Senior Backend Engineer

Adapty helps mobile developers to increase revenue from subscriptions. We’re a data-driven company and try to deliver the most useful features to our customers. The cornerstone of our product is paywall A/B testing tools and subscription analytics. We also develop several SDKs to help developers integrate in-apps in days not months.

We’re a team of more than 45 committed and product-driven people who like challenging tasks. We serve more than 2.5k apps and ship new features weekly. Top investors including 500 Startups, and Surface Ventures back us.

We are looking for a senior backend developer with an opportunity to work on a complicated project, have a wide area of responsibility, and have direct contact with founders.

In this role, you will...

• Create API for mobile SDKs. This is a high-load module that processes more than 100M API requests every day and serves all requests from mobile apps, from profile creation to subscription activation.
• Prepare integrations with external providers. These providers may be App Store, Play Store, Amazon S3, AppsFlyer, Mixpanel, etc.
• Be responsible for an analytical system. It is built mostly on ClickHouse with some data housing in PostgreSQL.
• Optimize the existing codebase. It will help us improve speed and stability, by implementing async logic.
• Review and test the code - nothing new here.

You will be a great fit if you have these hard skills…

• You have 5+ years of experience as a backend engineer and 3+ years working with Python.
• You are confident in SQL (without ORM) and have experience working with PostgreSQL.
• You know how to work with asynchronous code.
• You have first-hand experience with building distributed systems with Celery, Dramatiq, Kafka, Kinesis, etc.
• You know when to write tests and how to write them.
• You're actively participating in code review.

You will fit into our team if you have these soft skills…

• You like working in a team but are not afraid to be responsible for and reasonably protective of your choices.
• You try to understand the task from the customer’s perspective and can suggest tradeoffs when needed.

It’d be great if...

• You worked with ClickHouse, FastAPI, Kubernetes, and mobile subscriptions.

What you may expect from working with us...

• A flat structure without strict hierarchy.
• No bureaucracy and simple and clear processes.
• Remote work with a flexible schedule.
• Opportunity for professional growth and trying new things out.
