Backend Developer (Python)

Hi, I’m Mykola, Product Lead at Adapty.

Before joining Adapty, I built and scaled SaaS products and worked on growth and monetization systems for subscription apps. At Adapty, I lead the team behind Adapty Ads Intelligence – our platform for analytics, management, and automation of Apple Ads campaigns. Now, we’re looking for an experienced Backend Engineer to join our technical team and help build high-performance, scalable systems that power thousands of apps worldwide.

At Adapty, we make it easy for mobile apps to manage in-app purchases and paywalls. We power 12K+ apps, process $2B+ in subscriptions every year, and have been growing fast for the last four years. Our mission is simple: help every app unlock its full revenue potential.

We are a team of 170+ passionate, product-driven people who love solving big challenges. Backed by top investors like 500 Startups and Surface Ventures, we are building one of mobile’s fastest-growing SaaS companies and aiming for number one worldwide.

Our engineering team is the backbone of Adapty’s platform. We solve hard problems, process billions of events, and scale systems seamlessly. We follow Domain-Driven Design (DDD), clean architecture, and focus on solving challenging technical problems – not routine tasks. If you enjoy working with high-load architectures, shaping systems that others rely on, and building products developers love, you’ll feel at home here.

What you will do

• Design and develop a new high-load analytics platform for Apple Ads, powering dashboards and APIs for real-time campaign insights.

• Work with queues and asynchronous processing (Dramatiq, Kafka), applying Domain-Driven Design to model complex business logic and event flows.

• Integrate deeply with Apple APIs to fetch ad metrics, campaign data, and subscription events, processing large volumes efficiently.

• Enhance error handling, monitoring, and retries, and optimize communication with app stores through API-driven solutions.

• Use a modern tech stack: Python, FastAPI, ClickHouse, PostgreSQL, Redis, Kafka, Docker, Kubernetes, ensuring high observability and fault tolerance.

About you 

• You have 5+ years of backend engineering experience with a strong Python background
• You possess expertise designing APIs that handle high-load, mission-critical traffic
• You have solid hands-on experience with SQL/NoSQL databases
• You're familiar with FastAPI/Django and message brokers like Kafka or RabbitMQ
• You have experience integrating with third-party APIs, especially Apple APIs (a plus)
• You bring a proactive mindset: you anticipate problems, propose better solutions, and make thoughtful trade-offs
• You demonstrate strong ownership and communication skills—comfortable defending technical decisions and collaborating across teams

What's in it for you

• Strong product with industry-best metrics. Adapty is among the top 5% fastest-growing SaaS companies.
• Career growth and competitive compensation. Build your team, own critical product areas, and grow with us.
• Direct communication and ownership. No bureaucracy, no politics — just impact.
• Flexible remote work. Join us from anywhere, with a schedule that fits your life.
• Additional benefits. English lessons, sports reimbursements, laptop coverage, and more.
