Job description

LoopMe is the leading in-app monetization and programmatic advertising platform. We reach a mobile audience of over 900 million monthly unique users globally and process over 200 billion ad requests. The Chartboost SDK is the highest-integrated independent mobile ad SDK and through the Chartboost Exchange, Ad Network and other services, we empower mobile app developers to build businesses, while connecting advertisers to highly engaged audiences.


What we need:

We are looking for a backend engineering leader to help build our newly formed Exchange team. You'll work on a system that processes hundreds of thousands of requests per second and conducts a real-time auction to find and deliver the most effective ads from our global partners. We trust our engineers to own this critical system and handle the full life cycle of feature development, from initial design all the way to shipping into production.

Our system is written in functional Scala and has plenty of opportunities to flex your distributed, low-latency programming muscles, using technologies like mongoDB, kafka, and others.


What you’ll be doing:

  • Build and lead a team of engineers working on our exchange

  • Design, build, and evolve our backend services and frameworks for our advertising ecosystem

  • Define and own APIs and developer facing tools that improve how teams ingest, process, and use data

  • Work effectively with other engineers, system architects, QA, and Operations teams to implement enhancements and issue resolutions

  • Lead technical discussions and come up with innovative ways to improve the product and process

  • Troubleshoot issues with applications, technologies, and infrastructure

  • Mentor engineers across the team, raising the bar for code quality, testing, and software craftsmanship

  • Think creatively and work independently - collaborating with others as needed to maximize efficiency and throughput

  • Deliver quality work on time while driving developer productivity across the organization


Qualifications:

  • BS in Computer Science or related field

  • 3+ years of Scala programming experience

  • 6+ years of software engineering experience

  • A proven track record of designing and delivering large-scale software systems

  • You have a deep understanding of microservices and distributed systems with hands-on experience implementing them at scale

  • You are experienced with software development in high-capacity, high-traffic, high-availability websites/systems

  • You have experience working in an agile environment


The following experience would be a plus:

  • 2+ years of AdTech experience (DSP, SSP, Exchange)

  • Background working with or building a mobile SDK or mobile games

  • You have worked with distributed messaging services, like Kafka

  • You love talking about the intricacies of OpenRTB

  • Strong skills in data engineering 


Benefits:

  • International work environment

  • Flexible working schedule with a hybrid working model (50% of the worktime from the office)

  • Annual performance bonus (up to 8%)

  • One month of workation (work from any location worldwide for one month)

  • Multikafeteria
