## Description

**CAPCO POLAND *We are looking for Poland based candidate. **

At **Capco Poland,** we’re not just another consultancy - we’re the spark behind digital transformation in the financial world. As a global leader in technology and management consulting, we thrive on helping clients tackle the toughest challenges across banking, payments, capital markets, wealth, and asset management.

**Role Overview**

 

We are looking for an experienced **Full-Stack Engineer** to join Capco on a project within investment banking. The ideal candidate brings strong **Python backend development** expertise, hands-on experience with **React and TypeScript**, and a solid understanding of scalable APIs and cloud technologies. Experience with **Generative AI, LLMs, RAG and AI agents** is also important. You'll build secure, production-ready applications, combining strong engineering practices with a proactive, collaborative approach to problem-solving.

**Key Responsibilities**

- Design, build, test and maintain secure, scalable backend services and APIs, primarily using Python.

- Deliver production-quality code through sound engineering practices: version control, automated testing, code review, CI/CD, and clear technical documentation.

- Integrate services with internal platforms, data sources and third-party APIs, handling authentication, authorisation, resilience, and error management appropriately.

- Build and support AI-enabled features, including integrations with LLMs, retrieval-augmented generation (RAG), prompt workflows, and agentic patterns.

- Implement appropriate AI evaluation, monitoring, guardrails, and human oversight to ensure solutions are reliable, secure, and used responsibly.

- Investigate and resolve defects, performance issues, and operational incidents; use logs, metrics, and traces to improve reliability.

- Work with product, design, data, and engineering colleagues to turn requirements into practical, maintainable technical solutions.

- Contribute to technical design discussions, estimate work realistically and deliver agreed outcomes to time and quality expectations.

- Keep up to date with relevant engineering, AI and security practices, applying them pragmatically to day-to-day delivery.

**Required skills:**

- Strong hands-on Python development experience, including building backend applications, services, and RESTful APIs.

- Experience with common Python frameworks and tooling, such as FastAPI, Flask or Django; pytest; dependency/package management; and asynchronous programming where relevant.

- Front-end development experience with React, TypeScript, JavaScript, and modern UI/component libraries.

- Experience building full-stack applications or collaborating closely with frontend engineers on API contracts and user journeys.

- Good understanding of software engineering fundamentals: clean code, object-oriented and/or functional design, testing, debugging, API design, and source control.

- Experience working with relational and/or NoSQL databases, writing efficient queries and designing data models.

- Practical experience building or integrating generative AI solutions using LLM APIs and orchestration frameworks.

- Understanding of RAG, embeddings, vector stores, prompt design, agent workflows, model evaluation, and AI safety/guardrails.

- Experience with cloud-hosted applications, containers, and CI/CD pipelines.

- Awareness of secure development practices, including secrets management, access control, data protection, and dependency security.

- Strong analytical and problem-solving skills, with the ability to work through ambiguous technical issues.

- Clear written and verbal communication, able to explain technical decisions to engineers and non-technical colleagues.

**Nice to have: **

- Familiarity with observability tooling, such as application logging, monitoring, and distributed tracing.

- Experience working in regulated, enterprise-scale or security-conscious environments.

**Recruitment Process:**

- HR Interview with the recruiter

- Technical Interview

- Client Interview 

- Feedback and offer
