Overview
The Mission At Adzact, we are building an autonomous B2B ad engine. B2B companies spend tens of billions on paid media annually, yet they are forced to use tools built for B2C ecommerce or recruitment. Targeting is blunt, spend is wasted on the wrong accounts, and optimization is often surface-level. Adzact exists to fix that.
Our purpose-built platform:
- 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 brands across software, finance, healthcare, and security. In the last year, we have grown revenue >10x. We are now looking for a Senior Engineer to help build the multi-year IP that turns Adzact into a fully autonomous engine.
What You Will Do
You will join an elite, high-output team building the core of the Adzact platform. You will work across:
- Headless LLM-based UI (at the interface of AI and software engineering).
- Audience intelligence systems (fit modelling, enrichment, suppression).
- Person-level intent and intensity scoring.
- Campaign orchestration via LinkedIn, Meta, and Google APIs.
- Lead ingestion and CRM integrations (Marketo, HubSpot, Salesforce).
- Internal tooling that powers sales and customer success.
You will design systems that abstract away platform complexity, enforce guardrails against wasted spend, and remain robust against data inconsistency.
Tech Stack
We are AI-native and pragmatic. We use tools that move us forward:
- Core Stack: Python (FastAPI/Flask), Databricks, SQL, AWS, Docker.
- Workflow: Claude Code, Agentic development, and LLM-assisted prototyping.
- Integrations: Major Ad Platform APIs and CRM systems.
We care more about your ability to think clearly and ship than a perfect match for this list.
Who We Are Looking For
- 5+ years of experience delivering software to external users.
- Strong Python and backend fundamentals with experience in data pipelines.
- Ownership mindset: You are comfortable owning a problem end-to-end.
- Commercial thinker: You understand how code impacts revenue.
- AI-native: You are excited by modern, high-velocity engineering workflows.
- Seniority: You prefer small, elite teams over large, slow organizations.
Our Culture
- Communication: We are clear, direct, and transparent.
- Ownership: We take responsibility for outcomes, not just tasks.
- Learning Velocity: We absorb new tools and ideas quickly.
- Shipping: We prefer working software over perfect abstractions.
Benefits
- Learning: £1,000 annual budget plus dedicated time for experimental sprints.
- Flexibility: Support for childcare and life commitments.
- Office: Full-time in our Central Bath Office.
- Wellbeing: 25 days holiday (plus banks), private health/dental, and 6% employer pension.
Application Process
- Stage 1: 30-minute conversation with the hiring lead.
- Stage 2: Short technical interview (realistic, not academic).
- Stage 3: Face to face interview.
If you want to help build the future of B2B advertising, we would love to hear from you.
