Payment Strategist

Voy is a healthcare platform led by clinicians. We support people managing long-term health conditions with treatment plans backed by real evidence.

Founded in 2018, we started as MANUAL, focusing on hair loss, weight loss and men’s health. As we grew, we realised we could help more people. In 2025, we became Voy and expanded into more areas of health, including female hair loss, testosterone, menopause, dermatology and diagnostics with Do Health.

Today, Voy has around 750,000 active customers and has treated more than 2 million people since we began. We work across the UK, Germany, Brazil and India to make a new future of healthcare a reality. We’re approaching $1bn in ARR and have grown more than 100% year on year, every year since inception. At Voy, we let the evidence do the talking. In a published study of over 100,000 people, those who reached 12 months in the Voy programme and stayed engaged lost up to 24% of their body weight.

Our vision is simple: to make 100 years of healthy living within reach for everybody. Our mission is to bring quality care to everyone, at scale.

We are looking to hire a mid-senior payment strategist to own how our Brazilian payments operation performs, from our acquirer and provider relationships through to fraud, chargebacks and commercial terms. You will have full ownership of the Brazil market with the independence to set direction rather than execute a plan handed to you, and will report to the Head of Global Payments, in close partnership with the Director of Patient Experience.

This is an ideal role for someone who wants to challenge themselves in a fast-paced environment and manage provider relationships, risk strategy, dispute recovery, refunds and payment performance in our most complex market in order to protect revenue we are currently losing and reduce the cost of every transaction we take. If you like problem-solving and implementing transformative solutions, this role is for you!

What you’ll be doing

Owning day-to-day relationships with our acquirers, payment service providers and local partners, including the follow-up that only works from inside the market
Supporting and in time leading commercial conversations on provider pricing and terms
Designing and running experiments across providers, including authorisation performance and fallback configurations, so that routing decisions are proven rather than asserted
Carrying our merchant category reclassification through the local approval process with our acquirers, and quantifying what it is worth
Owning fraud and risk strategy for the market: the rule set in our provider’s risk engine, the balance between blocking and reviewing, identity and verification checks, and the response when we are attacked
Running chargebacks and disputes end to end, from notification and evidence through representment to net loss, and lifting our recovery rate
Separating commercial disputes from genuine fraud and treating them differently, including owning refund reporting and the parts of it that need building first
Monitoring authorisation, conversion and chargeback performance for the market, and telling us where our payments reporting needs to go further
Setting direction and delivering through existing teams rather than doing all the execution yourself

What we need from you

A graduate degree in engineering or a similar discipline
Five to ten years in payments, gained at a bank, acquirer, provider or e-commerce business, including hands-on ownership of payments risk or payments performance in the Brazilian market
The structured way of working that comes from a product management, project management or consulting background
Hands-on depth in a risk rule engine, including rules you have retired as well as rules you have written
Command of chargeback and dispute mechanics: reason codes, representment, how pre-dispute and rapid resolution programmes settle, and scheme monitoring thresholds
Working knowledge of provider and acquirer commercials: pricing structures, interchange, merchant category classification and the local approval process
Familiarity with the local landscape: instant and recurring instant payments, installments, and issuer behaviour including unvalidated CVV
Strong data proficiency, and a willingness to be hands-on with data: you interrogate transaction data yourself rather than waiting for an analyst
Commercial arithmetic: you can price a false positive as readily as a chargeback, and build a business case that survives scrutiny
The independence to work without a local payments team above you, with the person accountable for group numbers based in London
Fluent Portuguese and professional English
Nice to have: subscription or recurring billing experience where authorisation and capture are separated by a clinical step, provider migration or orchestration experience, identity verification or device intelligence deployments, and a regulated industry background
