Requirements
  • You are fully proficient in English, written and spoken.
  • You optimise for distributed and asynchronous work, favouring documenting and taking notes over ad-hoc face-to-face meetings that leave no trace and exclude the people who were not around at the right time.
  • You have a strong sense of ownership, you care about what you build, and you are building the right thing that serves your customers.
  • You focus on people; you are able to hire the right people, distribute and organise, are able to develop your team through constant feedback, keep them healthy and focus on retention.
  • You like to optimise processes to speed up product development without sacrificing quality.
  • You are a builder at heart. You enjoy the opportunity to have extensive exposure, making things work for a company in the long term, and having an entrepreneurial attitude towards anything that comes your way.
  • You are either eager to learn or comfortable scaling and operating large-scale microservices in high-load and growth environments.
  • You are knowledgeable in several languages. Most of our current codebase is in Go and TypeScript.
  • You enjoy removing unused features more than shipping new things that no one cares about. You run away from the success theatre.
  • You ship small things fast, continuously, and iteratively, learning on each step.
  • You like to use data over opinions to make decisions. And are okay with finding the data yourself when it’s missing.
  • You are comfortable with change, whether it involves adjusting priorities, setting new goals, or meeting deadlines. You see this more as an opportunity than a hurdle. You are also comfortable with challenging the status quo and pushing for change.
  • You’re looking to make a serious impact and are excited about working in a high-growth startup.
Responsibilities
  • Learn about how painful it is for companies to manually handle the tax lifecycle, and think about how our systems change the status quo.
  • Run a product engineering team, aligning business objectives with technical delivery.
  • Partnering with the Product Manager, co-owning the product roadmap
  • Guiding on day-to-day tactical work, hiring, onboarding, developing and mentoring. Your success is your team’s success.
  • Contribute to the broader engineering culture and goals by collaborating on high-level strategy with other Engineering Managers and our CTO.
  • Continuously strive to build the best API product, leveraging the best experience and capabilities.
