About Nexa Consultancy

Nexa Consultancy Inc is a Surrey, British Columbia (Canada) based company that helps other businesses set up everything they need to run and grow: dashboards, CRM, automation, reporting and marketing. We run our own operations on GoHighLevel, n8n and Make.com and build the same systems for our clients. Because this is ongoing work for our clients, we are looking for long-term people who will grow with us, not short-term contractors. We are hiring a full-time, remote Automation Developer in India to own this stack end to end.

What you will do

• Build, maintain and document automations in n8n and Make.com (lead intake, follow-up sequences, appointment booking, WhatsApp and email notifications, reporting).
• Own our GoHighLevel setup: pipelines, workflows, custom fields, calendars, forms, funnels and integrations.
• Connect tools through REST APIs and webhooks (GoHighLevel, Google Sheets, Gmail, WhatsApp, Meta lead forms, Cloudflare Workers, AI APIs).
• Write small scripts and serverless functions (JavaScript or Python) where a no-code step is not enough.
• Monitor scenarios, fix failures fast, and keep an eye on run quotas and costs.
• Build dashboards and reports so the team can see leads, follow-ups and conversions without asking.
• Turn a plain-English request from the Director into a working, tested automation.

What we are looking for

• 2 to 5 years of hands-on automation or integration work, with real n8n and Make.com scenarios you can show.
• Solid GoHighLevel experience (workflows, pipelines, snapshots, API). Other CRMs are a plus.
• Comfortable with REST APIs, webhooks, JSON, OAuth and debugging failed runs.
• Working JavaScript or Python for custom code steps; SQL or Google Sheets formulas are a plus.
• Clear written English. You will document what you build and explain it to non-technical teammates.
• Self-directed. This is a remote role with a small team; you will own outcomes, not just tickets.

Nice to have

• Cloudflare Workers, Zapier, Airtable, Notion, WhatsApp Business API, Meta or Google Ads integrations, OpenAI or Claude APIs.

Work setup

• Full-time, remote, from India.
• Long-term role. We want someone who stays, learns our clients' businesses and grows with the team.
• Must overlap with Canadian Pacific Time business hours for part of each day; exact schedule agreed at offer.
• Your own laptop, reliable high-speed internet and a smartphone are required.

Compensation

• INR 80,000 to 1,10,000 per month, based on experience.
