Job Description
Full details about the role and requirements
Yukerja Summary
The Full Stack Engineer role at Flatgigs is curated from Himalayas (category Teknologi & IT). This role is marked as remote — check timezone and location requirements on the official listing. Yukerja.com is not the employer — applications are handled on the official source site.
The Senior Full Stack Engineer builds the AHOY IoT platform end to end—from device telemetry ingestion and AWS infrastructure to the real-time web dashboard. We are hiring two full-stack engineers who each own complete vertical slices of the product. This model ensures speed and resilience at founding stage; each engineer takes features from sensor to dashboard.
The trade-off is a very high bar: true backend engineering and real frontend craft in the same person. As the more senior hire, you will also act as technical lead, owning the platform architecture, AWS infrastructure, and key technology decisions.
Requirements
Key Responsibilities
Backend
- Core Services: Build multi-tenant services from scratch: device registration/auth, alert/rule engines, notifications, and device shadow (last-known-state) services.
- Data Pipelines: Implement the MQTT ingestion path (EMQX broker), normalize telemetry, and persist it to time-series storage and Aurora PostgreSQL (with strict row-level security).
- APIs & Real-Time: Develop versioned REST APIs (OpenAPI) and real-time delivery paths via WebSockets for high-concurrency dashboard updates.
Frontend
- App Development: Build the platform web application in Next.js + TypeScript, including monitoring dashboards, onboarding wizards, and multi-tenant admin portals.
- High-Frequency Data: Render live telemetry and time-series visualizations (line, gauge, maps) without lag, page refreshes, or memory leaks.
- UX & UI Craft: Make independent UX choices in the absence of a designer; maintain a reusable component library from Day 1 with i18n scaffolding (Arabic RTL support).
Architecture
- Infrastructure as Code: Provision and maintain AWS environments (UAE region me-central-1 for data residency) using Terraform. No click-ops.
- Scale & CI/CD: Set up GitHub Actions CI/CD pipelines, operate core infrastructure (Kafka, Redis, InfluxDB), and define horizontal scaling strategies for hundreds of thousands of devices.
- Remote Discipline: Work autonomously with proactive documentation (ADRs, runbooks) and a minimum 4-hour daily overlap with UAE working hours.
Must-Have Requirements
- Experience: 5–9 years of full-stack engineering shipping production applications (portfolio required showing deep execution on both sides).
- Expert Frontend: React/Next.js with TypeScript; proven experience handling high-frequency data streams and virtualized lists via WebSockets. (Non-Negotiable)
- Strong Backend: Production services in Node.js/TypeScript and/or Python; strong data modeling and relational performance (PostgreSQL). (Non-Negotiable)
- IoT & Messaging: Genuine literacy in MQTT protocols (topics, QoS, LWT) and device connectivity concepts. (Non-Negotiable)
- Cloud & DevOps: Hands-on AWS infrastructure deployment and GitOps-driven Terraform workflows.
- Data Viz: Proficiency in D3.js, ECharts, or similar to build custom chart types and geospatial device maps.
Nice to Have
- Go (Golang) for high-throughput backend services.
- Production-scale self-hosted MQTT brokers (EMQX, HiveMQ) beyond standard AWS IoT Core.
- Geospatial frameworks (Mapbox GL JS, Leaflet, Deck.gl).
- Kafka/MSK stream processing; Keycloak for RBAC/MFA.
- Industrial vertical exposure (cold chain, telematics, smart buildings, predictive maintenance).
