📬 Are you the kind of CRM marketer who thrives in Customer.io (or similar ESPs), building workflows and sequences from scratch rather than maintaining what someone else set up?
🧪 Do you get a genuine kick out of running experiments, forming a hypothesis, setting up the test, reading the results, and immediately thinking about what to try next?
👀 Ready to send the world's most thoughtfully crafted marketing emails, on behalf of a company that exists to save people from inbox chaos?
If so… you might be our new Lifecycle Manager at Fyxer
Title: Senior Lifecycle Marketing & CRM Manager
Reporting to: James Lester, Growth Lead
What are we building?
An AI Email Assistant that gives professionals their time back. Fyxer organises your inbox, drafts replies in your voice, and takes meeting notes, so you can focus on the work that actually matters.
We serve everyone from individual power users to enterprise teams at companies like Knight Frank. Our users are typically in client-facing roles: sales, consulting, recruiting - where admin doesn’t just slow them down, it costs them money.
The Role:
Your focus is execution and experimentation. You’ll build and run lifecycle campaigns across email, primarily through Customer.io (and other required platforms), and run a relentless test-and-learn programme to improve how we activate, retain, and grow users, across both our prosumer and B2B audiences.
As a young, rapidly growing business, there is a lot to be learned about our Lifecycle motions, so if a fast-paced, changing environment energises you rather than frustrates you, you are extremely proactive, and you care deeply about commercial outcomes, you’ll do well here.
What you’ll do
Experiment engine: Run a continuous test-and-learn programme across lifecycle - A/B tests, segmentation experiments, send-time tests, copy variants - always with a clear hypothesis and a commercial read on results.
Campaign ownership: Build and execute lifecycle campaigns from activation and onboarding through to retention and expansion, across both our prosumer and B2B audiences.
Customer.io execution: Manage our CRM tool setup, primarily within Customer.io - workflows, sequences, segmentation, lead scoring - and keep it running reliably and scalably as we grow.
Data-driven decisions: Use data to understand where users drop off, where engagement is highest, and where the biggest commercial opportunities sit. Act on what you find.
Cross-functional work: Collaborate closely with Data, Engineering, Customer Support, Marketing, and Sales to keep lifecycle campaigns timely, relevant, and joined up across the customer journey.
Performance reporting: Report on campaign impact clearly and regularly, focused on commercial outcomes and what we’re doing differently as a result.
You might be a fit if you:
Have 4–7 years of hands-on lifecycle experience
Are genuinely proficient in Customer.io: you can build complex campaigns, workflows, and segmentation logic from scratch, not just edit what someone else set up.
Have worked in B2B - or in a D2C or consumer business with a complex, multi-stage customer lifecycle (freemium, subscription, product-led growth)
Are commercially wired - you care about pipeline, conversion, and revenue, not just open rates and send volumes
Are comfortable operating without a fully-formed playbook and can make good decisions under ambiguity
Know how to design a clean experiment, read the results, and turn them into clear next actions
Write well and take care with messaging - you understand that lifecycle is part craft
Bonus if you:
Have worked across both PLG and sales-assisted motions - ideally where those two things had to talk to each other
Know your way around tools like Clay, Apollo, or intent data platforms
Have been an early or growth-stage hire and had to build from scratch
Who will not thrive in this role
People who need full clarity before they can move - we’re still figuring out parts of this and the playbook isn’t written yet
Marketers who measure success in sends and opens rather than revenue outcomes
What We Value
We hire small numbers of exceptional people who want ownership and autonomy. You’ll be expected to work with urgency and intensity, and you’ll see your work have a direct commercial impact.
Folks that thrive at Fyxer:
You want to build from the ground up and have real impact
You want unreasonable ownership of your own world
You work hard, with intensity every day, and move incredibly quickly
You always challenge the systems you’re in to be better
Our culture is intentional. It stems from the fact we’re in the race of our lives to reshape one of the largest AI opportunities that exists: email. There is only first or last.
This requires focus and discipline. So we’ll do everything we can to remove distraction, support your wellbeing, and reward your impact.
