We're looking for an architect to own the target-state architecture of our web platform and steer six engineering teams toward it.You'll have the final say on technical direction and work directly with team leads and engineers to put it into practice — aligning people through influence and clarity rather than authority.Most of your impact is upstream: translating business strategy into a coherent technical strategy, framing problems, and reducing risk while direction is still easy to change.You'll architect for sustained growth — horizontal scalability and the cross-cutting qualities (performance, reliability, maintainability, and the rest) that determine whether a platform keeps improving or stalls as users, data, and teams grow.We build a data-intensive B2B SaaS platform on Java 21, Spring, and AWS.
 

Requirements:

• 10+ years building production software, several of them in a dedicated architecture capacity, primarily on Java / Spring or C# .Net or Python.
• Demonstrated ownership of platform-level architecture spanning multiple teams.
• Deep distributed-systems expertise — microservices, event-driven and event-sourced designs.
• A proven record of scaling systems through real growth in traffic, data volume, and contributing teams.
• Command of data, caching, and search architecture (PostgreSQL, Redis, Elasticsearch) and of cloud-native operations — Kubernetes / EKS, Infrastructure-as-Code (Terraform), and CI/CD — with the ability to design infrastructure as a reusable, governed platform.
• Strong grounding in observability practices — instrumentation, distributed tracing, and defining SLOs/SLIs for production systems.
• Advanced security expertise — secure-by-design architecture, authentication and authorization, and data protection across the stack.
• Fluency moving from deep technical discussion with engineers to strategic trade-off framing with executives.
• The self-direction to be the senior-most architectural voice, aligning teams through influence and clarity.
   

Nice to have:

• High-traffic, data-intensive web experience at scale.
• AWS certification (Solutions Architect – Professional).
• Experience introducing AI-assisted, agentic development practices across the engineering lifecycle.
• Experience driving an organization through ISO 27001 and SOC 2 compliance programs.
   

Responsibilities:

• Define and own the north-star architecture, the guiding principles, and the guardrails that keep six teams coherent without becoming a bottleneck.
• Establish lightweight architectural governance — reference architectures, Architecture Decision Records, an RFC process, and a tech radar — so decisions are deliberate, documented, and durable.
• Drive domain decomposition and service boundaries (DDD, bounded contexts), and design event-driven systems with sound consistency, idempotency, and resilience semantics.
• Set the observability strategy — metrics, logging, tracing, SLOs, and alerting standards — so teams can understand system behavior, debug quickly, and operate confidently at scale.
• Shape initiatives upstream: frame the problem, weigh build-vs-buy against total cost of ownership, and set a defensible long-term direction before engineering commits.
• Treat security as a first-class architectural concern: secure-by-design, zero-trust principles, threat modeling, and data protection across the stack.
• Set the infrastructure architecture and Infrastructure-as-Code standards (e.g. Terraform).
• Build proofs of concept to validate direction and prove out emerging technology before it becomes a commitment.
• Mentor senior engineers and raise the architectural maturity of every team.

About RNK Health

RNK Health is a fast-growing telehealth brand focused primarily on the US market.

We help customers access prescription-based treatments such as NAD+, sermorelin, tirzepatide, semaglutide, and B12. Customers complete an online health assessment and receive treatment only after approval from a licensed medical provider. Approved treatments are then shipped directly to the customer.

Our business is built around recurring treatment and subscription-based care, which means we focus not only on customer acquisition, but also on conversion, retention, customer quality, refunds, and long-term value.

RNK Health has been growing for approximately 1.5 years and today has an international team of around 40–45 people across functions including Marketing, Product, Sales, Analytics, Customer Support, and Retention.

We are now entering the next stage of growth and are strengthening key functions with experienced people who can help us build scalable systems and acquisition channels.

About the role

We are looking for an experienced Affiliate Manager to build and grow our affiliate channel.

This is not a role where you will inherit a mature affiliate program and simply maintain an existing portfolio of partners.

Our affiliate function is still at an early stage, so this is a hands-on, build-from-the-ground-up role with significant ownership.

You will be responsible for developing the affiliate channel end-to-end: identifying and recruiting partners, negotiating commercial terms, launching campaigns, building strong partner relationships, monitoring economics, optimizing performance, and helping shape the processes and infrastructure needed to scale the channel.

We are looking for someone who is proactive, commercially strong, highly data-driven, and comfortable creating a partner pipeline rather than waiting for inbound opportunities.

Existing relationships with affiliates, publishers, and networks in health, wellness, weight loss, supplements, or adjacent performance marketing verticals will be a strong advantage.

What you will own

Partner acquisition
Build a strong pipeline of affiliates, publishers, networks, and strategic partners. You will proactively identify relevant partners, initiate conversations, present RNK Health and its offers, negotiate terms, and move partnerships from first contact through launch. We expect you to actively develop the channel rather than rely primarily on inbound opportunities.

Affiliate relationships
Own relationships with partners throughout the full lifecycle. You will manage onboarding, communication, campaign launches, performance discussions, optimization, troubleshooting, and opportunities for further growth. This is an end-to-end ownership role — you will not simply source partners and hand them over to another team.

Deals and unit economics
Negotiate CPA and other performance-based partnership structures. You should be comfortable evaluating partnerships through key business metrics including: CAC / CPA, Conversion rate, AOV, Revenue, Refunds, Retention, LTV. Your goal will be to ensure that affiliate growth remains commercially sustainable and that increased volume comes from high-quality traffic.

Campaign launches
Coordinate affiliate launches across RNK Health products and offers. Make sure partners have everything required to launch successfully, including: Tracking links, UTMs, Funnels and landing pages, Offers, Creative assets, Messaging, Campaign information. You will work closely with internal teams to remove launch blockers and help partners go live efficiently.

Performance and optimization
Monitor affiliate traffic, conversions, CAC/CPA, revenue, refunds, and partner-level performance. Identify which partnerships can be scaled, where performance is under target, and what needs to change in the offer, funnel, creative, traffic mix, or commercial structure. We expect you to understand what each partner is doing and continuously look for opportunities to improve performance and increase profitable volume.

Tracking and attribution
Own affiliate tracking and reporting. Make sure links, UTMs, conversions, attribution, and partner payouts are accurate. Investigate discrepancies between internal data and partner reporting and work with Analytics or other teams to resolve tracking issues. Experience with Everflow or a similar affiliate platform is highly relevant.

Cross-functional collaboration
Work closely with Marketing, Product, Creative, and Analytics teams. For example, if a strong partner can scale but requires a different landing page, offer, creative concept, or tracking setup, you will help define the requirement and coordinate internally to move it forward.

Compliance and traffic quality
Make sure partners follow approved messaging, claims, brand guidelines, and healthcare marketing requirements. Affiliate growth cannot come at the expense of traffic quality or compliance, so you will also be responsible for maintaining appropriate partner standards as the channel scales.

Who we are looking for

• 3+ years of experience in affiliate or performance marketing
• Strong experience recruiting and managing affiliates, publishers, and networks
• Proven ability to proactively source and activate new partners
• Experience negotiating CPA and other performance-based partnerships
• Strong understanding of affiliate tracking, attribution, UTMs, and reporting
• Experience with Everflow or similar affiliate platforms
• Strong understanding of CAC/CPA, CR, AOV, refunds, retention, and LTV
• Ability to analyze partner performance and make decisions based on data
• Experience managing multiple partners and campaign launches simultaneously
• Strong commercial and negotiation skills
• Strong communication and relationship-management skills
• High level of ownership and ability to operate independently
• Comfortable building processes and a channel from an early stage rather than joining an established affiliate function
• Strong working English, both written and spoken, for partner communication and collaboration in an international environment

Strong advantages

• Existing relationships with affiliates, publishers, or networks in health, wellness, weight loss, supplements, or related performance marketing verticals
• Experience in telehealth, DTC health, supplements, weight loss, or another subscription-based health business
• Experience building or significantly scaling an affiliate program from an early stage
• Strong understanding of recurring-revenue and subscription economics

Why join RNK Health?

Build a channel, not just manage one
You will have the opportunity to shape the affiliate function from an early stage instead of inheriting a mature playbook. You will influence partner strategy, commercial models, processes, tracking, offers, and the overall way the channel operates.

Direct impact on business metrics
Affiliate is viewed as an important growth opportunity for RNK Health. Strong partnerships and successful campaigns can directly influence acquisition volume, CAC, revenue, retention, and overall business growth. You will be able to see the impact of your work from the first months in the role.

High ownership and autonomy
We are looking for someone who can bring ideas, challenge existing assumptions, identify opportunities, and turn them into action. There is a short path between a strong idea and implementation when the business case makes sense.

Close collaboration with senior leadership
You will have visibility across the business and work closely with senior stakeholders while building a strategically important acquisition channel.

Become a key person within the Growth organization
Because the affiliate function is being built at an early stage, the person who successfully develops the channel will become an important contributor within the broader Marketing and Growth organization.

Broader opportunities over time
RNK Health is part of a broader health and wellness product ecosystem.As the business grows, there may be opportunities to contribute to additional products, acquisition initiatives, or related projects over time.

Working format

This is a full-time remote role.

Working hours are 14:00–22:00 Kyiv time, with a daily team sync at 18:00 Kyiv time.

The team is international and includes colleagues from Ukraine and Latin America. English is required for effective collaboration and external partner communication.

Hiring process

The hiring process includes:

1. Initial interview with a Talent Acquisition Specialist
2. Screening with RNK Health’s internal Recruiter
3. Interview with the relevant Hiring Manager

During the later stages, we will go deeper into your affiliate experience, partner network, performance cases, economics, tracking expertise, and how you would approach building and scaling the affiliate channel at RNK Health.
