Hey there! 👋

Optemization is growing again and we’re on the lookout for a Full Stack Developer who loves building smart automations, seamless web tools, and pushing the boundaries of what AI can do to make work faster and smarter.

If JavaScript or Python feels like your second language, you thrive on automating manual chaos, and the idea of working with Notion, n8n, and AI agents gets you fired up — we want to hear from you!

Who We Are

Hello, hola, oi 👋 — we’re Optemization, the world’s first Notion consultancy from NY 🍎 We’re a fully remote, modern team with a flat hierarchy that values autonomy, transparency, and collaboration.

Our small but mighty team of 13 (and growing!) works with a diverse range of clients — from US tech startups and agencies to venture capital firms — to help them achieve operational excellence through innovative solutions.

In short: “We take our work seriously, but not ourselves.”

A Day In The Life

• Build internal tools, scripts, and web apps to automate workflows and speed up operations
• Create AI agents and tools to support data migration and workspace building
• Automate data migration from other platforms into Notion (like ClickUp, Confluence, etc.)
• Set up n8n workflows, Zapier-style integrations, and low-code automations
• Occasionally build things inside Notion itself when needed (don’t worry — we’ll train you if you’re new to it)
• Document your work clearly so teammates and clients don’t lose their minds
• Join a few Zoom calls with clients and the team each week

The Ideal Person For This Role

• 2–5 years of software development experience (mid to mid+ level)
• Strong in JavaScript (preferable) or Python
• Solid experience with web development (bonus for React / Next.js) and API integrations
• Familiarity with n8n, no/low-code platforms, and automations
• Passion for AI, automation, and using tools like Cursor, Cline, Roo-code, etc.
• Ability to work independently, take initiative, and ship clean code
• Comfortable working independently, as well as collaborating with a team
• Strong English communication skills (written and spoken) is a must
• The ability to take Zoom calls during North American business hours (Note: a high-speed internet connection is a must, along with a quiet, distraction-free work environment to take Zoom calls)

Big Plus If You Have

• Experience building or managing Notion workspaces
• Already built AI agents using both low/no-code tools (Flowise, Langflow, CrewAI, etc.) and full-code frameworks (Langchain, etc)
• Previously built internal tools or handled complex data migrations
• You love clean UX and thinking about how to make tools intuitive

Not Sure If You’re a Perfect Fit?

That’s okay — if you’re excited about the role and can show us your skills, we care more about mindset and curiosity than a perfect CV. We’ll support you in learning anything you’re not already fluent in (like Notion, n8n or AI Agents).
