About The Team:

We are the “ThreatLabs Platform” - a small team of backend engineers. We are right at the core of the Gen – we support malware analysts, security researchers, and other experts to help them drive the efficacy of our antivirus products (Avast, AVG, Avira, Norton). Our systems ingest millions of malware samples per day and keep large amounts of data about them. We maintain APIs and datasets that are used by other teams in their work. Many of our systems are critical – everything we do has a direct impact on our customers. That is why maintainability and reliability are important to us.

We rely heavily on templating, source-control tools, automated tests, CI/CD pipelines, infrastructure as code, and anything else that will make our job easier. DX (Developer eXperience) is always on our mind, and we try to not only help ourselves but spread the knowledge across the whole company (for example, our team founded the company-

wide Python Guild, where we share what we learned). We develop and maintain libraries that make life easier for developers across the organization.

DevOps is our way ― there is nobody else to maintain our services for us. We own everything we create. We know everything about our applications thanks to extensive monitoring and logging. Automated alerts help us resolve incidents quickly during on-call duty and prevent the same problems from arising in the future. We hold ourselves to high standards in our work ― we like clean, documented, tested code.

About The Role:

As a backend engineer, you will be designing, developing, and maintaining services that ingest and store malware samples and metadata. You will also develop and maintain internal libraries and frameworks used by other teams in the organization.

Python will be your main language (we use type checking heavily, and most of our code is async), you will deploy services to Google Cloud Platform (Kubernetes) and work with cloud-based databases (CloudSQL/PostgreSQL) and datasets (BigQuery).

You will participate in code reviews. You will mentor and coach your colleagues and spread your expertise throughout the organization.

You will be part of an on-call rotation (when you are ready).

What You Will Need to Be Successful in This Role:

• Broad knowledge and experience with backend systems (preferably in Python).

• Strong experience with Python 3 (or similar language).

• Strong understanding of best practices in software architecture, clean code, and scalable solutions.

• Experience with relational databases (PostgreSQL).

• Experience with Git, CI/CD, and Docker.

• Experience with cloud platforms.

• Fluent communication (spoken and written) in the English language.

What We Can Offer:

• Annual bonus scheme.

• Unlimited PTO (paid time off), flexible working hours & home office.

• The chance to join a major global tech company listed on the S&P 500.

• Opportunity to learn and work with the best in the Digital Security industry.

• Cafeteria points are provided by Benefit Plus (meal plan, pension insurance, travel, free time activities, multisport card, and much more).

• Tuition reimbursement for job-related courses.

• Learning & Development plan.

• Sustainable home improvement bonus.

• Mac/Windows laptop and mobile phone.
