Technical Lead / Solution Architect (Cloud Eventing & Notifications) - Safety / Rtls Mvp

Location : Noida (EST overlap 3-4 hours)

Team : Platform Engineering - Safety & Presence

Employment Type : Full-time

Position Summary

Lead a small squad (2 senior full-stack engineers with shared DevOps / QA) to deliver a cloud-first, private-site safety / presence MVP in ~3 months and evolve it to a production ready system in ~6–7 months.

Own architecture, security, and delivery for a real-time eventing & notifications platform (web push / SMS / email) fed by gateways and badges. LoRaWAN / ChirpStack is learn-on-the-job expectation, to reach hands-on proficiency within 2–3 weeks.

Essential Functions (Role Responsibilities)

Architecture & Delivery Ownership : Define and deliver the end-to-end pipeline (gateway → ingest → normalize → zone logic → multi-channel notifications → audit) with SLIs / SLOs.

• Cloud-First Private LNS : Stand up and operate a private Network Server (e.G., AWS IoT core, Things Stack, ChirpStack or another service on VMs / k8s) in the VPC;

prefer Basics Station (TLS), support Semtech UDP.

Data & API Contracts : Author OpenAPI specs, versioning strategy, and backward-compatible interfaces for a responsive webapp and / or PWA and partner systems.

Security & Compliance : Enforce TLS, KMS-backed secrets, HMAC-signed webhooks, VAPID keys for web push, PII minimization, access controls.

Productization Path : Plan and sequence accounts / RBAC, tenant / site model, licensing / entitlements, upgrades / rollback, diagnostics, and supportability.

drive outcomes with crisp ADRs / runbooks.

maintain review gates and quality bars.

Essential Tasks (Day-to-Day)

create gateway onboarding templates (URIs, certs / keys), cellular fallback, buffering, and monitoring checklists.

Implement ingest services (MQTT / webhook) with idempotency, retries / backoff, correlation IDs, and structured logging.

validate via walk tests.

Build / oversee notification orchestration (web push via Service Workers / VAPID, SMS via MSG91, email via SES / SendGrid) with delivery receipts and audits.

Guide the PWA operator console : floor-plan overlay, live feed, ack / escalation, filters / search, and “Reset Site” tooling.

Establish observability : dashboards for p95 SOS latency, join / uplink confirm rates, gateway online %, notification success.

lead readiness reviews for Demo → Pilot → GA.

manage risk register and cut scope when needed to hit dates.

(Multi region system architecture design know-how)

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 or The Things Stack, AWS IoT Core), Basics Station vs Semtech UDP, 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, correlation / traceability, HA / backup / restore.

Security Mindset : Key / 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 measurable outcomes (latency, delivery success).

Learning Agility : Ability to master LoRa fundamentals in a short period and translate them into robust runbooks.
