Job description

Job Description

You will design and build foundational pieces of our agentic security platform, from AI agentsthat investigate real incidents to the distributed systems that keep them fast, safe, and reliable fordozens of security teams. You’ll work closely with founders, product, and security experts toturn messy real‑world Security operations like SOC, ThreatHunt, Pentest, Security devicemanagement etc. into elegant, scalable product experiences.You may own one vertical deeply or work across several in the same project when needed.

Inyour first few months, you will:

• Own end-to-end design & delivery of features you take up
• Ship platform, agent, or integration capabilities at high velocity
• Collaborate not just with product & engineering leaders, but also sales, marketing, andcustomer-facing teams to shape what we build and why
• Deploy features into live production environments, with ownership beyond delivery —including monitoring, stability, and iteration post-launch

What You’ll Work On

Your work may include:

AI + Agent Systems

• Building agents for SecOps → Develop autonomous agents that investigate alerts, triagethreats, respond, and close cases with minimal human input.
• Designing tool schemas, workflows, memory stores for agents → Define structuredtool interfaces, execution paths, and long-term memory for reasoning across tasks.
• LangGraph based flows for agents (or another agentic framework) → Build multistep agent workflows with branching logic, retries, validation, and conditional toolcalling.
• Safe-execution loops with guardrails, policy layers, and approvals → Ensure agentsoperate within risk boundaries using policy controls and human-review checkpoints.
• Building high-scale, multi-tenant backend systems→ Architect services that securelysupport many customer environments in parallel without resource collisions.
• Designing ingestion, indexing & agent memory retrieval layers → Build pipelines that ingests customer security data, store it as agent-accessible memory, and retrieve relevantcontext instantly.
• Implementing evaluation pipelines & scoring frameworks for agents → Measureagent quality using scoring metrics, test harnesses, regressions, and continuous feedbacksignals.
• Distributed execution, traceability, observability & data quality → Enable highvolume workloads with strong logging, metrics, monitoring, and correctness guarantees.

Security & Product Engineering

• Attack simulation & golden dataset creation → Generate controlled attack scenarios to evaluate agents and build benchmark datasets for continuous improvement.
• SIEM, SOAR, EDR, NDR style integrations → Integrate with enterprise securityproducts, ingest telemetry, push remediation actions, and unify signals across the stack.

This is a place where engineers ship, own, iterate, observe, and improve.

Requirements

You’ll Thrive Here If You

• Think in systems
• Like solving undefined problems, not following tickets
• Understand distributed systems + AI fundamentals deeply
• Enjoy reading RFCs, research papers & learning new techMust Have
• Strong backend development experience (Python/Go/Node preferred)
• Solid understanding of distributed systems fundamentals
• Experience with microservices, async execution, event streams
• Familiarity with cloud infra (AWS/GCP/Azure), containers, CI/CD• Ownership mindset — ability to take a problem from zero → shippedBonus / Great to Have
• Worked on SIEM, SOAR, EDR platforms OR cyber security data pipelines
• Knowledge of RAG, vector DBs, embeddings, Eval frameworks
• Obsessed with writing clean tests, docs, and elegant abstractions

PS: WE ARE VERY PARTICULAR ABOUT YOUR PEDIGREE. WE WILL PREFER IF YOU HAVE STUDIED FROM IIT'S, BIT'S, VIT, AND NIT

Why Join Us?

• Build an AI-first SOC platform from scratch
• Work directly with founders/leaders on architecture, product direction.
• Ship fast, learn fast, own deeply
• Be there early — where impact compounds
