Job Description

About the job Senior AI Engineer (Founding Team) Location: Bengaluru (Preferred) / Remote (India) Experience: 3–8 Years Type: Full-time About PurpleLens PurpleLens is building the next generation of offensive cybersecurity using Agentic AI. We believe security shouldn't be based on theoretical vulnerabilities, it should be based on evidence. Our AI agents continuously think and act like ethical hackers, discovering assets, validating exploitable attack paths, and providing organizations with continuous, evidence-based risk intelligence. Our platform combines autonomous AI agents with human expertise to help organizations understand: Their assets Their attack surface Their exposure Their real business risk We're an early-stage startup backed by customers, solving one of the most challenging problems in cybersecurity. If you enjoy building products from scratch, working with cutting-edge AI systems, and shipping quickly, we'd love to talk. The Role We're looking for a Senior AI Engineer who enjoys building products, not just models. This is a hands-on engineering role where you'll own end-to-end product capabilities, from idea to production. You'll design intelligent agent workflows, integrate LLMs with security tooling, build scalable backend services, and ship customer-facing features independently. This is not a role where you'll be working on isolated ML experiments. You'll be responsible for delivering production-ready AI capabilities that customers use every day. You'll work directly with the founders and become a key member of the engineering team. What You'll Do Own complete product features from design through deployment. Design and build production-grade AI agents and autonomous workflows. Build systems around LLMs, retrieval, memory, planning, and orchestration. Integrate AI agents with cybersecurity tools, APIs, and external systems. Optimize AI systems for accuracy, latency, reliability, and cost. Build scalable backend services and APIs. Work closely with founders to rapidly convert customer feedback into product. Take responsibility for engineering decisions and product quality. Contribute to architecture and technical direction as the company grows. What We're Looking For Required 3+ years of software engineering experience. Previous startup experience is mandatory. Ideally part of a founding or early engineering team. Proven ability to independently own and deliver complete product features. Strong Python engineering skills. Experience building production applications using modern AI frameworks. Experience with LLM APIs and agent frameworks. Strong backend engineering fundamentals. Experience deploying and operating cloud-native applications. Comfortable working in ambiguity and moving fast. Strong product mindset and ownership. Bonus Points Cybersecurity experience. Offensive security or penetration testing knowledge. Experience building AI agents for security workflows. Knowledge of attack techniques, reconnaissance, vulnerability discovery, or exploit development. Experience with Kubernetes, Docker, cloud infrastructure, and distributed systems. Experience with MCP, tool calling, RAG, memory systems, and multi-agent architectures. Contributions to open-source AI or cybersecurity projects. What Makes Someone Successful Here You're someone who: Loves building products from zero to one. Doesn't wait for detailed specifications. Can independently solve complex engineering problems. Enjoys shipping every week. Takes ownership rather than waiting for instructions. Learns new technologies rapidly. Thrives in a fast-moving startup environment. Why Join PurpleLens Build foundational technology at the intersection of AI and cybersecurity. Work directly with experienced founders solving real customer problems. Own meaningful parts of the product from day one. Help define the technical direction of the company. Learn and work with cutting-edge Agentic AI architectures. Opportunity to grow into a technical leadership role as the company scales. Our Tech Stack Python FastAPI LLMs (OpenAI, Anthropic, open-source models) Agentic AI frameworks Docker & Kubernetes MongoDB Cloud Infrastructure (AWS/Azure) GitHub Actions Modern AI tooling and orchestration frameworks How We Hire We're looking for builders with a strong track record of ownership. Our interview process focuses on: Engineering depth Product thinking AI system design Hands-on coding Ownership and execution Startup mindset If you've built products that customers love and enjoy solving hard engineering problems, we'd love to hear from you. Apply by sending your resume, GitHub profile (if available), and a brief note describing a product feature you've personally owned end-to-end.
