We are currently in a transformative phase, moving from “manual intervention and firefighting” to an era of Systematic Resilience.Our mission is to build “Unbreakable Systems”—platforms that don’t just survive failures but absorb them, self-heal, and scale with the business calmly and predictably. We are looking for engineers who want to stop “fixing” and start “architecting” at the highest level.THE PURPLLE WAY: AI-NATIVE ENGINEERINGWe believe that as a business scales, technology shouldn’t become more fragile. We have redesigned our entire engineering lifecycle to be AI-native, moving away from manual toil toward a world of intelligent, self-governing systems:• Velocity without Fear (70% AI-Assisted): We ship fast because we’ve built the safety nets to do so. You won’t just be a “coder”; you will be a system architect. We empower our engineers to use AI for the heavy lifting of development—aiming for 70% of Pull Requests to be AI-assisted—so you can focus on complex logic and high-level architecture.• Built-in Guardrails & Self-Healing Systems: Security and quality aren’t “extra steps”—they are baked into our “Golden Paths.” We build systems that use AI for automated rollbacks and deterministic fallback logic, ensuring the platform absorbs mistakes automatically and remains resilient under pressure.• Intelligence by Default (Zero-Toil Operations): We embed AI across the entire lifecycle—Build,Test, Detect, and Operate. By utilizing AI agents to eliminate “Ops Toil,” we’ve created an environment where anomaly detection and incident diagnosis happen in minutes, not hours.• Predictable Economics & Growth: We treat cloud costs and system performance as core engineering disciplines. Every engineer at Purplle understands the “unit economics” of their code, ensuring our infrastructure scales as efficiently as our business.THE PURPLLE ENGINEER: MINDSET & IMPACTWe aren’t looking for “feature factories”; we are looking for owners of a resilient ecosystem. At Purplle, your success is defined by your mindset and the tangible impact you have on our platform:• The Systems Thinker (Quality & Resilience): You hate fixing the same bug twice. You’d rather build a “self-healing” mechanism than perform a manual fix. Your goal is to maintain a Change Failure Rate of <1.5% and help us reach a state of fewer than 2 Sev-1 incidents per quarter.• The AI-Fluent Architect (High Velocity): You are already using AI tools to 10x your own productivity. You leverage these tools to drive a cycle time of <4 hours and maintain a high frequency of dailydeployments, moving code from commit to production with total confidence.• The Data-Informed Engineer (Economic Discipline): You care about the “why” behind the code. You understand that latency and cloud spend are engineering disciplines, and you optimize your infrastructure so that our cost-per-order remains predictable as we scale.• The Proactive Collaborator (Security & Governance): You thrive in a cross-functional environment (Eng, Data, DevOps, Security). You take ownership of the “Golden Path,” ensuring 100% of your repositories are gated and that zero critical vulnerabilities ever reach our production environment.YOUR SPECIFIC MANDATEIn this role, you will be directly responsible for:• AI-Native Velocity: Lead the 70% AI-assisted PR mandate by mastering Cursor, Copilot, and Claude to accelerate delivery of Node.js (NestJS) and Golang microservices—while keeping human intelligence focused on high-level system design and architecture decisions.• Unbreakable Backend Architecture: Architect high-throughput, event-driven microservices using Kafka and Redis, embedding resilience patterns like circuit breakers, health checks, and fallback mechanisms to handle massive traffic spikes without manual intervention.• Data & Performance Ownership: Own the ‘unit economics’ of the data layer—optimize MySQL and MongoDB queries, design efficient schemas, and ensure sub-second p99 latencies with predictable infrastructure costs on GCP.• End-to-End Golden Path Ownership: Drive features from design docs to Kubernetes deployment, ensuring high reliability through strong engineering practices and maintaining low change failure rates and minimal Sev-1 incidents.• API & Service Design Excellence: Build clean, versioned, and backward-compatible APIs and modular microservices with a strong focus on maintainability, scalability, and clear service contracts.• Cloud-Native Operations & Observability: Design and operate services on Kubernetes with robust logging, monitoring, and alerting; proactively debug production issues and ensure high availability.• Scalability & Cost Efficiency: Continuously optimize system throughput, fault tolerance, and infrastructure utilization to support high growth while maintaining strict control over cloud costs.• Technical Leadership & Collaboration: Lead design decisions, write clear RFCs, mentor engineers, and collaborate closely with Product, Frontend, Data, and DevOps teams to drive high-quality outcomes.• Core Engineering Excellence: Apply strong fundamentals in distributed systems, concurrency, and data structures, combined with sharp problem-solving, debugging, and communication skills.TECH STACK• Languages & Frameworks: Node.js (NestJS / Express), Golang• Data & Messaging: MySQL, MongoDB, Redis, Kafka, Aerospike, ElasticSearch• Infrastructure: Kubernetes, GCP / AWS, Docker• Observability: Prometheus, Grafana, OpenTelemetry• AI Productivity: Cursor, Claude, GitHub CopilotEXPERIENCE• SDE1 — 1–2 years of backend engineering experience• SDE2 — 2–5 years; strong ownership of production systems• SDE3 — 5–7 years; proven track record of designing distributed systems at scaleWHY JOIN PURPLLE TECH?You will be joining a team that is actively moving away from the “chaos” of traditional scaling. At Purplle, we are building a tech culture that is “Operational, not Aspirational.”We provide the tools, the AI-first environment, and the “Golden Paths” to let you do the best work of your career. If you want to build intelligent, unbreakable systems that scale with confidence, your journey starts here.About Company Founded in 2011, Purplle has emerged as one of India’s premier omnichannel beauty destinations, redefining the way millions shop for beauty.
