Financial Markets / Risk Technology Engineer

Investment Banking | Trading, Risk & Capital Markets Technology

The Mission

West Code is hiring experienced engineers for technology projects across investment banking, capital markets and risk. We are looking for people who combine strong software engineering with real understanding of financial-markets environments, where data quality, performance, resilience and business-domain context are critical.

Depending on the project, you may work on trading and execution platforms, pricing, market data, position and exposure services, risk engines, post-trade processing or regulatory technology.

What You’ll Work On

• backend services supporting trading, risk or capital-markets workflows

• real-time and event-driven systems

• market data, positions, exposures or pricing-related services

• high-throughput data processing and integration pipelines

• APIs and integrations across front-, middle- and back-office systems

• systems where correctness, resilience and auditability are essential

• technical design and architecture decisions with senior engineers and domain stakeholders

• production support and continuous improvement of business-critical platforms

Technology

We are particularly interested in engineers working with Java, Kotlin, Python or C++, depending on the project. Typical environments also include Kafka, SQL, distributed systems, cloud platforms, Kubernetes and modern observability tooling.

Must Have

• 5+ years of professional software engineering experience

• strong backend engineering skills in Java, Kotlin, Python and/or C++

• experience with distributed, event-driven or high-volume systems

• solid understanding of production reliability and failure handling

• good SQL and data-handling skills

• good English

• ability to work with both technical and business stakeholders

• commercial experience in investment banking, capital markets, asset management, hedge funds or financial risk technology

Strong Advantage

• equities, fixed income, FX, credit or derivatives

• market data or pricing systems

• trade lifecycle and post-trade processing

• market, counterparty or credit risk

• positions, P&L, exposure or limit systems

• low-latency or high-throughput architectures

• Kafka and event-driven architectures

• Kubernetes and AWS / Azure / GCP

• regulatory reporting or other regulated capital-markets systems

Working Model

• B2B cooperation

• remote or hybrid work depending on the project

• projects with banks, investment firms, asset managers and other financial institutions

• international teams and senior stakeholders

• English used on most projects

B2B Rate

180–240 PLN/h + VAT

Final rate depends on technology, seniority, financial-markets expertise and project scope.

Why West Code

West Code builds engineering teams around ownership and strong technical delivery, not just individual roles. We are developing a dedicated business unit focused on technology projects for banks, investment firms and other financial-services organisations.

These are projects where understanding the business domain can matter as much as knowing the technology. You’ll work in senior environments on systems tied directly to trading, risk and financial decision-making, with strong technical ownership rather than purely ticket-driven delivery.

If you have serious engineering experience in financial markets or risk technology, apply and let’s talk.
