About Benchmark Mineral Intelligence

Benchmark Mineral Intelligence is the leading data and intelligence provider for the critical minerals, battery supply chain and energy transition industries. From lithium and cobalt to gigafactories and BESS, we give the world's most important companies and institutions the data and analysis they need to make strategic decisions.

We're a 150-person company at an exciting stage — Marketing is scaling from campaigns into a growth engine — building smarter systems, automation and personalised journeys that turn our market expertise into commercial impact.

The Role

We're hiring a Marketing Content Engineer to own our email marketing channel and the technical infrastructure that supports it. This isn’t a traditional email marketing role. You’ll own the channel end-to-end while building the systems, automation and AI-enabled workflows that help us scale smarter.

You'll report into the Head of Marketing and work within a lean, fast-moving team. You'll be the team's go-to for all things HubSpot, email performance, A/B testing analytics, and the data hygiene layer that underpins how our marketing database is built, tagged, categorised and maintained.

What You'll Do

Email Strategy & Campaign Execution

• Own the email marketing calendar – working with Head of Marketing to deliver email campaigns that align with broader content strategy. End to end self-sufficiency - build, deployment and reporting.
• Partner with sales on lifecycle journeys and campaigns that support commercial priorities.
• Build and optimise lifecycle nurture flows for MQL development to pull contacts through the funnel. Includes multi-step sequences for prospects based on interest and behaviour.
• Experiment with AI workflows to scale content personalisation, repurposing and campaign production
• Ensure continuity between email journeys and conversion experiences.
• Partner with sales as a marketer that is accountable for pipeline and revenue results, not just top of funnel metrics and engagement data.

HubSpot & Marketing Automation

• Own HubSpot email and lifecycle infrastructure— workflows, sequences, templates, smart content and reporting
• Develop and govern content taxonomy and tagging frameworks — ensuring content is structured for personalisation, segmentation, and reuse across channels
• Stay current on HubSpot capabilities and proactively identify ways to use new features or automation to improve efficiency and output

CRM Data Hygiene & Segmentation

• Build and maintain a robust segmentation framework across our contact database, ensuring sends are relevant, targeted, and respect contact preferences
• Use behavioural signals, intent data and engagement patterns to design smarter customer journeys and avoid overcontacting

Performance & Reporting

• Own email channel metrics — open rates, click rates, conversion rates, MQLs generated, pipeline influenced, and revenue attributed
• Own insight and recommendations from email performance — identifying opportunities to improve engagement, conversion and revenue impact
• Run structured A/B tests on subject lines, send times, content format, and CTAs — with a disciplined approach to learning and iteration
• Maintain deliverability health across our sending domains, monitoring bounce rates, spam complaints and sender reputation

About You

• ~3 years of B2B email marketing experience, ideally in a subscription, SaaS, data or media environment
• Hands-on HubSpot proficiency — you've built workflows, managed lists, set up sequences, created templates, and pulled reports yourself
• A content engineering mindset — you think about content as structured, reusable infrastructure, not just individual assets
• Tech-minded — comfortable exploring new tools, using AI to improve efficiency, and thinking systematically about how content is created and delivered
• A data-first approach — you care about CRM data quality and take ownership of keeping it accurate and useful
• Commercially aware — you understand the connection between email activity and pipeline, and you report against it
• Collaborative and organised — you work well with sales, content and ops teams, and manage a busy calendar without dropping balls
• Naturally curious about AI — you’re already experimenting with tools to make marketing faster and smarter

Nice to Have

• Experience with ZoomInfo, LinkedIn Sales Navigator, or similar tools for data enrichment
• Exposure to AEO or SEO content structuring — understanding how content organisation supports discoverability
