About the role 🤓

We’re looking for a Software Engineer to join our Finance Platform team, where engineering plays a critical role in how seQura scales.

As the company grows across markets, products, and transaction volumes, financial operations become increasingly complex. The challenge isn’t simply processing more data — it’s building systems that allow Finance teams to operate efficiently without adding operational overhead.

You’ll help transform manual financial processes into scalable products, automation, and self-service capabilities. From enabling business teams to resolve operational issues independently to building robust integrations with critical financial systems, your work will directly influence how efficiently the company can grow.

This role combines software engineering, systems thinking, and problem-solving in a domain where reliability, accuracy, and operational excellence matter every day. You’ll work closely with Finance stakeholders, Product, and Engineering to turn operational complexity into scalable technology solutions.

About the Merchant Experience team 🧩

Team mission

To turn financial operations into scalable systems.

We build the platforms, automation, and tooling that allow Finance teams to operate efficiently as seQura grows, reducing manual work, increasing operational autonomy, and ensuring financial processes remain reliable at scale.

What we own

• Accounting processes and supporting systems across seQura

• Integration with NetSuite ERP

• Financial data flows and operational controls

• Custody-related processes and tooling

• Treasury and disbursement capabilities as the domain continues to expand

• Internal operational platforms and tooling that enable Finance teams to work efficiently and independently

How we work

• Team of experienced engineers supported by a Product Manager and a Tech Lead Manager

• Strong collaboration between Engineering and Finance stakeholders

• Engineers are expected to understand business processes, not just technical requirements

• High ownership environment where engineers contribute from problem discovery through delivery

• Agile development process based on Scrum methodologies

The team collaborates closely with Finance, Merchant Onboarding, Business Operations, and many other domains across the company, as financial processes are deeply connected to how seQura operates and scales.

What challenges you'll be solving 🚀

• Replace manual financial workflows with scalable automation that reduces operational complexity as the business grows

• Build self-service capabilities that allow Finance teams to solve operational issues independently without relying on engineering intervention

• Evolve our NetSuite integration towards a seamless financial platform where critical accounting data flows reliably across systems

• Investigate complex financial and operational issues where the challenge is often discovering the problem before solving it

• Design resilient systems that improve the reliability, accuracy, and traceability of accounting and treasury operations

• Help the organization scale transaction volumes and financial complexity without scaling operational burden at the same rate

• Partner closely with Finance stakeholders to understand business processes and translate them into sustainable technical solutions

• Contribute to the expansion of the team's domain as Treasury capabilities become an increasingly important part of the platform

What to expect in the next 90 days 🏁

Month 1: You’ll get familiar with seQura’s financial operations, accounting workflows, and supporting systems. You’ll ship a meaningful Finance Operations feature early on while building context around how the company manages financial data and operational processes.

Month 2: You’ll develop a solid understanding of how financial information flows across systems and be able to investigate and debug accounting-related issues with support from the team. At this stage, you’ll start identifying opportunities where automation or tooling can reduce operational effort.

Month 3: You’ll own a medium-sized initiative end-to-end, from design through delivery, collaborating with both technical and business stakeholders. You’ll be expected to make technical decisions, manage trade-offs, and deliver solutions that create measurable operational impact.

What we are looking for:

• 5+ years of experience as a Software Engineer
