About Radiant Security

Radiant Security is a Bay Area Cyber AI Startup that raised funding from top tier investors.

Our vision is simple: enable all security teams, to perform security operations with the efficiency and effectiveness needed to prevent breaches. We’re a small team of researchers and engineers with a deep focus in cyber and AI. Our product automates the triage for any security alert leveraging deep research, big data and dozens of AI Agents.

Join us and boost your career with hands-on AI experience.

This is a hybrid position and we are attending the offices 3 times a week (Vila Olimpia, São Paulo, Brazil).

Radiant Connectors Team

The Connectors team plays a critical role in the success of our product. Without our APIs, we wouldn’t be able to ingest customer data—and without data, our AI magic doesn't happen. APIs are truly the heart of our platform.

Connectors ensure data flows smoothly from the customer’s environment into our system, enabling our AI to analyze it and determine its relevance. They help the AI understand the context and structure of the data, deciding whether or not it's useful.

We’re constantly looking for creative ways to work around customer-specific requirements and make sure integrations are clean, reliable, and well-aligned with the rest of our system architecture.

• There’s room to actively participate in product and technical decision-making
• You’ll have real autonomy to design and implement solutions

Team's philosophy: it is ok to not know something and ask for help.

Key Responsibilities

• Build business logic for all connector types (e.g. webhook, polling, syslog, etc.) and contribute to various design patterns to make this easier.
• Monitor, troubleshoot, and enhance the performance of connectors, ensuring minimal downtime and high reliability.
• Collaborate with engineering and product teams to refine technical requirements for product asks and right-sizing engineering solutions to meet them.

What we're looking for

• Experience with different sorts of integration methods like REST, Webhooks, etc.
• Solid programming skills in Python or Javascript (nodejs).
• Familiarity with cloud infrastructure (AWS, GCP, or Azure) and their respective services (e.g., S3, SQS).
• Knowledge of distributed systems and techniques for building fault-tolerant, high-availability platforms.
• Strong understanding of various database and search technologies (e.g. SQL, ElasticSearch, MongoDB).
• Proficiency in English (at least advanced level) for effective communication and collaboration within the team.

Nice to Have

• Hands-on experience in containerization and orchestration (Docker, Kubernetes) for deploying scalable data services.
• Experience in monitoring and troubleshooting data platforms, using tools like Prometheus, Grafana, or Datadog.

Why Join Us?

Beyond the challenging data and platform engineering problems and working with a high-caliber engineering team, working at Radiant is major opportunity to impact security teams by reducing their workload and mitigating security incidents quickly. Come help shape a future where people can sleep more easily due to a smaller blast radius of cyber threats.
