Mid Level Back End Developer information

What is a mid level back end developer?

Mid Level Back End Developers are software professionals who specialize in server-side development, typically with 2-5 years of experience. They design, build, and maintain the logic, databases, and APIs that power web and mobile applications. Unlike entry-level developers, they are expected to work independently on complex features, contribute to architectural decisions, and collaborate closely with front end developers. Their work ensures that applications are scalable, secure, and efficient, making them an essential part of any software development team.

What are the typical responsibilities and collaboration points for a mid level back end developer within a software development team?

As a Mid Level Back End Developer, your daily responsibilities often include designing, implementing, and maintaining server-side logic, APIs, and database schemas. You will regularly collaborate with front-end developers to ensure seamless data exchange and with DevOps engineers to optimize deployment pipelines. Mid level roles also involve code reviews, troubleshooting, and contributing to architectural decisions. This position provides opportunities to mentor junior developers and work closely with product managers to translate business requirements into technical solutions.

What are the key skills and qualifications needed to thrive as a mid level back end developer, and why are they important?

To thrive as a Mid Level Back End Developer, you need proficiency in server-side languages (such as Java, Python, or Node.js), database management, and a solid understanding of API design and data structures, usually supported by a relevant degree or equivalent experience. Familiarity with frameworks (like Spring Boot or Express), version control systems (such as Git), and containerization tools (like Docker) is typically expected. Strong problem-solving abilities, communication skills, and the ability to collaborate effectively with cross-functional teams make you stand out in this role. These skills ensure robust, scalable backend systems and efficient teamwork, both of which are vital for delivering high-quality software products.

Software Guidance & Assistance, Inc. (SGA) is searching for a mid-level Back-End Developer (Python/API) for a Permanent FTE assignment with one of our premier AI and Financial Technology clients. Must be local to NYC or Miami
The successful candidate will join a small, highly collaborative engineering team responsible for designing and building a cloud-native Portfolio Management System for a hedge fund from the ground up. This is a dedicated role supporting a single client, working directly with the client's engineering leads while collaborating with the firm's engineering team through code reviews and shared development practices. The immediate focus is Bloomberg connectivity and the Python back-end that market data flows through.
This role is ideal for a hands-on engineer who enjoys startup environments, greenfield development, and solving complex backend engineering challenges involving APIs, real-time market data, and scalable cloud architectures. The initial MVP is targeted for delivery by year-end.
This is neither a junior nor senior/principal level role.
Responsibilities
  • Design, develop, and maintain backend services using Python and FastAPI.
  • Build scalable REST APIs supporting cloud-native financial applications.
  • Develop backend services and APIs from the ground up for a greenfield Portfolio Management System.
  • Integrate with Bloomberg and other third-party market data providers to support real-time market data ingestion.
  • Develop real-time backend services utilizing WebSockets and event-driven architectures.
  • Design scalable backend solutions capable of supporting high-volume market data and growing user populations.
  • Implement API throttling, rate limiting, caching, retry logic, and fault-tolerant data ingestion.
  • Design, develop, and optimize PostgreSQL databases and SQL data models; work with Snowflake as the cloud data warehouse where applicable.
  • Optimize application performance, cloud resource utilization, and overall system scalability.
  • Deploy and support applications within Microsoft Azure.
  • Collaborate daily with the client's engineering leads during U.S. East Coast business hours to design, troubleshoot, and deliver new functionality.
  • Coordinate with the firm's engineering team through code reviews, merge requests, and shared development standards.
  • Participate in architecture discussions and contribute to the overall technical direction of the platform.
  • Troubleshoot production issues and continuously improve application reliability, scalability, and performance.

Required Skills
  • 5+ years of backend software development experience.
  • Strong Python programming skills.
  • Experience developing REST APIs using FastAPI or similar Python frameworks.
  • Hands-on Bloomberg API integration experience.
  • Strong understanding of backend application architecture and distributed systems.
  • Experience integrating external APIs.
  • Strong SQL and PostgreSQL experience.
  • Experience designing real-time applications utilizing WebSockets, streaming technologies, or event-driven architectures.
  • Experience implementing API throttling, caching, rate limiting, retry logic, and performance optimization.
  • Cloud development experience utilizing Microsoft Azure, AWS, or Google Cloud Platform.
  • Experience using Git and modern CI/CD practices.
  • Ability to consistently work U.S. East Coast business hours while collaborating live with engineering teams.
  • Excellent analytical, troubleshooting, and communication skills.
  • Ability to work independently within a collaborative, fast-paced startup environment.
  • Bachelor's degree in Computer Science or related technical discipline (or equivalent experience).

Preferred Skills
  • Experience with Snowflake cloud data warehouse.
  • Experience with OpenBB, DataBento, Polygon, DXFeed, Yahoo Finance, or similar financial market data providers.
  • Capital Markets, Trading Systems, Hedge Fund, or Financial Services experience.
  • JavaScript development experience.
  • Docker and containerization.
  • SQLAlchemy or comparable ORM frameworks.
  • Experience building AI-enabled or LLM-powered applications.
  • Startup or early-stage company experience.
  • Experience designing highly scalable, low-latency distributed systems.
  • Experience participating in collaborative code review and peer development environments.
