Copy Lead in London

Mira is a San Francisco-based hormonal health company that's helped over 350,000 women test, track, and navigate their hormones, from fertility through perimenopause and everyday wellness.

Our fluorescent hormone-testing technology is unique on the market: instead of a simple positive/negative line, it gives you a real, quantitative lab reading at home, validated against the gold-standard ultrasound and used in studies across 50+ universities and by 5,000+ healthcare professionals.

We built Mira on one principle: personalized care backed by science, not guesswork.

• About the position
• We're hiring a

Copy Lead to own messaging architecture and copy — brand, campaign, product, and claims language — across Mira.

Think scroll-stopping lines that make women fall in love with our brand.

Catchy, scannable, and compliant language about the product — clear and purchase-driving.

Your job is to build well structured and flexible messaging system for the team — copy libraries, style guides, training — that lets the rest of the team execute at that same bar, without you writing everything.

This is a new senior role on our creative team, created to give copy a dedicated owner as Mira scales.

You'll report to our Creative Director and lead two copywriters — one focused on Paid Channels, one on Lifecycle.

Requirements

• 5+ years of copywriting experience, including senior or lead-level ownership of brand or campaign messaging.
• Experience writing in a regulated or compliance-sensitive category (health, finance, wellness, or similar) is a strong plus.
• Genuine copy craft— you write hooky, scroll-stopping lines that naturally touch people. Copy is scannable, human, and clear at a glance — never generic, vague, or overloaded.
• Product marketing fluency— you naturally question the business goal behind each piece of copy, dig deep into product and persona research, and deliver the message that actually serves that goal.
• Fluent with AI-assisted writing tools, but with a STRONG judgment to know what to keep, what to rewrite, and what to throw out.
• A portfolio showing range across campaign, product, and multi-channel copy — not just one format.
• Experience training, editing, or managing other writers.
• Nice-to-have: femtech or wellness background; prior experience managing writers directly.
• Details

The role is a remote FT position with flexible working hours.

Responsibilities

• Own messaging architecture and top-level copy for every major campaign and product launch.
• Maintain strong, up-to-date brand and product copy — claims and core language — including ongoing experimentation in partnership with legal.
• Build and maintain the team's copy libraries, style guides, and training materials — setting and evolving Mira's brand voice.
• Edit, QA, and coach copywriters' and content team output to a single, consistent standard.
• Manage and grow the two copywriters — day-to-day direction, performance, and hiring as the team scales.
• Partner with the Creative Director on how copy and design work together within the broader creative system.
• Flag and resolve repeating claims and compliance questions before legal review, escalating only what's new or genuinely ambiguous.
• Join one of the fastest-growing femtech companies in the U. S., driven by a strong mission to advance women’s health and expand access to care.
• Be part of a passionate, highly motivated, and international team dedicated to making a real difference in people’s lives.
• Thrive in a fast-paced startup environment where your work directly impacts company growth, strategy, and key decisions.
• Enjoy real opportunities for career growth, with the ability to shape, build, and develop teams as we scale.
• Work in a flexible, fully remote environment that supports autonomy, ownership, and independence.
• Receive a competitive salary along with a performance-based bonus system tied to OKRs.
