what you learn.

Essential

2–3 years in programmatic trading, with hands-on experience across several major DSPs such as DV360, The Trade Desk, Amazon DSP or Yahoo DSP.
Proven experience with complex setups: sequential or lifecycle campaigns, macros and dynamic tracking.
Hands-on experience with pixels, conversion tracking and third-party ad server tags (e.g. CM360).
Advanced Excel or Google Sheets: building pacing and reporting sheets independently.
Strong analytical skills, with experience turning performance data into clear insight and recommendations.
Excellent written and spoken English.

Desirable

Experience trading audio, DOOH, rich media or on a proprietary DSP, ideally with a specialism in CTV, Amazon or YouTube.
Experience with dynamic creative (DCO) campaigns.
Familiarity with workflow tools such as Jira or Confluence.

Global exposure – lead campaigns for well-known brands, alongside trading teams around the world.
The latest tech – trade on our proprietary DSP alongside the industry’s leading DSPs, and grow with us as we build AI tools into every step of the programmatic buying workflow, from setup and QA to optimisation and reporting.
Influence – a direct line to our Product team, so your ideas shape the platform you trade on.
Hybrid working – 3 days per week in our Brighton office, 2 days remote.
Rewards – company bonus scheme, pension, and healthcare plan (including mental health cover).
Time off – 25 days’ holiday plus UK bank holidays and a day off for your birthday.
Great culture – a passionate, friendly and transparent team.

Ready to apply?

If you want to trade on our own tech, work with global brands and grow fast, we’d love to hear from you. Even if you don’t tick every box, apply anyway – we hire for potential and curiosity as much as experience.Crimtan is an equal opportunity employer. We welcome applicants of every background and are committed to an inclusive hiring process.
