Job description

Overview

We're looking for an experienced Senior Python Developer to join our team and help us evolve the core APIs that power our diverse set of customer and administrative applications. You'll be working on a large, established codebase that handles high-volume transactions for online ordering, mobile apps, and in-store kiosks. This is a highly impactful role for someone who is comfortable diving into complex systems and is a true SQL expert.

Responsibilities

• API Development & Integration: Design and build new REST API endpoints using Flask and the OpenAPI specification. You will also manage complex integrations with various external and internal third‑party APIs (e.g., payments, loyalty, other services)
• Performance Optimization: Proactively identify and resolve performance bottlenecks. You'll use tools like Datadog APM, advanced SQL query optimization, indexing, and caching (e.g., Redis) to ensure a low‑latency, high‑performance end‑user experience
• Database & Core Logic: Work directly with MySQL without an ORM, writing and optimizing complex, custom SQL queries to interact with a database featuring hundreds of tables
• System Modernization & Quality: Refactor and modernize parts of a large, 10‑year‑old codebase. You will also take ownership of expanding our automated test suite to ensure robustness and quality
• Problem Solving: Track down and resolve complex bugs across the application
• Feature Expansion: Build new backend functionalities that directly expand the feature set of our consumer‑facing products

Qualifications

• Experience: 5+ years of professional experience as a Python Developer
• Core Technology: Proven professional experience with Flask (strong preference) or Django
• Database Expertise: A deep, professional understanding of working directly with databases and writing complex, custom SQL queries; ORM experience is not a substitute
• Established Codebase Comfort: Significant experience working with and taking ownership of components within a large, established, and complex codebase (projects built from scratch only are not a fit for this role)
• High-Volume Application Experience: Experience working on a high-performance, consumer-facing application, ideally in e-commerce (restaurant or retail industry experience is a plus)
• Integration Experience: Prior experience integrating with key external systems like payments, CRM, loyalty, and marketing platforms
• Self-Starter & Communication: Excellent written and verbal communication skills. Must be a self-starter with the ability to work independently with minimal supervision
• Education: BSc in Computer Science, Engineering, or a relevant field, or equivalent experience
• Availability: Must be available to coordinate and be present in real-time until at least 5 p.m. US Eastern Time
