Who are we looking for

There is no single perfect career path for this position. You may currently be working in Open Banking, payments, fintech, digital banking, merchant solutions, acquiring, payment platforms, e-commerce payments, embedded finance or e-invoicing. Your current title might be Product Manager, Product Owner, Partnership Manager, Business Development Manager, Payments Manager – or something entirely different.

What matters is that you understand how digital financial services work across organisational boundaries and bring experience from at least a couple of these areas: Open Banking/ payments, product development, and partnerships/ business development.

You are likely to bring:

• relevant experience in banking, payments, fintech, Open Banking, e-invoicing or another API- and partnership-driven environment;

• experience in product ownership, partnerships, business development, or ecosystem management;

• practical understanding of APIs, integrations, and collaboration between business and technology teams;

• experience working with B2B customers, merchants, platforms, or external partners;

• ability to turn opportunities into commercial propositions, business cases, roadmaps, and actionable plans;

• sufficient understanding of regulated financial services to work effectively with legal, compliance, risk, and security specialists;

• strong professional English.

A strong payments or fintech background combined with curiosity, commercial thinking and the ability to understand the wider value chain can be equally relevant.

What kind of person will succeed

• You enjoy building rather than simply maintaining.

• You see commercial potential and take initiative to pursue it. You can discuss an integration with a technology team, negotiate with an external partner and then bring several internal stakeholders around the same table to make things happen.

• You combine strategic perspective with hands-on attitude. When there is no established playbook, you are comfortable creating one.

Why join Bigbank

Rather than inheriting a narrowly defined product, you will be able to shape the strategy, operating model, partner network, and commercial direction of Open Banking and e-invoicing at Bigbank.

You can expect:

• genuine end-to-end ownership of two developing business ecosystems;

• the opportunity to build and grow rather than simply maintain;

• international scope across Bigbank’s markets;

• close collaboration with business, technology and control functions;

• direct access to decision-makers;

• considerable independence in shaping how the area develops;

• the possibility for the scope – and potentially the team around it – to grow as the business develops.

The role reports to the Head of Daily Banking Area and is based in Tallinn, Estonia. Initially, there are no direct reports – you will achieve results by bringing together expertise and resources from across Bigbank.

Bigbank offers a monthly gross salary of €4,500–€5,000 together with the full range of Bigbank Group benefits and, above all, the opportunity to shape and grow an area you can truly make your own.
