Junior Marketing Manager — Hybrid + Equity & Growth in London

About the role

As Junior Marketing Manager at Happl, you’ll be the all‑rounder at the heart of our marketing function – picking up a content brief in the morning, running a partner launch over lunch, and helping pull together an event in the afternoon. You’ll work across the entire marketing mix, from content and campaigns to partnerships, events, brand, and community.

This hands‑on role gives you real responsibility from day one. You won’t be siloed into a single channel or stuck on slide decks – you’ll be writing, building, organising, briefing and shipping across whatever the business needs that week. You’ll collaborate directly with the GTM Lead, Content Marketing Manager, Demand Generation Manager and the founding team, gaining a front‑row seat to how each part of an early‑stage SaaS business fits together.

If you want to dive into all aspects of B2B marketing – the strategic side, the creative side and the messy operational side – this is the role that gives you all three. The faster you learn, the more you’ll own, and the more your fingerprints will end up across the business.

What you’ll be doing

• Supporting the planning and delivery of marketing campaigns end‑to‑end – from briefing creative and writing copy through to launching, tracking and reporting back on what worked.
• Supporting the Content Marketing Manager with copy across formats – blog posts, customer stories, landing pages, social posts, sales enablement – keeping a consistent voice across everything Happl puts out.
• Helping run our partnerships programme – coordinating co‑marketing activities with benefits providers, advisors and ecosystem partners, and making sure every partner moment ships on time.
• Owning the operational side of events – supplier coordination, attendee logistics, booth set‑up, follow‑up sequences and the post‑event recap that turns activity into pipeline.
• Helping pull together our presence at industry events, founder breakfasts and dinners – from guest list curation to on‑the‑day execution.
• Building and scheduling email campaigns, newsletters and nurture sequences in our marketing automation platform – making sure every send is sharp, on‑brand and properly tracked.
• Supporting on social – ideating posts, scheduling content, engaging with our community and helping build Happl’s presence on LinkedIn in particular.
• Pulling weekly performance reports across channels using GA4, Looker Studio and our CRM – spotting trends and translating them into next steps.
• Helping keep our website fresh – updating pages, launching new ones and shipping small experiments to improve how visitors experience the brand.
• Coordinating with Sales and Customer Success to surface customer stories, feedback and proof points that can be turned into marketing material.
• Using AI tools like Claude and ChatGPT every day to accelerate copywriting, research, audience analysis and reporting – building workflows that let a small team move like a much bigger one.
• Bringing fresh ideas to the table – new content angles, new partner ideas, new event formats – and being willing to roll up your sleeves and prove them out.
• Helping keep the marketing function running smoothly – calendars, trackers, briefs and the small bits of organisation that keep a fast‑moving team aligned.

What we’re looking for

• 1‑3 years in a marketing role – ideally in a B2B SaaS, scale‑up or agency environment where you’ve had to wear multiple hats and own things end‑to‑end.
• A genuine all‑rounder – you’re happy moving between content, events, partnerships, social and operations and you don’t need to be told which lane to stay in.
• A strong writer who can shift between a thought‑leadership piece, a punchy social post and an event invite without losing the voice or the point.
• Comfortable with numbers – you can pull a report, read a funnel and explain what changed and why without hiding behind jargon.
• Hands‑on experience with at least a couple of these: HubSpot, Salesforce, GA4, Looker Studio, LinkedIn, Webflow, ClickUp, Canva or similar.
• AI‑native instinct – you already use tools like Claude and ChatGPT to do better work, faster, and you’re always looking for the next workflow to automate.
• Organised and self‑directed – you can hold a lot of moving pieces, stay on top of deadlines and ship things without being chased.
• Bias to action over polish – you’d rather get something live, learn from it and improve than wait three weeks for the perfect launch.
• A team player who takes feedback well, asks good questions and owns their mistakes – we move fast and that only works when everyone’s honest.
• Familiarity with the HR tech, fintech or employee benefits world is a bonus but not required – curiosity and the ability to get smart quickly matters more.

What to expect

You’re joining a marketing function that’s being built in real time. There’s no playbook handed to you, no rigid process to follow and no neat job description that contains everything you’ll end up doing. You’ll learn by doing – across more parts of the business than most marketers get exposed to in their first five years.

Expect to be pushed. You’ll be given more responsibility than is comfortable, and the trust to run with it. The trade‑off is the rate at which you’ll grow – the people who thrive at Happl tend to look back six months in and barely recognise the marketer they were when they started.

This is a role for someone who wants the variety, the visibility and the genuine ownership that only comes with being early. You’ll be in the room where decisions get made and you’ll see exactly how marketing connects to product, sales, customer success and the wider business. If that sounds like the kind of environment you want to learn in, you’ll get a lot out of it.

Why join Happl

• Be part of building something that genuinely matters – the future of how companies support their people.
• Competitive salary that reflects the impact you’ll have.
• Real equity – a meaningful stake in what we’re building together.
• Hybrid working from day one, with the trust and flexibility to do your best work.
• Your own Happl account – use the platform you’re helping to build and shape.
• Private health insurance, because we genuinely care about how you’re doing.
• Dental insurance, including family cover.
• A personal wellbeing budget to spend however wellbeing works for you – no questions asked.
• A dedicated L&D budget to grow in the direction that excites you.
• Pension from day one – we’re invested in your future, not just the short term.
