Senior Backend Engineer, Financial Automation

Bolt

Tallinn, Estonia

We are looking for a Senior Backend Engineer to join Bolt's Financial Automation team and build scalable systems that automate critical financial processes powering Bolt's global operations. You will have the opportunity to design and build the core platforms behind fiscalization (tax reporting), e-invoicing, and other financial flows.

If you are passionate about backend engineering and finance, and want your work to have a direct, measurable impact on a global business, this role will perfectly suit you.

About the role:

As a Senior Backend Engineer, you'll be a founding member of the team and the technical lead for a brand-new domain. You'll architect, build, and launch the backend platforms that power Bolt's financial automation - coding mainly in Node.js and TypeScript (don't worry, you don't need to know Node.js beforehand!).

You'll partner closely with Finance, Commerce, and Product stakeholders to translate complex regulatory and operational needs into scalable backend systems and APIs Bolt depends on. Product-oriented thinking is deeply ingrained in our engineering team's approach, so you'll have the chance to shape and lead initiatives end-to-end.

Main tasks and responsibilities:

• Architecting, designing, developing, and deploying the scalable and reliable core platforms for financial flows ensuring data completeness, consistency, quality and compliance in different regions.
• Building integrations with Bolt's existing backend services and various third-party tools and APIs.
• Setting the technical direction for the new domain and establishing engineering standards aligned with ITGC / DORA requirements.
• Providing technical leadership - mentoring engineers, driving system design reviews, and raising the bar for quality.
• Partnering with Finance, Commerce, and Product stakeholders to translate complex regulatory and operational needs into reliable automations.
• Helping lead features and initiatives from idea to positive execution.

About you:

• You have solid backend engineering experience and a track record of designing and shipping scalable, reliable systems.
• Experience in finance, fintech, payments, tax, or accounting domains is a strong advantage.
• You feel at home with microservice architecture and are experienced in API design.
• You possess a solid understanding of algorithms and data structures.
• You have empathy for stakeholders and end-users, and thrive in an environment with a fast feedback cycle.
• Previous technical leadership or tech-lead experience is a plus.
