Hire FinTech Software Developers

Why Companies Hire FinTech Software Developers in 2026

The demand for financial software developers who build new financial systems and modernize existing financial software stays high. The immediate task may be to create a digital wallet and payment gateway, provide a product engineering service for financial software platforms, or build a new SaaS product from scratch.

In 2026, the global FinTech market is estimated at $460.76 billion. According to Fortune Business Insights, this market will reach about $1.76 trillion by 2034, with a compound annual growth rate of 18.2% from 2026 to 2034.

New FinTech companies continue to enter this market, although the rate varies by year and region. The established providers of financial software answer this competition: they add new products, enter new regions and connect more third-party financial services.

This growth can also expose the limits of the software that financial services companies already use: 

• a new region adds its own technical and regulatory requirements to an established product. 
• the volume of transactions grows with the number of customers
• the financial workflows of the businesses that use this product become more complex.

The financial software that supported your business earlier may become slow under this load, while years of separate integrations and workarounds can leave it fragmented. Scaling an outdated or poorly designed system can cost more as the transaction volume and integration requirements grow. The company then needs to modernize their infrastructure or legacy banking system. When further patching costs more than rebuilding critical components, your company hires the financial app developers who rebuild them. 

Manual data entry can be one source of this cost. When your company's data is divided between disconnected spreadsheets and applications, reporting is slow, and your managers receive the financial figures later than they need them. This can create a need for Power BI developers experienced in the finance industry who build the reporting pipelines, dashboards and financial data models that the existing systems do not provide.

The underlying infrastructure can age. Сhanges to poorly documented legacy code can become more expensive and risky. When this platform does not support your new workflows, integration requirements or financial controls, your business needs cloud app developers experienced in finance to build the missing parts of the product and connect them to the existing infrastructure.

Some financial services companies also need self-service infrastructure. Their developers lose time waiting for environments, deployments and infrastructure changes, while releases depend on manual work. Financial software developers and platform engineers automate these processes and give the product staff repeatable ways to build, test and release financial software.

Depending on the product and the applicable regulations, software that processes payments or stores financial data may require:

• access controls that decide who inside your company sees a customer's balance
• audit trails that record every change
• encryption
• transaction monitoring
• regulatory reporting
• KYC and AML integrations
• other controls required by the product and the applicable regulations.

What exactly you need depends on your financial product, your market and the jurisdictions where you operate. A payments app in the UK and a consumer lending app in Germany have different lists of requirements. However, most of the time this type of work requires remote financial software developers experienced with financial data security requirements and, for regulated products, software engineering and software testing expertise for banks and financial institutions. 

North America accounted for more than 30% of the global FinTech market, and Asia Pacific accounted for a similar share. You may need financial software developers when you start selling to customers in several countries or expand into markets in Asia Pacific, Europe, South America or other regions.

The same product may then need to work with additional currencies and the payment methods that customers in these markets commonly use. This product may also need to apply tax rules based on the transaction type, the locations of the customer and the seller, and the applicable local regulations. This expansion can also introduce requirements related to legal entities, cross-border data transfers, local data residency and regional banking APIs.

Every jurisdiction you enter adds its own rules to the same product. Legal, compliance and product staff determine which rules apply to a customer and to a transaction. Financial software app developers implement these decisions in the code and maintain them after the applicable regulations change. This is why you hire financial software developers who have already worked with several jurisdictions.

The UK FinTech sector includes more than 4,400 active companies, and London is the main hub of this sector. Your customer in this market compares your product with several other products before the purchase.

They ask which banks and payment methods your product already connects to, how long the onboarding of their own users takes, which reports the product produces and in which format, how it stores and encrypts their financial data, and which regulatory requirements of your market it already covers. A product that already answers these questions has an advantage during vendor selection. This is why you hire financial software developers in the UK before you start selling in such a market.

Depending on the product, it may exchange data with banking APIs, payment gateways, accounting platforms, ERP and CRM systems, identity providers, fraud detection services and your internal reporting software. The work may be to build and scale solutions across multiple business finance platforms  or to integrate return protection claim functionality into a financial services mobile app.

When these connections are missing or unreliable, your employees may need to copy data between these systems by hand and correct the format of the files they transfer. Errors from this manual work accumulate, and the financial operations of your company take longer. This is why you also hire best financial app developers who can build and maintain these connections.

By 2026, AI has become another common reason to review financial software. In a McKinsey US C-suite survey, 92% of executives expected their companies to increase spending on AI. This creates demand for developers specializing in AI integration for finance and for AI engineers in financial services.

Some financial products use AI for document processing, reconciliation, fraud analysis, forecasting and customer support. The development work may include build and maintain data pipelines, implement ML models, integrate with your existing cloud infrastructure, or add retrieval-augmented generation pipelines without breaking the existing workflows.

These features can process your customers' financial data, which means that they also need strict data controls, validation, monitoring and auditability.

Financial services companies hire custom financial services developers for all of these reasons. These developers replace web, backend or app software that can no longer manage the load. In other cases, they rebuild only the parts that your business has outgrown or build the components that were not included in the product earlier.
