We're looking for a Backend Developer to take ownership of backend systems for our iOS applications — from core API logic to payment infrastructure and subscription flows. 
We process subscription payments through web funnels (webview in iOS apps), so this role requires deep focus on payment systems, subscription logic, and integrations. Direct revenue impact.

What you'll do

• Develop and maintain backend services and APIs for mobile applications (iOS)
• Own backend systems related to payments and subscriptions
• Implement and optimize payment systems (Stripe and similar) 
• Build subscription lifecycle logic — rebilling, dunning, retries, cancellations 
• Work with webhooks and event-driven payment processes 
• Build and support admin panels for subscriptions and content management 
• Integrate third-party services — analytics, payment providers, external APIs 
• Design scalable backend architecture and ensure system reliability
• Work with databases — user data, payments, subscriptions
• Collaborate with product and frontend teams

Requirements

• 5+ years of commercial backend development experience 
• Strong Node.js (TypeScript) 
• REST API development, NestJS preferred 
• Hands-on experience with payment systems (Stripe or similar) 
• Real experience with subscription logic — rebilling, lifecycle, dunning
• Webhooks and async / event-driven patterns 
• Strong experience with SQL databases (PostgreSQL)
• Experience working with Redis (caching / queues)
• Understanding of scalable backend architecture

Nice to have

• Message queues — RabbitMQ / Kafka 
• Admin panels or internal tooling 
• Analytics integrations 
• High-load systems experience 
• Docker, AWS / GCP

We're NOT looking for

• Developers with only basic CRUD/API experience 
• Candidates without hands-on payment system experience 
• Candidates without real subscription logic experience 
• Developers who can't clearly explain their backend decisions

What we offer

• Work on a real product with direct impact on revenue
• Ownership of backend and payment systems
• Remote work and flexible schedule
• Fast product iterations without unnecessary bureaucracy
• Strong product team and engineering culture

Full product lifecycle — from idea to scale.

We’re building subscription products and need a Product Manager who owns the product end-to-end — from hypothesis to revenue growth. You make decisions based on data, move fast, and are accountable for results.
 

Responsibilities

• Own the product lifecycle: idea → MVP → launch → scale
• Validate ideas and define MVP scope
• Design and improve funnels: onboarding, paywall, retention
• Plan releases and manage delivery (App Store / payments)
• Track key metrics: CR, retention, LTV
• Run A/B tests and act on results
• Work with design, engineering, QA, and marketing
• Identify and manage product risks

Requirements (must-have)

• Hands-on experience with subscription products (mobile and/or Web2App)
• Strong understanding of subscription funnels
• Daily work with product metrics (CR, retention, LTV)
• Experience running A/B tests end-to-end
• Ability to define MVP scope and prioritize
• Can write clear, actionable specs
• Ownership mindset — accountable for product results

Nice to have

• Experience with attribution tools (AppsFlyer, Adjust)
• Technical background (engineering or QA)

We’re not looking for a coordinator.

You own delivery. If it didn’t ship — that’s on you.

We’re looking for a Project Manager who drives delivery end-to-end — from kickoff to release — manages timelines, removes blockers, and ensures things actually ship.
 

Responsibilities

• Drive delivery end-to-end: kickoff → development → QA → release
• Own timelines — track risks and recover delays
• Coordinate product, engineering, QA, and ops
• Identify and remove blockers
• Own the release process
• Keep stakeholders aligned on status and priorities
• Balance speed and quality

Requirements (must-have)

• Experience in product teams (not just coordination)
• Proven ownership of delivery in product development
• Strong understanding of the full delivery cycle: dev → QA → release
• Strong timeline and priority management
• Clear communication with technical and non-technical teams
• Accountability for outcomes, not just process

Plus one:

• Experience with subscription products
  or
• Experience with mobile apps (App Store / Google Play)

Nice to have

• You’ve shipped real products
• You can explain missed deadlines and recovery actions
• You focus on delivery, not activity
• You treat blockers as your responsibility

Not a fit if you mainly:

• Run standups and update boards
• Facilitate meetings without driving outcomes
• Don’t own timelines or delivery

What we offer

We process subscription payments through web funnels (webview in iOS apps), so this role requires strong focus on payment systems, subscription logic, and integration reliability.

What you'll do

• Validate subscription lifecycle logic — rebilling, renewals, retries, cancellations
• Test integrations with payment systems (Stripe and similar)
• Verify webhook handling and event-driven payment workflows
• Design and execute test scenarios for critical business logic
• Perform regression testing before releases
• Test edge cases in payment flows
  (failed payments, duplicate charges, retries, cancellations)
• Analyze logs and debug backend behavior
• Collaborate closely with backend, frontend, and product teams
• When needed:
• Write automated tests (API / integration level))

Requirements

• 2+ years of commercial QA experience
• Experience testing backend systems and APIs
• Understanding of REST API testing
  (Postman, Swagger, or similar tools)
• Experience testing payment systems or financial workflows
• Understanding of subscription logic
  (subscriptions, renewals, retries, cancellations)
• Experience working with webhooks
• Ability to write clear test cases and bug reports
• Ability to analyze logs and identify root causes
