Senior Python Backend Software Engineer (10+ years coding, 5+ years Python) (Remote – India)

We are looking for a highly experienced Senior Python Backend Software Engineer with 10+ years of solid backend software development experience, at least 5 years of which should be in backend python services involving sophisticated scalable algorithms. Candidates should have hands-on experience building low-level frameworks such as: locking, session management, inventory management, invoicing, shopping, catalog, google index, server-side rendering, key-value store based transaction management, low-level chat implementation with key-value store. Experience working with ML experts to implement traditional ML algorithms at scale such as time series data processing, clustering, classification, and sophisticated metrics on data is a plus.

This role offers up to 2x local market rate, please do not apply if you do not meet the above criteria.

Key Responsibilities:

• Design, develop, and maintain scalable backend services using Python and Flask.
• Collaborate with front-end developers to deliver optimized endpoints suited for web and mobile clients.
• Architect scalable backend solutions leveraging AWS S3 or other key-value store system as a fundamental storage system replacing traditional relational or NoSQL databases.
• Implement and optimize low-level backend frameworks such as locking mechanisms, session management, inventory management, invoicing, shopping, catalog indexing, Google index processing, server-side rendering, key-value store-based transaction management, and low-level chat implementations.
• Troubleshoot and optimize cross-domain API requests, full-page caching, and CORS policies.
• Write efficient, modular, and maintainable object-oriented Python code.
• Develop and manage Ubuntu/Linux-based environments, including Bash scripting for DevOps automation.
• Collaborate with ML experts to implement traditional ML algorithms at scale, including time series data processing, clustering, classification, and sophisticated data metric computations.
• Design and optimize RESTful APIs ensuring high availability and performance.

Required Skills:

• At least 10 years of software development experience, with a minimum of 5+ years of dedicated Python backend development.
• Strong written and verbal communication skills in English to collaborate effectively in a remote, international team.
• Expertise in Python 3.x and Flask for backend development.
• Strong understanding of AWS services, including EC2, Lambda, S3, Cloud Front, and CloudWatch.
• Extensive experience designing and optimizing scalable algorithms for high-traffic backend systems.
• Strong experience working with key-value store systems for backend storage and transaction management.
• Expertise in object-oriented programming in Python.
• Experience working with Ubuntu/Linux environments and Bash scripting.
• Deep understanding of algorithms and system design, data structures, algorithmic optimization, and distributed computing patterns.
• Experience optimizing backend performance at scale such as shopping carts, catalogs, inventory management, and chat systems.

Preferred Qualifications:

• Experience designing and implementing low-level backend frameworks, including session management, locking mechanisms, and real-time chat using key-value stores.
• Experience collaborating with ML engineers to implement large-scale traditional ML algorithms, including time series analysis, clustering, and classification.
• Experience resolving cross-domain page serving issues at scale.
• Experience designing high-performance backend architecture and distributed storage solutions.
• Experience implementing large-scale indexing solutions, server-side rendering, and advanced caching strategies.
• Experience with DevOps practices and infrastructure automation.
• Experience working with ML experts to integrate backend systems with large-scale ML workflows, including time series analysis, clustering, classification, and advanced data metric computation.
• Strong problem-solving skills with the ability to optimize backend performance at scale.
