Java/Linux On-Call Engineer

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 PLN net/month B2B (that includes regular fulltime development work + OnCall rotations which we estimate on ~10h~20h on rotation week per person on shift, 4 people = 4 weekly shifts per month)

• Private healthcare

• Multikafeteria

• Free parking

As a Java/Linux On-call Engineer, you'll:

• This is development-primary role (this role is DevOps, but more Dev than Ops)

• Developing new and refactoring existing data processing and data ingestion services

• Make sure Big Data File Ingestion pipelines are running

• Figure out dependencies of software, untangling when needed, cut when needed

• 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)

• Work with AWS Services

• Work in a small and effective team of high-performers and collaborating with 3-4 other teams around that ecosystem

• Work in PST Timezone. No core hours, but sync meetings are in PST, typically 3-4 times a week. Need to cooperate with PST zone devs from other teams. Development can be done on your own schedule. Manager of the team is in PL

• Regular work (development) is happening over ~230 days a year (polish holidays are in force and also 20 additional days without providing service)

• You'll take part in 24/7 365 on-call rotation - current pattern is that over week there is some maintenance needed and usually there is 1 day over 2 weekends a month that require more attention - around 5-8h) - if you can automate operations, fix it, delete it? to make sure weekends and On-Calls are not needed - THAT'S EVEN BETTER, WE NEED YOU

The candidate must have:

• 3+ years of strong backend development experience (ideally Java, but Scala/Kotlin/C#/PHP/C++/Rust are fine too if you are sharp and willing to switch to java)

• 3+ years experience with relational databases (MySQL, PostgreSQL, etc.)

• 2+ years of Linux experience

• Strong debugging skills

• Sharp axe

• Great communication skills in English to work effectively in an international team

• Love On-Call :]

Nice to have:

• Data Engineering/ETL/Big Data experience

• Knowledge of Linux processes, shell scripting, service management and networking

• Python, Bash expertise

• AWS Services knowledge (EKS, EMR, EC2)

• Apache Airflow, Trino, Spark knowledge
