Senior Software Engineer / Solutions Architect (Python & GenAI)

Provectus is an AWS Premier Consulting Partner and AI consultancy featured in Forrester's AI Technical Services Landscape, with 15+ years of experience and 400+ engineers. We build production AI for global enterprises in partnership with Anthropic, Cohere, and AWS.

We are looking for a Senior Software Engineer or Solutions Architect with deep Python and Generative AI experience. Someone who ships Python services, RAG systems, tools, and agents daily, with AI embedded across their entire workflow.

You might be an experienced SA ready to hit the ground running, or a Senior Engineer and Tech Lead ready to step into that role. Either way, you will own the technical vision, lead discovery, drive architecture decisions, and become the authority clients and teams rely on.

What You’ll Do:

• Write clean, production-grade Python across AI integrations, backend services, and RESTful APIs
• Implement and optimize RAG systems for production use cases
• Design and build LLM-based and agentic AI solutions that address real client business challenges
• Own the technical direction of client engagements from discovery through delivery
• Support presales: discovery calls, technical proposals, scoping, and client-facing demos
• Lead architecture reviews, produce technical design documents, and contribute to standards across the Python practice
• Mentor engineers, lead code reviews, and share knowledge across the team
• Build and maintain strong relationships with key client stakeholders as a trusted technical advisor
  

What You’ll Bring:
Mindset

• Full-stack mindset, comfortable across AI, backend development, and cloud infrastructure
• Already using AI tools in your daily workflow (Claude Code, Copilot, or similar)
• Proactive and self-directed; you own outcomes end-to-end and spot problems before they're handed to you
• B2+ English, comfortable collaborating across distributed, multicultural teams
  

Presales & Client Engagement

• Owns the client technical relationship; leading discovery, decomposing ambiguous requirements into technical components, presenting architecture, and pushing back on scope when it doesn't match timeline or budget
• Produces scoped, phased delivery plans with clear deliverables, dependencies, and risks
• Experience with cost estimation and cloud architecture cost optimization
  

Python, AI & Cloud

• 7+ years building and running production systems not only demos and POCs
• Strong understanding of AI/ML concepts and experience integrating AI/ML components into solutions
• Strong Python proficiency: OOP, design patterns, clean architecture, and performance optimization
• Experience building RESTful APIs with FastAPI, Django REST, or Flask
• Experience making and defending architectural trade-off decisions: microservices vs monolith, sync vs event-driven, SQL vs NoSQL
• Strong testing practices: pytest, mocking, and integration tests for AI systems
• Experience with Docker and Kubernetes
• Hands-on experience building production LLM-based applications and agentic workflows
• Experience with LLM APIs (OpenAI, Anthropic, or AWS Bedrock)
• Experience building and optimizing RAG systems
• Understanding of LLM evaluation techniques and quality assurance approaches
• Experience deploying and maintaining AI/ML models in production environments
• Hands-on experience with AWS (SageMaker, Bedrock, Lambda, ECS, S3, SQS, ECR, or similar); GCP considered
• Experience with React/Vue
• AWS and Claude Code Certifications
