Job Description

Engineering plays a 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 in our development and care about creating scalable, maintainable software that our customers and daily users can rely on.

This role is focused on building and operating integrations with enterprise systems.

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 scaling

  • We work in lean, small teams. We co-own the product roadmap with product managers

  • We choose collaboration, compassion and trust over individualism and politics

  • We prefer innovation, constant iteration and trust over competition and perfect solutions.

  • We support each other, are kind by nature, and give as much feedback to improve as professionals.

  • We break down complex problems and consistently seek to find the most straightforward solutions.

  • We take quality seriously and factor it into everything we do.

  • We are comfortable with change, whether in priorities, goals, or 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 each step.

  • We are data-informed. And are ok with finding the data when it’s missing.

Our products

We have a suite of API products that automate tax-related workflows for any internet company. Those products are Lookup, Tax, Returns, Data sharing and E-Invoicing.

We may discover novel customer needs as we learn and spin up new products as required.

Our API docs

For you as an engineer, API documentation is probably an important part when considering a new career move. Thanks to the API docs, you can recognise how API works and how it is structured.

Please, visit our API documentation and learn more about our API endpoints and how to use them - https://docs.fonoa.com/.

“As an engineer, I follow a product through its lifecycle, from ideation to delivery and support, which gives a lot of exposure to the technology and customer needs. This allows me to learn to improve both myself and the product constantly.” - Philip Beel, Engineering Manager.

What you will do

  • Learn about how painful it is for companies to handle tax manually, and think about how our products are changing the status quo

  • Design, build, and operate scalable connectors between Fonoa and enterprise systems such as ERPs and billing platforms.

  • Own what you build, with the ability to decide how to make it and the responsibility of operating it in the production environment.

  • Work deeply with enterprise APIs and data models, building integrations that fit seamlessly into business processes such as Order-to-Cash and Procure-to-Pay.

  • Build high-throughput, fault-tolerant integration services that handle retries, idempotency, data consistency, and versioning across systems.

  • Collaborate closely with the product team to deeply understand Fonoa’s products, provide feedback from real-world integrations, and proactively suggest improvements where needed.

  • Work with customer teams to understand their ERP processes and constraints, ensuring Fonoa’s solutions fit seamlessly into existing workflows.

  • Record and collate lots and lots of data sets from all these operations for long-term storage and future insight

  • Use every learning and observation to improve our products, constantly

  • Understand customer needs and the pain points they experience with tax automation, particularly how tax fits into existing enterprise workflows.

  • Understand competitive products

You would be a great fit if

  • You are fully proficient in English. Written and spoken, we are from around the world, but we work in English.

  • You have a strong sense of ownership, care about what you build, and do the right thing that serves your customers.

  • You’re a builder at heart; you like the opportunity of having tons of exposure, making things work for a company long term, and having an entrepreneurial attitude toward anything that comes your way.

    • You have experience building or operating integrations with enterprise systems, such as ERPs, billing platforms, or large financial systems.

    • You understand how enterprise business processes like Order-to-Cash and Procure-to-Pay work, and how systems integrate within those flows.

    • You have hands-on experience with a single ERP or enterprise system and are motivated to apply those patterns while learning others.

    • You are comfortable working with complex external APIs and data models, and designing for reliability, scalability, and correctness.

  • You ship fast, continuously, and iteratively, learning each step.

  • You like to use data over opinions to make decisions. And are ok with finding the data yourself when it’s missing.

  • You are comfortable with change, either in priorities, goals and deadlines. You see this more as an opportunity than a hurdle. You are also satisfied with challenging the status quo and pushing for change.

  • You want to make a severe impact and are excited about working in a high-growth startup.
