Python Engineer

About the project:

We’re looking for a hands-on, self-sufficient Python Engineer to join a long-term product collaboration with an established European investment company. The company has been successfully managing multi-billion euro assets for 30+ years and is now actively investing in AI-driven innovation.

You'll work closely with a highly professional internal team — analysts, portfolio managers, and risk experts — to bring modern, impactful solutions into their everyday operations. The engagement spans several parallel sub-projects, so you'll be able to switch context and contribute across different workstreams within the same collaboration.

What You'll Be Working On:

• AI-powered internal platform already in production.

• Decision-making automation workflows.

• Work with financial data, reports, documents, and internal knowledge sources.

• Handling business-critical tasks that directly affect daily operations.

• End-to-end ownership: from architectural design to production deployment, including monitoring and production support.

Key Responsibilities:

• Design and implement scalable backend APIs using Python and AWS Lambda.

• Develop and manage OpenAPI specifications for all serverless APIs.

• Build and maintain data models and schema migrations using PostgreSQL on AWS RDS.

• Set up and maintain infrastructure-as-code using Terraform.

• Build and orchestrate workflows using AWS Step Functions.

• Collaborate with DevOps to establish smooth CI/CD pipelines using GitLab CI/CD.

• Use Amazon S3 for storing and serving assets and data.

• Monitor production systems and provide ongoing production support.

• Apply best practices in version control, testing, and security.

• Participate in code reviews, architectural planning, and agile team ceremonies.

Requirements:

• 3+ years of hands-on experience with Python 3.

• Experience building APIs using Flask or similar Python web frameworks.

• Experience developing serverless applications using AWS Lambda.

• Experience with AWS Step Functions for building and orchestrating workflows.

• Familiarity with API Gateway and/or ALB for routing and service integration.

• Solid understanding of PostgreSQL, with experience deploying to AWS RDS.

• Knowledge of Terraform for infrastructure provisioning and management.

• Familiarity with OpenAPI/Swagger for API contracts and documentation.

• Experience with GitLab and Git workflows for version control and CI/CD pipelines.

• Understanding of S3 use cases in web applications.

• Comfortable working in agile environments and taking initiative to solve problems.

Nice to Have:

• Experience with SFTP, SharePoint, or other enterprise integrations.

• Experience integrating with PowerPoint, Excel, or working with Power Queries.

• AI is used as part of the daily engineering routine — e.g., for troubleshooting and root-cause analysis — so hands-on experience with AI tools is a plus, and any background in AI integration is welcome, though not required.

• Knowledge of monitoring and logging tools within AWS.

• Previous experience in the fintech or asset management domain.

• Awareness of security practices for serverless apps (IAM roles, API authorization, secret management).

Stages of Interview:

• Interview with a Recruiter (45 minutes).

• Internal technical interview (1,5 hour).

• Interview with the client (1 hour).

What we offer:

• Long team focus: we create an environment of transparent communication, and minimal bureaucracy, which leads to long-term relationships.

• Development of niche expertise: we are working in several niches, such as FinTech, healthcare, and logistics. Therefore, our employees can develop their own expertise in these domains.

• Continuous learning: we create employee development plans / personal roadmaps /quick promotion processes.

• Internal career development: 80% of our current executives were promoted to those positions within S-PRO. We encourage initiative. If a person wants to set new challenges and grow, we will definitely support them.
  

Benefits and perks:

• Flexible schedule.

• Remote work model.

• Medical insurance.

• Paid vacations.

• Paid Sick-leaves.

• Paid State holidays.
