We are looking for a Fullstack Developer to join our team and work on two technology products focused on mobile traffic and attribution.

The first product is an install attribution system built on AWS. It processes clicks and installs in real time, identifies traffic sources, and distributes events to external systems, including trackers, MMPs, advertising platforms, and push services.
The second is a domain and traffic management platform built on top of Cloudflare Workers. It combines dynamic routing and high availability with a custom web interface for managing domains, workers, and configurations.<\/p>\n

Develop and maintain backend services using Node.js \/ TypeScript.
Build and improve the web application using React + TypeScript.
Design and develop serverless solutions using AWS Lambda and Step Functions.

Improve the internal admin platform for managing domains, workers, and configurations.
Build integrations with trackers and MMPs, including Keitaro, Binom, Affise, Tenjin, and AppsFlyer.
Integrate advertising and event APIs such as Meta CAPI and TikTok Events.
Improve system reliability through retries, idempotency, error handling, validation, alerting, and self-healing mechanisms.
Participate in code reviews, technical decision-making, and feature delivery.<\/p>\n
What we're looking for
3+ years of commercial experience with Node.js \/ TypeScript.
Hands-on experience with React + TypeScript.
Strong understanding of asynchronous programming.
Experience working with external APIs, webhooks, and queues.
Experience with AWS Lambda \/ Step Functions or similar serverless technologies.
Production experience with PostgreSQL and Redis.
Understanding of distributed systems concepts, including race conditions, retries, idempotency, and consistency.
Solid experience with Git, CI\/CD, and code review practices.<\/p>\n
Nice to have
Experience in AdTech, tracking, attribution, or mobile traffic.
Understanding of mobile attribution concepts such as postbacks, deep links, and SKAdNetwork.
Experience integrating Keitaro, Binom, Affise, Tenjin, or AppsFlyer.
Experience with high-load systems and large-scale real-time event processing.
Experience with Serverless Framework \/ Infrastructure as Code.
Experience with observability tools such as Prometheus and Grafana.<\/p>\n
