Engineering plays a very central part in the business.As a company with ambitions to be a world-class API solution for all things tax, we value quality over quantity when building. We also care about creating scalable, easy-to-operate, and maintainable software that our customers and daily users can rely on. Some pointers about our 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; architecture, tools, coding, testing, deployment, operations and scalingWe work in lean, small teams. We co-own the product roadmap with product managersWe choose collaboration, compassion, and trust over individualism and politicsWe prefer innovation, constant iteration and trust over competition and perfect solutions.We support each other, are kind by nature, and give as much feedback as possible to improve as professionals.We break 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 not satisfied with the status quo and push for change.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, learning with each step.We are comfortable making mistakes. We don’t blame and consider every failure an opportunity to improve.We measure everything, use the data to make decisions, and influence the organization We don’t allow blockers to prevent us from delivery.
