  • Useful product with impact on customer’s business and lives

  • Want to help the average independent Joe (plumbers, painters, cleaners, photographers, freelancers…) become more successful?
  • Want to see your work in the hands of thousands of customers in a mater of days?

What we offer

  • Unmatched learning. Invoice Simple is extremely data oriented and few companies match our level of sophistication when it comes to experimentation, measurement and data analysis.
  • You’ll learn the skills to be able to systematically unlock the growth of any product.
  • We hope you’re excited to feel challenged every day here. As you develop mastery, we’ll make sure you’re constantly exposed to new opportunities to push yourself.

The role

  • The challenge for you to solve is maximizing the value customers get from Invoice Simple with your technical ingenuity.
  • In more concrete terms, this means improving percentage of people subscribing to Invoice Simple.
  • You’ll operate in an open-minded and autonomous environment; product improvements, customer communication and conversion optimization tests are all within your purview.

Your activities

  • Brainstorm ideas around increasing growth

About you

  • To enjoy this role, you’re probably inventive, curious, and comfortable digging into data. You have great technical ability and have deployed production code before.
  • You’re disciplined on working on the most impactful things. When looking to evaluate success, you turn to data and outcomes.
  • When things don’t work out, you take accountability. You thrive on feedback, take ownership for your work, and operate with a small ego. You don’t mind ambiguity and enjoy discovering solutions independently.
  • At the same time, you’re tenacious. You understand that big goals require persistence and hard work. You aren’t afraid to do some less-glamorous work in pursuit of a larger accomplishment.
  • You are not disheartened by short term set backs. You keep your eye on the ball and learn from what doesn’t work as well as what does.
  • You may or may not have experience as a ‘growth engineer’, but you frequently research and learn new things without someone else prompting you.
  • Picking up new technologies sounds enjoyable to you.
  • You are willing to challenge your own ideas and preconceptions with experiments and data.
