Role Title : Lead Engineer – Safety & Presence Platform
Location : Noida (with 3–4 hours overlap with EST)
Team : Platform Engineering – Safety & Presence
Employment Type : Full-time
Position Summary
Lead a small, high-impact squad (2 senior full-stack engineers with shared DevOps / QA support) to :
- Deliver a cloud-first, private-site safety & presence MVP in ~3 months.
- Evolve it into a production-ready system in ~6–7 months.
You will own the architecture, security, and delivery of a real-time eventing & notifications platform (web push / SMS / email) powered by gateways and badges.
Experience with LoRaWAN / ChirpStack is not mandatory;you are expected to learn on the job and reach hands-on proficiency within 2–3 weeks.
Role Responsibilities (Essential Functions)
Architecture & Delivery Ownership
Define and deliver the end-to-end pipeline : gateway → ingest → normalize → zone logic → multi-channel notifications → audit.Establish and track SLIs / SLOs for reliability and performance.Cloud-First Private LNS
Stand up and operate a private LoRa Network Server (e.G., AWS IoT Core, The Things Stack, ChirpStack, or another service on VMs / k8s) inside a VPC.Prefer Basics Station (TLS) while also supporting Semtech UDP.Data & API Contracts
Author and maintain OpenAPI specifications and a versioning strategy.Design backward-compatible APIs for a responsive web app and / or PWA and partner systems.Security & Compliance
Enforce TLS everywhere, KMS-backed secrets, HMAC-signed webhooks, VAPID keys for web push.Apply PII minimization and appropriate access controls.Productization Path
Plan and sequence : accounts and RBAC, tenant / site model, licensing and entitlements, upgrades / rollback, diagnostics, and supportability.Team Leadership
Coach two senior full-stack ICs.Collaborate closely with in-house DevOps and QA.Drive outcomes with crisp ADRs and operational runbooks.GenAI-Augmented Delivery
Use GenAI tools for scaffolding code, tests, documentation, and KT summaries.Maintain strong review gates and quality bars.Day-to-Day Responsibilities (Essential Tasks)
Stand up the cloud LNS and create gateway onboarding templates (URIs, certs / keys), cellular fallback, buffering, and monitoring checklists.Implement ingest services (MQTT / webhook) with idempotency, retries with backoff, correlation IDs, and structured logging.Define event envelopes (SOS / telemetry) and BLE-assisted zone logic (RSSI bucketing / smoothing, confidence scoring);validate via walk tests.
Build and oversee notification orchestration :Web push via Service Workers / VAPIDSMS via MSG91Email via SES / SendGridwith delivery receipts and audits.Guide the PWA operator console : floor-plan overlay, live feed, acknowledgment / escalation flows, filters / search, and “Reset Site” tooling.Establish observability : dashboards for p95 SOS latency, join / uplink confirm rates, gateway online %, and notification success.Create and maintain ADRs, runbooks, and installer / onboarding documentation;lead readiness reviews for Demo → Pilot → GA.
Conduct design and PR reviews;unblock engineers;manage a risk register and cut scope when needed to hit dates.
Educational Qualifications & Experience
Required
Bachelor’s or Master’s degree in Computer Science, Electrical / Computer Engineering, Information Systems, or equivalent practical experience.7+ years building cloud or event-driven platforms (Node / TypeScript, Go, or C#) with Postgres (or similar), message / broker patterns, and production APIs (OpenAPI).Demonstrated experience building and operating SaaS products (production SLIs / SLOs, on-call / incident playbooks, release management).Preferred
Exposure to LoRaWAN (ChirpStack, The Things Stack, AWS IoT Core), Basics Station vs Semtech UDP, and gateway onboarding at scale.Experience with web push (Service Workers / VAPID), SMS / email providers, BLE / beacon-driven zoning, and time-series stores (Timescale / ClickHouse).Background in multi-tenant architecture, entitlements / licensing, and customer onboarding for B2B SaaS.Core Competencies
Systems Design & Reliability :Idempotency, rate limiting, pagination, backoff strategies, correlation / traceability, high availability, backup / restore.Security Mindset :Key and secrets management, TLS, HMAC, authN / Z, privacy-by-design.Delivery Leadership :Scope control, risk management, stakeholder communication, crisp documentation.Customer Empathy :Operator-first UX, fast incident triage, and focus on measurable outcomes (latency, delivery success, etc.).Learning Agility :Ability to master LoRa fundamentals quickly and translate them into robust runbooks.Tools & Technologies (Nice to Have;Not All Required Day One)
