Machine Learning Researcher Intern – Prague Full-time

Application Deadline: 2025-04-30

Location: PRG5 office

Hybrid

20 hour per week

Who You’ll Work With

We are a bunch of a former security startups collectively called Threat Detection and Response. We keep an agile, fun, passionate upstart culture within Cisco. You will work in an international environment in downtown Prague, Czech Republic, closely cooperating with teams in the US. We balance collaboration and integration with autonomy and innovation to deliver the most effective solution to our customers’ problems. The unique mix of our disruptive approach to security and Cisco’s industry dominance surpasses what any other security startup could ever achieve on its own.

Who You Are

We are seeking a motivated Machine Learning Researcher Intern to join our team. The ideal candidate will have a solid foundation in machine learning concepts and a passion for applying their skills to real-world problems. This internship offers a unique opportunity to gain hands-on experience, contribute to exciting projects, and work alongside experienced researchers and engineers.

Possible Projects you could work on:

Similarity Search on Sequence of Endpoint Security Events – Each monitored device in a computer network outputs streams of cybersecurity events. This project focuses on finding common patterns in these streams to identify similarly behaving devices using similarity search techniques. The data stream is segmented into sequences of related events, which are then represented in an embedding space to identify similar sequences.

Advance Command Line Preprocessing – Building a robust system to correlate individual cybersecurity events into incidents requires understanding the activity on impacted devices rather than just matching parameters. This project focuses on understanding and normalizing command lines leading to cybersecurity events. Command lines often contain specific parameters like usernames, hashes, or random strings that obscure their functionality. Removing or masking these values can help uncover similar patterns across different devices or environments, providing robust similarity measures between cybersecurity events.

Learning on Cybersecurity Relational Data – Cybersecurity investigations often rely on relationships between entities like IP addresses, URLs, email addresses, documents, binaries, and internet users. This project examines how to use these relationships for automated threat identification or to support human analysts, like how police use notice boards with photos and wires. The primary focus is on expressing relationship data as massive graphs, with additional interest in incorporating tabular, language, and unstructured data.

What you’ll do:

• Assist in inventing, designing, developing, and evaluating innovative models on large-scale data.
• Support the design and implementation of scalable, efficient, automated Machine Learning pipelines.
• Contribute to innovation projects from idea to implementation under guidance.
• Collaborate closely with software engineering teams and customers to understand project requirements.
• Be eager to learn about cybersecurity data analytics and related tools.
• Help communicate results through internal reports, blogs, and assist in preparing for scientific papers and conference presentations.

Minimum Requirements:

• Currently pursuing a degree in Computer Science, Data Science, Machine learning, or a related field
• Proficient in English

Preferred Requirements:

• Basic understanding or coursework in software engineering is a plus.
• Experience with coursework in one or more of the following Machine Learning fields: supervised, semi-supervised, or unsupervised learning, explainability of models, advanced statistics, graph theory, game theory.
• Strong logical reasoning and problem-solving skills.
• Enthusiasm for completing tasks and making projects successful.
• Hands on experience with scikit-learn, Pandas, PyTorch, (py)Spark will boost the start

When available, the salary range posted for this position reflects the projected hiring range for new hire, full-time salaries in U.S. and/or Canada locations, not including equity or benefits. For non-sales roles the hiring ranges reflect base salary only; employees are also eligible to receive annual bonuses. Hiring ranges for sales positions include base and incentive compensation target. Individual pay is determined by the candidate’s hiring location and additional factors, including but not limited to skillset, experience, and relevant education, certifications, or training. Applicants may not be eligible for the full salary range based on their U.S. or Canada hiring location. The recruiter can share more details about compensation for the role in your location during the hiring process.

U.S. employees have to quality medical, dental and vision insurance, a 401(k) plan with a Cisco matching contribution, short and long-term disability coverage, basic life insurance and numerous wellbeing offerings. Employees receive up to twelve paid holidays per calendar year, which includes one floating holiday, plus a day off for their birthday. Employees accrue up to 20 days of Paid Time Off (PTO) each year and have access to paid time away to deal with critical or emergency issues without tapping into their PTO. We offer additional paid time to volunteer and give back to the community. Employees are also able to purchase company stock through our Employee Stock Purchase Program.

Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components. For quota-based incentive pay, Cisco typically pays as follows:

.75% of incentive target for each 1% of revenue attainment up to 50% of quota;

1.5% of incentive target for each 1% of attainment between 50% and 75%;

1% of incentive target for each 1% of attainment between 75% and 100%; and once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.

For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.
