ThreatMark | Security, Machine Learning | REMOTE(World) / Brno, Czech Republic | Equity

ThreatMark protects >60M end users from finacial fraud and saves > $1.2M every day in losses.

We are working with banks in EU and US to protect their end users.

We develop large-behavioral models that recognizes returning users by their mouse movements, keystroke timings and sensoric data (accelerometer, gyroscope).

We detect cyberthreats (e.g. malware, phishing, scraping) by exploiting browsers/sandboxes of devices.

We manage ~PB scale of data and provide realtime scoring in milliseconds driving authentication/authorization flow (2nd factor).

Stack: [python, typescript, rust], [redis, postgresql], [aws, terraform] ...

We are looking for exceptional engineers to build with us and be part of the success:

- Backend Engineer [rust, python] - low-latency stream processing engine, rewrite python microservices to rust, build new detection features

- DevOps Engineer (IaaC in AWS)

- AI Tech Lead (loops & graphs guru, real ML background)

- Security Researcher/Engineer

- Product Manager [USA]

- Fraud Detection Specialist

- Partner Manager

Logistic regression re-discovered incl. binary cross-entropy cost function, gradient descent, including all the math needed for that. It's assumed that you can sum and multiply two numbers.

Thank you. I believe that now the article deserves an update :)

Let's explore searching in metric spaces a indexing structure called Vantage Point Trees

ThreatMark | Software Engineer, Security, Machine Learning | Remote | Brno, Czech Republic

When someone steals your credentials, whether it is bank, crypto account or email, it is unpleasant experience. Our goal is to remove fraud and simplify authentication in online world. We develop threat detection (e.g. malware, phishing, scraping) with behaviour biometry which recognizes returning users by their mouse movements, keystroke timings and sensoric data. We manage dozens of TB of data and provide realtime scoring in milliseconds driving authentication flow (log in / 2nd factor).

Stack: python, javascript, sklearn, cassandra, kafka, redis, kafka, docker

DevOps: linux, ansible, terraform, aws, openstack, prometheus, grafana

Data: Random forests, gradient boosting, markov chains....

We are three years on market, backed by two VCs and we are going to have about 4M$ revenue this year. Even that we work with top EU banks and goverment agencies we are NOT a corporate ourselves. I still code with the team, we just have fun, solve hard problems and get stuff done !

Are you tech/security enthusiast ? Do you often live "in the flow" and loose track of time ? You know what happens, when EIP register points to address with 0xCC ? Could you implement O(n*log(n)) sort ? We are looking for bright minds to join our engineering and data science team.

We are looking for positions:

- Software engineer (python)

- DevOps engineer / Cloud operations engineer

- Product reliability engineer

- Data scientist
