Offer description

Correct Context is looking for a Java/ Linux On-Call Engineer for Comscore in Poland and around.

Comscore is a global leader in media analytics, revolutionizing insights into consumer behavior, media consumption, and digital engagement.

Comscore leads in measuring and analyzing audiences across diverse digital platforms. Thrive on using cutting-edge technology, play a vital role as a trusted partner delivering accurate data to global businesses, and collaborate with industry leaders like Facebook, Disney, and Amazon. Contribute to empowering businesses in the digital era across media, advertising, e-commerce, and technology sectors.

We are building new team of 4 people (3 already hired) to drive development and maintenance of few Comscore critical systems. Those systems are core part of infrastructure and require on-call rotations to make sure systems are running and delivering value.

We are looking for developers with DevOps mindset - This is NOT a SysAdmin role, this is development first role and operations role, not operations only. If you can debug stuff on Linux, write/develop software and are not afraid of random pieces of code, let's run.

We offer:

• Real big data projects 🚀
• An international team (US, PL, IE, CL) 🌎
• A small, independent team working environment 🧑‍💻
• Flexible work time ⏰ (but with on-call service)
• High influence on working environment
• Hands on environment
• Fully remote or in-office work in Wroclaw, Poland 🏢
• 16,000 - 22,000 PLN net/month B2B (that includes regular fulltime development work + OnCall rotations which we estimate on 10h20h on rotation week per person on shift, 4 people = 4 weekly shifts per month) 💰
• Private healthcare 🏥
• Multikafeteria 🍽️
• Free parking 🚗

If you don't have all the qualifications, but you think there is a match, let's talk!

The recruitment process for the Java/Linux Engineer position has following steps:

1. Technical survey ~ 10min
2. Technical screening - 30 min
3. Technical interview - 1h-2h (depending on your experience and how fast we can go through some things)
4. Interview with manager - ~30 min

Your responsibilities

1. This is development-primary role (this role is DevOps, but more Dev than Ops)
2. Developing new and refactoring existing data processing and data ingestion services
3. Make sure Big Data File Ingestion pipelines are running
4. Figure out dependencies of software, untangling when needed, cut when needed
5. Work with technologies like: Main - java, python. Legacy (debug/discovery): perl, c++, c generated by python and compiled on the fly. Data - aws s3 (i.e. parquet), 400 node postgresql cluster, mssql clusters, spark, apache airflow and other random tools (no MongoDB though!)
6. Work with AWS Services
