About Us

We are a dynamic and rapidly expanding residential solar installation business based in California, USA. Our mission is to make clean energy accessible to homeowners and accelerate the adoption of solar power throughout the United States. After bootstrapping our early growth, we are investing in the systems that will take us through our next stage. We're looking for a versatile, senior full‑stack engineer to help build and optimize the platforms that drive our business.

Role Overview

You will be the technical lead responsible for implementing Insightly CRM pipelines, custom fields, automations, and API integrations; designing and building a scalable middleware/API layer; working with operational heads to convert business processes into robust system workflows; and acting as the glue between CRM, web app, and external partner systems (dialers, financing providers, proposal management and scheduling tools, etc.).

You will be an experienced, senior, hands‑on engineer with architectural autonomy and significant influence over Lytegen's technology direction. This is a greenfield opportunity to help define the architecture, build core integrations, and ship real tools used daily by hundreds of internal and external users and would be ideal for an engineer who enjoys solving end‑to‑end business workflow problems, not just writing code.

Key Responsibilities

• Configure Insightly objects, pipelines, automations, and permissions.
• Build custom fields and structured workflows for leads, proposals, NTP, projects, permitting & installations.
• Set up and manage Insightly webhooks and API integrations.
• Optimize CRM usability for setters, schedulers, closers, and project teams.
• Design system integrations between Insightly and external tools.
• Build REST APIs, background workers, webhooks, and syncing logic.
• Implement authentication, API rate‑limit handling, and robust error logging.
• Set up a clean, maintainable architecture (Serverless preferred).
• Translate complex business workflows into technical designs.
• Participate in solution design workshops with US/UK stakeholders.
• Handle documentation, schema design, API contracts, and release planning.
• Assess technical feasibility, effort, and impact before implementation.
• Strong debugging, performance optimization, and architectural skills.

Skillset

• Strong proficiency in full stack development (NOSQL, React or Next.js, Lambda).
• Solid understanding of REST APIs, authentication, and integration patterns.
• Experience working with CRMs (Insightly preferred, Salesforce/HubSpot acceptable).
• Cloud experience (AWS preferred).
• Ability to understand sales workflows, operations processes, and multi‑stage pipelines.
• Strong communication—clear documentation, structured thinking, and internal stakeholder coordination.
• Ability to convert ambiguous requirements into structured system designs.

Experience

• 4+ years of full‑stack engineering experience.
• Must have delivered at least one end‑to‑end CRM or workflow automation project.
• Must have built API‑driven backend services.
• Bonus: Experience in solar, field service, fintech, or operations‑heavy businesses.
• Bonus: Experience with Insightly specifically (otherwise willingness to upskill quickly).

Why Join Us?

• Opportunity to make a significant impact in a rapidly growing company.
• A chance to design and own a mission‑critical system from ground zero in a collaborative and supportive work environment.
• Opportunity to grow your skills, advance your career, and build a mission‑critical system from ground zero.
• Chance to work on cutting‑edge greenfield projects and contribute to a sustainable future.
