Full-Stack Engineer (Energy MVP) - Part-time - Worldwide

About Dawn Energy

Dawn Energy is building the central brain for home energy in Ontario. Our Energy Management System (EMS) will connect to smart devices, optimize their use based on pricing and production data, and give homeowners one intuitive interface for control, savings insights, and upgrade pathways.

We’re starting with an MVP: a thin but functional slice across all layers, designed with our principle of “build once, extend forever.”

Technical Stack (Preferred)

• Frontend: Next.js 14 (App Router), TypeScript, Tailwind + shadcn/ui, Zustand, React Hook Form
• Backend: Fastify (TypeScript), API-first microservices (calculation, EMS integration, CRM)
• Database: PostgreSQL
• Other: Docker-compose for local dev, deployable to cloud
  (If you have other strong stack preferences, open to discussion — what matters is scalability and clean architecture.)

About You

• Full-stack capable – can own both backend logic and frontend flows.
• Integration experience – confident with OAuth, APIs, polling, and token refresh.
• Product-minded – translate business objectives into lean, scalable code.
• Climate-motivated – you care about clean energy and want your work to accelerate electrification.

Bonus points if you’ve:

• Built an EMS, IoT integration layer, or device control logic before.
• Worked with HVAC APIs, solar, EVSEs, or battery integrations.
• Done CRM integrations or UTM/analytics tracking.

Engagement Details

• Collaboration: Direct with founder, flexible + remote.
• Timeline: MVP delivery as a single scoped project, with potential to extend into future phases (multi-device, triggers, full dashboards).

The Project Scope (MVP)

Pillar 1 – Lead Gen
 Two entry points:
o “Connect My Data” → OAuth flow
o Segmentation form (3–5 homeowner fields)
 Backend triggers EMS calculation logic → outputs static electrification options.
 Lead data (incl. UTMs) sent into CRM (Klaviyo via Make Webhook).
 Event tracking for submissions & success.
Pillar 2 – Remote Integration
 Integrate Ecobee thermostat only (OAuth).
 Token storage + refresh logic.
 Poll every 5 minutes: temp, mode, setpoints, hvacRunning.
 One command type: setHold (with guardrails).
 Minimal internal QA page/log output for verification.
Pillar 3 – Smart Dashboard (Lite)
 For MVP: internal QA only (not consumer-facing).
 Future scope: unified multi-device dashboard, history, automation.

Definition of Done (MVP)

 Homeowner can submit info → EMS outputs upgrade list.
 CRM captures all lead data with correct fields + UTMs.

 Ecobee connects via OAuth, polls successfully, sends setHold.
 Stable, deployable environment with secure token handling.
