Think self-service or freemium-led companies like Figma, Notion, Freshworks, and Slack. We do this by helping companies recognize signals across their - product engagement, sales, billing, and marketing data.

Founded in June 2021, Toplyne is backed by marquee investors and angels (we'll be happy to tell you how much we've raised, and from whom on call). We are building out our founding team as we speak and we'd love to chat with you!

You taking a lot of pride in writing scalable, readable & maintainable code. You have a product bent of mind. You like working in a fast paced environment and ship code most days of the week.

You don't mind getting on customer calls to understand their perspective to build a better product or help them with issues they might be facing.

You're hungry, ready to hustle, and keen to learn!

As a founding member of the core engineering team, you will:

• Develop massive, complex software systems that scale globally.
• Build and own a substantial part of the product and help build the culture of engineering within Toplyne

• Strong first principles

• Ability to collaborate with cross-functional teams to build and ship new features
• 2-6 years of experience
• Good understanding and experience working with javascript frameworks such as React.
• Work closely with developers and UX designers to ensure that the presentation layer is implemented in accordance with best above best practices and UX specifications.
