What does a Sr Python Engineer do?

A Sr Python Engineer is an experienced software developer who specializes in designing, developing, and maintaining applications using the Python programming language. They often lead projects, mentor junior engineers, and work on complex problems that require deep technical expertise. Their responsibilities may include writing efficient code, optimizing performance, integrating with APIs or databases, and ensuring the overall quality of software solutions. Additionally, they may collaborate with cross-functional teams to deliver robust and scalable applications.

What are the key skills and qualifications needed to thrive as a Sr Python Engineer?

To thrive as a Sr Python Engineer, you need advanced proficiency in Python programming, strong knowledge of software design patterns, and experience with scalable application development, often supported by a degree in computer science or related field. Familiarity with frameworks like Django or Flask, version control systems such as Git, and cloud platforms like AWS or Azure is typically required, with certifications in cloud or Python development considered a plus. Excellent problem-solving abilities, strong communication, and leadership skills help you collaborate effectively and mentor junior engineers. These competencies are critical for delivering robust, efficient solutions and driving technical excellence within development teams.

What are some common challenges Sr Python Engineers face when working on large-scale applications?

Sr Python Engineers often encounter challenges related to maintaining code quality and scalability as applications grow. Managing dependencies, ensuring optimal performance, and coordinating with cross-functional teams can be complex, especially in distributed systems. Additionally, integrating new technologies or frameworks while maintaining backward compatibility requires careful planning and communication. Proactive code reviews, clear documentation, and collaborative problem-solving are essential to overcoming these challenges.

What is the difference between Sr Python Engineer vs Python Developer?

AspectSr Python EngineerPython Developer
Required CredentialsBachelor's degree in CS or related field, experience in Python, often some leadership skillsBachelor's degree in CS or related field, strong Python skills, often less emphasis on leadership
Work EnvironmentTeam lead, project architect, involved in system design and optimizationCode writing, feature development, bug fixing
Employer & Industry UsageTech companies, startups, enterprise softwareWeb development, data analysis, automation projects

While both roles require strong Python skills, Sr Python Engineers typically have more experience, leadership responsibilities, and involvement in system architecture, whereas Python Developers focus more on coding and feature implementation.

Senior Associate, AI Deployment and Production - Data & Technology Solutions

StepStone Group

La Jolla, CA • Hybrid

Full-time

Posted 18 days ago

Job description

Position Overview:

The Senior Associate, AI Deployment & Production will be a senior member of the Applied Engineering Solutions team within StepStone's DATS department. This person is an expert Python engineer who helps the AI research team write better code and brings their work to robust production. They own the productionization framework around AI solutions - a clean, well-designed package API, async orchestrators (Celery or equivalent), sensible REST endpoints, and the data models the solution requires - and review AI projects to raise code quality. The role also carries low-level language depth (C, C++, or Rust) used for optimization, including rewriting performance-critical paths and migrating business logic out of the firm's PHP systems into faster implementations. This role suits an engineer who is equally strong at software design, productionization, and performance work.

Essential Job Functions:

  • Review AI research projects and raise the quality of their Python code design (module/class/function structure, typing, testing, packaging)
  • Build out the production framework for AI solutions: a well-designed package/library API, async scalable orchestrators, coherent REST endpoints, and the data models the solution requires
  • Take research and prototype AI code to scalable, reliable production, owning quality and standards before release
  • Apply low-level language skills (C, C++, or Rust) to optimize performance-critical paths as needed
  • Lead optimization of the firm's PHP workloads: implement low-level alternatives where warranted, or re-architect so Python (or a low-level service) owns the business logic and PHP simply calls it
  • Partner with QA to define and meet testing and acceptance goals; build monitoring and validation around AI pipelines
  • Contribute to shared frameworks (private PyPI/polyrepo packaging) and DevOps (GitHub Actions, Helm-based deployment)
  • Mentor analysts and associates and act as a senior reviewer for AI and engineering work

Qualifications:

  • Bachelor's degree in Computer science, Engineering, a quantitative field, or equivalent practical experience
  • 6+ years of software/data engineering experience, including production ownership and demonstrable technical leadership or mentorship
  • Expert Python: idiomatic, well-structured code (modules/classes/functions), strong testing and packaging discipline, and hands-on experience taking research/prototype code to scalable production
  • Production experience with Celery (or comparable async/distributed task orchestration), Flask (or similar) services, and SQLAlchemy (or comparable ORM) data modeling
  • Working proficiency in at least one low-level language (C, C++, or Rust) for performance optimization
  • Demonstrated ability to lead code review and own quality for a team - not just individual deliverables
  • Strong communication skills; comfortable partnering with research teams and owning JIRA coordination

Other Knowledge, Skills and Abilities:

  • AI engineering experience: ETL and RAG pipelines, LLM API integration, document extraction
  • Experience profiling and optimizing performance-critical code, and interfacing low-level code with Python (e.g., bindings/extensions)
  • Familiarity with PHP
  • Familiarity with Kubernetes and GitHub Actions (or comparable CI/CD)
  • Familiarity with finance, private markets, or investment data domains

Salary Range: $140,000

The salary range is an estimate of pay for this position.  Actual pay may vary depending on job-related factors that can include location, education, skill, and experience.  The salary range does not include any benefits or other forms of possible compensation that may be available to employees.
