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.

This is an opportunity to join at the foundational stage of a multi-year transformation.

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
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:

CRM (Insightly) Implementation

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

Middleware / Integration Layer

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 (Server less preferred)

Collaboration + Product

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

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)
Strong debugging, performance optimization, and architectural skills
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- 8 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.
