Design, build, and scale custom cybersecurity applications, APIs, and data-driven tools.

Engineer analytics pipelines and machine learning services in cloud environments (Azure preferred).

Guide architectural decisions to ensure performance, scalability, and maintainability.

Provide hands-on support for critical system triage and rapid response development.

🗃 Data & Analytics Engineering

Build and automate data pipelines, delta tables, and reusable datasets to support a wide range of security use cases.

Lead data infrastructure initiatives and set best practices for analytics engineering.

🔬 R&D & Innovation

Drive the prototyping and development of novel AI/ML capabilities for threat detection, anomaly analysis, and security automation.

Explore cutting-edge tools and methodologies to maintain a defensive advantage against evolving threats.

🛠 Rapid Response & Collaboration

Work closely with security operations, data science, and engineering teams to address urgent threats or vulnerabilities.

Act as a technical leader across cross-functional delivery squads.

✅ What We're Looking For

Strong background in software engineering, ideally full stack with focus on cybersecurity tooling.

Experience with cloud-native architectures (Azure, AWS, or GCP) and building scalable applications.

Familiarity with cybersecurity disciplines such as network/cloud security, cryptography, malware analysis, intrusion detection, threat intel, or red/blue teaming.

Proficiency in Python and the data science ecosystem (e.g. Pandas, NumPy, Jupyter, etc).

Experience with Databricks, Synapse, or similar analytics platforms.

Strong data engineering skills including RDBMS (PostgreSQL, MySQL) and NoSQL (Cassandra, Elasticsearch, etc).

Demonstrated leadership in setting engineering standards and mentoring junior engineers.

Excellent communication skills, capable of translating complex technical ideas into actionable insights.

🎓 Bonus Points For:

Degree in Computer Science, Engineering, Data Science, or related field.

Azure certifications (e.g. Developer Associate, Data Engineer, Solutions Architect).

Experience with offensive/defensive cyber tools, threat modelling, or applied machine learning in security.

💡 Why Join?

Build mission-critical software that defends against real-world cyber threats.

Work alongside world-class experts in security, analytics, and AI.

Tackle technically complex challenges at scale in a high-impact environment.
