AI Software Engineer

### Role Overview Blaze is looking for an AI Software Engineer focused on Offensive Cybersecurity Tools and Capabilities to help us build the next generation of offensive security tools and AI-powered capabilities for cybersecurity usage. This role is for someone who wants to work where applied AI meets real-world adversarial thinking. You will design and ship production-grade systems that support areas such as agentic pentesting and red teaming, as well as AI-powered code review for novel vulnerability discovery. You will work closely with experienced security practitioners to turn offensive security knowledge into software that creates real leverage. This is not a research-only role, nor is it a generic AI engineering job. ### Key responsibilities - AI-powered security tooling: Design and build AI-powered tools for internal and client-facing offensive security use cases. - Develop systems that support agentic pentesting workflows, red team operations, and security automation. - Build AI-assisted code review and analysis workflows focused on identifying vulnerabilities and high-risk patterns. - Turn real security testing problems into scalable software. - Research and production delivery: Evaluate models, frameworks, and workflows related to applied AI in offensive cybersecurity. - Prototype quickly, validate what works, and productionize the strongest ideas. - Balance the speed of experimentation with engineering quality, reliability, and maintainability. - Contribute to the technical direction of AI-enabled offensive security capabilities. - Engineering and collaboration: Build and maintain backend services, integrations, and automation pipelines. - Work with LLM orchestration, RAG pipelines, CI/CD, and supporting infrastructure. - Collaborate closely with pentesters, consultants, and technical leadership. - Improve the performance, observability, and robustness of the systems you build. ### Required skills - Minimum of 4 years of proven experience building production-grade software systems. - Strong programming skills in Python and/or other backend-oriented languages. - Experience with modern software engineering practices, including CI/CD. - Familiarity with LLM-based applications, orchestration workflows, or RAG systems. - Ability to move from ambiguous ideas to working, dependable tooling. - Strong problem-solving skills and sound engineering judgment. - A builder mentality, with the ability to combine experimentation with disciplined execution. - Strong communication skills and the ability to work across engineering and security teams. - Must be located in Portugal and legally employable there. ### Nice to have - Experience building AI-enabled products, developer tools, or internal platforms. - Familiarity with offensive security, application security, pentesting, or red team workflows. - Exposure to fuzzing, code review, vulnerability research, or secure software engineering. - Experience with Go, Rust, TypeScript, containers, or cloud infrastructure. - Experience working in a startup and fast-moving technical environment. - Prior experience in cybersecurity services or security product companies. ### KPI and success metrics - Delivery of production-ready AI tooling. - Speed and quality of experimentation-to-production cycles. - Adoption and impact of tooling across internal teams and client-facing workflows. - Reliability, maintainability, and usability of deployed systems. - Contribution to Blaze's offensive security capabilities and technical differentiation.
