Role Overview

We’re hiring a Lead Python Developer to help us build, scale, and optimize a suite of modern, AI-powered, cloud-native applications. In this role, you'll not only architect and develop serverless backend systems on AWS but also help define development best practices, guide engineering standards, and mentor others across the team.

You’ll work closely with product, AI/ML engineers, DevOps, and front-end developers to bring new capabilities to life—particularly in the areas of automation, AI integrations, shared agent tools, and scalable APIs.

Key Responsibilities

• Design, build, and lead development of Python-based backend systems using AWS serverless services: Lambda, API Gateway, DynamoDB, Step Functions, SQS, and S3.
• Define and enforce clean, maintainable code standards, architecture patterns, and scalable API design.
• Act as a technical lead and mentor, reviewing code and coaching other developers on architecture, patterns, and quality.
• Collaborate with DevOps and infrastructure teams to support CI/CD pipelines (GitHub Actions) and IaC (Terraform).
• Integrate with external services and internal systems, including OpenAI, Google AI, and other LLM providers.
• Implement observability best practices using AWS-native tools (CloudWatch, X-Ray, etc.).
• Work cross-functionally to understand product goals and align technical solutions.
Help shape hiring decisions and technical evaluations for future team expansion.

• Proven success designing and implementing microservices and event-driven systems.
• Deep understanding of Python best practices (type hinting, modularization, error handling, dependency management, testing).
• Experience with auth mechanisms such as OAuth, JWT, Cognito, or IAM.
• Proficiency with GitHub, GitHub Actions, and collaboration workflows.
• Familiarity with Infrastructure-as-Code (Terraform preferred or AWS CDK).
• Excellent communication and leadership skills; ability to guide and influence team direction.
• Strong problem-solving skills and a mindset focused on performance, scalability, and resilience.

Preferred Qualifications

• AWS Certified Developer – Associate or similar certifications that demonstrate hands-on expertise with cloud-native AWS development.
• Python certification (e.g., PCEP, PCAP, PCPP1/2, or equivalent) that validates mastery of Python development standards and best practices.
• Experience working with LLMs or AI/ML frameworks such as OpenAI, Google AI, Hugging Face, or LangChain.
• Exposure to Retrieval-Augmented Generation (RAG) or AI-enhanced document processing and knowledge search architectures.
• Familiarity with real-time communication technologies, including WebSockets, GraphQL, gRPC, and REST APIs.
• Prior experience mentoring or leading development teams, including involvement in hiring, code reviews, and architectural decision-making.
