Key skills
- Audience intelligence systems (fit modelling, enrichment, suppression)

At Adzact we are building an autonomous B2B ad engine. B2B companies now spend tens of billions on paid media every year. Yet most of that money still flows through tools built for B2C ecommerce or recruitment. Targeting is blunt, spend concentrates on the wrong accounts, and optimisation often just means buying more clicks from the same oversized companies. Adzact exists to fix that. We have built a purpose‑built B2B ad platform that:
- Identifies high‑fit companies using structural and intent signals
- Enforces precision targeting across LinkedIn, Meta and Google
- Suppresses wasted spend on non‑buyers and existing customers
- Surfaces person‑level engagement and buying intensity
- Automatically orchestrates campaigns, landing pages and reporting
Our clients include enterprise B2B brands across software, financial services, healthcare and security. In the last year we have grown revenue >10x and are now building the multi‑year IP that turns Adzact into a fully autonomous ad engine.
What you will do
You will join an elite, high‑output engineering team building the core of the Adzact platform. You will work across:
- Audience intelligence systems (fit modelling, enrichment, suppression)
- Person‑level intent and intensity scoring
- Campaign orchestration across LinkedIn, Meta and Google APIs
- Lead ingestion, attribution and CRM integrations (Marketo, HubSpot, Salesforce)
- Internal tooling that powers sales and customer success (Audience Audit, activation workflows)
You will help design systems that:
- Abstract away platform complexity
- Enforce guardrails to prevent wasted spend
- Balance automation with transparency
- Scale across multiple business managers and ad accounts
- Are robust against abuse, cost spikes and data inconsistency
Your work will directly influence revenue and client performance.
Tech stack
We are AI‑native and pragmatic. We use tools that move us forward. Core stack includes:
- Claude
- Code
- Databricks
- Python
- FastAPI / Flask
- Pandas and data processing libraries
- SQL (MySQL/Postgres)
- AWS
- Docker
- Platform APIs (LinkedIn, Meta, Google Ads)
We are leveraging:
- Agentic development workflows
- LLM‑assisted prototyping
- Automated test and validation pipelines
- Lightweight internal tooling rather than heavyweight enterprise frameworks
You do not need to match this list perfectly. We care about your ability to think clearly, design systems, and ship.
Who We Are Looking For
We want someone who:
- Has multiple years delivering software to external users (i.e. not just internal tools)
- Has strong Python and backend fundamentals
- Has worked with APIs and real‑world data pipelines
- Is comfortable owning a problem end‑to‑end
- Understands the trade‑offs between speed and robustness
- Can think commercially, not just technically
- Is excited by AI‑native engineering workflows
- Prefers small, senior teams over large, slow organisations
Bonus (but not required)
- Experience with ad tech, marketing platforms or CRM systems
- Experience building scoring or modelling systems
- Experience working in early‑stage or high‑growth startups
- Experience with multi‑tenant SaaS architecture
Benefits
- Training and personal development: £1000 annual learning budget plus dedicated time for skill development
- Internal build days and experimental sprints
- Family and flexibility: Flexible working to accommodate childcare and life commitments
- Full time in our Central Bath Office
- Health and wellbeing: 25 days holiday plus bank holidays, increasing with tenure
- Private health and dental cover
- Company pension (6% employer contribution)
We will be part of a friendly, ambitious team building something meaningful. We move fast, but we look after each other.
