Senior Python Engineer

Job Title: Senior Software Engineer

Location: Alpharetta

Employment Basis: Full Time

Company Overview: Solifi delivers a solid financial technology foundation for equipment, working capital, wholesale, and automotive finance firms. Our mission is to reshape finance technology by bringing together proven solutions into a singular powerful technology platform.

Role Overview: You will be working with other engineers to build out a new product for Solifi. The team consists of Python engineers, Angular engineers, and software quality automation engineers.

• Design, build and maintain Python backend services and RESTful APIs that power product features built on top of our data platform.
• Develop clean, well-structured application code in Python, focusing on readability, testability and long‑term maintainability.
• Design API contracts and service boundaries that balance product needs, performance and consumer ergonomics.
• Query and integrate with data lakes and data warehouses (e.g., S3‑based lakes, Redshift) to surface curated datasets through application APIs.
• Write and tune SQL against analytical and transactional sources to support product features and backend workflows.
• Build and maintain AWS‑native backend infrastructure using services such as Lambda, ECS/Fargate, API Gateway, S3 and RDS.
• Implement authentication, authorization, validation, error handling and observability across services.
• Partner with data engineers to understand upstream pipelines and ensure application services consume data correctly and efficiently.
• Work with product managers, designers and engineers to translate product requirements into well‑scoped services and endpoints.
• Troubleshoot and resolve issues across application, integration and storage layers, improving reliability and performance over time.
• Participate in code reviews, design discussions and planning sessions to ensure engineering excellence.
• Contribute to continuous improvement of backend patterns, tooling and developer workflows.

• Bachelor’s degree in Computer Science, Engineering or equivalent experience.
• 5+ years of experience in software engineering with strong exposure to cloud‑native backend services.
• Strong experience building production Python applications, including REST APIs and backend services.
• Proficiency with at least one modern Python web framework (e.g., FastAPI, Flask or Django).
• Hands‑on experience with AWS application services, especially compute (Lambda, ECS/Fargate or EC2), API Gateway, S3 and a relational database (RDS, Postgres or equivalent).
• Strong proficiency in SQL, including query design and performance tuning.
• Understanding of data pipelines, lakes and warehouses sufficient to consume them effectively from application code.
• Experience designing and versioning RESTful APIs and integrating with downstream consumers.
• Solid grasp of testing practices for backend services (unit, integration and contract tests).
• Strong understanding of service reliability, observability, logging and monitoring practices.
• Excellent problem‑solving, debugging and communication skills.
• Ability to work independently while collaborating effectively within a cross‑functional engineering team.

• Experience building services that sit on top of a data platform or data warehouse (e.g., Redshift, Snowflake, Databricks).
• Familiarity with columnar/structured data formats (Parquet, Avro, ORC) when consuming data from a lake.
• Familiarity with event‑driven architectures (SNS/SQS, Kafka, Kinesis).
• Experience with CI/CD workflows and modern deployment practices for backend services.
• Exposure to infrastructure‑as‑code (Terraform, Cloud Formation or CDK).
• Experience with containerization (Docker) and container orchestration.
• Familiarity with .NET (C#) services in a polyglot backend environment.
• Domain experience in risk management, analytics or financial platforms.
• Experience optimizing cloud compute and storage costs in AWS.

You bring strong expertise in Python application development, API design and building reliable backend services in AWS. You enjoy solving complex problems in product‑facing code, designing clean service boundaries and working closely with product, engineering and data teams to deliver features that are fast, observable and maintainable. You are comfortable working alongside a data platform—reading from data lakes and warehouses, writing efficient SQL, and understanding how data pipelines feed the systems you build on.

You operate independently on complex tasks while collaborating effectively with senior and staff‑level engineers on architectural decisions.
