Engineering Manager

Join to apply for the Engineering Manager role at Fonoa.

Overview

Engineering plays a very central part in the business. As a company with a world‑class API solution for all things tax, we prioritise quality over quantity in our development. We care about creating scalable, easy‑to‑operate, easy‑to‑expand, and easy‑to‑maintain software that our customers and daily users can rely on.

Engineering Culture
  • Engineers are given customer problems to solve rather than features to build.
  • We understand the customer's needs before considering implementation details.
  • Engineers are owners of their past, present, and future, encompassing architecture, tools, coding, testing, deployment, operations, and scaling.
  • We work in lean, small teams and co‑own the product roadmap with product managers.
  • We choose collaboration, compassion, and trust over individualism and politics.
  • We prefer innovation through constant iteration and trust over competition and perfect solutions.
  • We support one another, are naturally kind, and provide constructive feedback to continually improve as professionals.
  • We boil down complex problems and consistently seek the most straightforward solutions.
  • We take quality and security seriously and factor it into everything we do.
  • We are comfortable with change in terms of priorities, goals and deadlines. We see this more as an opportunity than a hurdle.
  • We are never satisfied with the status‑quo and push for improvements.
  • We seek those looking to make a severe impact and are excited about working in a high‑growth startup.
  • We ship fast, continuously, and iteratively multiple times per day, learning with each step.
  • We embrace mistakes as a conduit for learning. We don’t blame and consider every failure an opportunity to improve.
  • We measure everything, use the data to make decisions, and influence the direction.
  • We don’t allow blockers to prevent us from delivering. We step out of our comfort zone to find solutions and collaborate with other teams to advance initiatives.
  • We say things as they are, we don’t beat around the bush, we don’t waste time.
  • We ship.
Products

We have a suite of standalone API products that automate tax‑related workflows for any internet company:
Lookup, Tax, Returns, Data sharing and E‑Invoicing. We may discover new customer needs as we learn and develop new products as needed.

  • You focus on people; you can hire the right people, organise, 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’re a builder at heart, enjoy the opportunity of extensive exposure, and have an entrepreneurial attitude.
