Full-Stack Developer — Build the AI Engine of a Fast-Growing Solar Company Solana Energy | Remote (AU or NZ) | Part-time → Full-time | $50–65/hr starting The short version We're rebuilding Solana Energy — a Newcastle-based solar, battery and EV company on track to triple revenue in 12 months — into an AI-powered, automation-first business. We need one sharp developer to help us build it. You'll work directly with the founder and tech lead (no middle management, no ticket factory) on real, high-impact projects: an interactive solar design tool, AI-powered sales automation, CRM integrations, a centralized "company brain" using Claude and Model Context Protocol, and the data pipelines that connect it all. Start part-time (15–25 hrs/week). Prove the fit over 2–3 months. Move into a full-time lead developer role with a salary jump and equity discussion on the table. What you'll actually build, in your first 90 days The Solana Design Studio: a futuristic web-based solar/battery/EV configurator with an AI-style intake, dynamic ROI engine, and live system design (React prototype already exists — you'll productionize it, wire it to our Pylon design tool's API, and ship it) Lead capture → CRM automation: every completed configuration drops as a pre-qualified deal into our [login to view URL] Virtual Call Centre board, with notifications routed to the right sales rep AI-powered customer follow-up: Claude-powered email sequences for quote follow-ups and post-installation nurturing Live business dashboards: real-time conversion tracking across the sales funnel — speed-to-lead, sat rate, sat-to-sold, payback periods The foundation of our central AI system: a Supabase + pgvector data layer that unifies Gmail, Google Drive, [login to view URL], Xero, and JustCall into one Claude-queryable knowledge base This isn't theoretical work. Every project ships to a live business with real revenue impact. Who you are Required: 2+ years building production web apps with React (the stack we use) and Node.js or Python Comfortable with APIs and webhooks — you've integrated third-party platforms before (Stripe, Twilio, anything with OAuth) Solid with databases — Postgres preferred, comfortable with SQL and basic schema design You can read someone else's code and improve it without rewriting from scratch You ship — you've taken at least one thing from idea to live production Strongly preferred (any of these moves you to the top of the pile): Built or worked inside a CRM or sales pipeline tool ([login to view URL], HubSpot, Salesforce, Pipedrive) Experience with Zapier, [login to view URL], or n8n automations beyond beginner level Worked with AI APIs — OpenAI, Anthropic Claude, or similar — in real production code, not just demos Background in or genuine interest in digital marketing or sales funnels (you understand why speed-to-lead matters, what a conversion rate is) Familiar with Supabase, Vercel, or similar modern deployment platforms Bonus (don't worry if not): Experience with Model Context Protocol (MCP), LangChain, or agent frameworks Solar industry exposure — or you want it You've shipped something you're genuinely proud of (send the link) Who you are as a person You think in systems, not just code. When you build a feature, you instinctively ask how it scales, where it breaks, what it depends on. You're a self-starter. Solana's founder works remotely from New Zealand. You won't be hand-held. You'll be trusted with real ownership early and expected to communicate clearly when you're stuck. You're curious about business, not just technology. You want to understand why we're building something, not just what. You ship fast and iterate. Perfectionism that delays releases is not a virtue here.

Hi, I've built full-stack AI systems for energy and hardware companies before. You need someone who speaks both Python and hardware — that's rare, and that's us. I noticed you're connecting AI with solar infrastructure. We've handled similar integrations between backend systems and field devices. I have delivered 1500+ web and mobile projects over 14+ years — happy to share relevant examples. Let's talk through your AI engine architecture. Thanks, Hasan

As an experienced AI and Cloud Developer, I believe I bring all the necessary skills and expertise you need to build Solana Energy into an AI-powered business. Throughout my career, I've successfully developed scalable backend systems and AI-powered platforms for companies just like yours. I'm not just a developer; I'm a systems thinker. This means that when I build features or design architectures, scalability, resilience, and dependencies are always at the forefront of my mind. In terms of the technologies we'll be using, I have extensive experience with Python - having built multiple production web apps using frameworks such as FastAPI - and Node.js which will be fundamental to utilize the existing stack at Solana Energy. My proficiency in React will ensure I can seamlessly wire your prototype for the Solana Design Studio to your Pylon design tool's API. Moreover, having integrated various third-party platforms like Stripe and Twilio sets me up comfortably for leveraging your existing tech stack as well as maximizing the value from tools like Monday.com. My strong database skills especially with Postgres and SQL allow me to efficiently design schemas and read someone else’s code for improvements without rewriting everything from scratch - thereby providing a significant time advantage. Best, sardar (ceo MHTechFusion)

Hi, This is Elias from Miami. I checked the details and understand you're not looking for someone to build isolated features—you're building an AI-first operating system around a growing solar business, with the design studio, CRM automation, reporting, and company knowledge base all connected through a shared data layer. The real challenge here is creating systems that work together rather than a collection of disconnected automations. Projects like this usually succeed or fail based on data flow, API reliability, and how easily new tools can be integrated as the business grows. I've worked on SaaS platforms involving React, Node.js, AI integrations, workflow automation, Supabase, CRM systems, and business process automation. I have a few questions to get a better understanding: Q1 – Is the existing React prototype already connected to Pylon's API, or is that integration still to be built? Q2 – Are you currently using Supabase as the primary database, or is migration part of the roadmap? Q3 – For the AI knowledge base, are you planning real-time synchronization with external systems or scheduled ingestion workflows? I'd be happy to discuss the details and suggest the best approach for implementation. Looking forward to hearing from you.

Hi there, I see you're looking for a full-stack developer to build an AI engine for Solana Energy. Creating an AI engine for solar applications requires a solid understanding of both AI development and the technical aspects of solar energy systems. I can utilize Python for the AI components while handling the backend with Node.js and PostgreSQL for data management. Balancing performance and scalability will be key, especially as your company grows. I'd start by analyzing your current data and requirements to define how the AI engine can best serve your needs, then set up the initial architecture. Q1: What specific functionalities do you envision for the AI engine? Q2: Are there any particular data sources or APIs you want to integrate? Q3: What is your timeline for the project milestones? Let’s collaborate to bring your vision to life.

Hi, This sounds like a role where you need a full-stack developer who can think through the business workflow, not just build isolated features. I can work across React, Node.js, Python, PostgreSQL, Supabase, APIs, webhooks, CRM automation, AI APIs, dashboards, and production deployment, with a focus on shipping useful systems quickly and improving them from real business feedback. The most important part here is building the Solana Design Studio and CRM automation as one connected flow, so completed configurations become qualified leads, trigger the right follow-up, and feed reporting without manual admin. I have worked on SaaS, automation, dashboard, API integration, AI-assisted workflow, and business platform projects where clean systems thinking mattered as much as the code. I am comfortable starting part-time, working directly with a founder or tech lead, reading existing code, improving it without unnecessary rewrites, and communicating clearly while moving fast. I can help turn the current React prototype and automation ideas into production systems that support real sales, operations, and long-term AI infrastructure.
