Job description

Ampliwork builds Enterprise-Grade AI Agents that amplify Human Potential to drive

business productivity and growth since 2017. Ampliwork’s AI Agents streamline complex

multi-step workflows in highly regulated industries such as Financial Services.
At Ampliwork, we build bespoke AI Agents and enterprise agentic workflows that solve complex business challenges. We are a fast-moving startup with engineering hubs in Montreal and India, dedicated to shipping production-ready AI solutions.

About the role

We are looking for a Senior Python Developer with strong core software engineering fundamentals and hands-on experience building production-grade, cloud-native systems.

This is a highly hands-on role for someone who can take end-to-end ownership of solutions — from architecture and development through deployment, testing, client interaction, and ongoing delivery.

While experience with Generative AI and agentic systems is important, we are primarily looking for a strong senior Python engineer who knows how to build reliable, scalable enterprise software.

This is an urgent hire with an immediate start date.

What you'll do

• End-to-End Ownership: Drive the full development lifecycle of custom AI agents and agentic workflows, taking complete accountability for project delivery beyond individual components.
• Cross-Functional Collaboration: Partner closely with Data Science, DevOps, Product, and Pre-Sales teams to architect and ship scalable solutions.
• Client Interfacing & Communication: Directly communicate with clients to set priorities, manage the book of work, and effectively address urgent technical queries.
• Cloud-Native Architecture: Build resilient, cloud-native microservices using modern Python frameworks, AWS infrastructure, and scalable database systems.
• Testing & Quality Assurance: Drive high standards through comprehensive testing suites (Unit, Regression, Integration, and Performance testing) within CI/CD pipelines.
• Multi-Project Execution: Comfortably balance, prioritize, and deliver on multiple client

What we're looking for

• Strong professional experience as a Python software engineer/developer , ideally at a senior level.
• Advanced hands-on proficiency with Python .
• Strong experience with FastAPI and Pydantic .
• Proven experience designing and delivering production-grade, cloud-native systems .
• Hands-on experience with AWS and cloud architecture.
• Experience working with PostgreSQL and NoSQL databases .
• Strong understanding of APIs, microservices, and API security.
• Strong knowledge of automated testing, including unit, integration, regression, and performance testing.
• Experience with CI/CD pipelines and modern software engineering practices.
• Practical experience with Generative AI architectures and/or agentic frameworks .
• Ability to independently own projects from technical design through production deployment.
• Strong problem-solving skills and the ability to work effectively across multiple concurrent priorities.
• Strong communication skills and comfort working directly with internal stakeholders and clients.
• A self-starter mindset with a strong sense of accountability and ownership.

Even better if you have

• Core Technical Stack: Strong hands-on expertise in Python , FastAPI , and Pydantic .
• GenAI Experience: Practical experience delivering solutions powered by Generative AI architectures and agentic frameworks.
• Cloud Infrastructure: Solid hands-on experience with AWS and cloud-native architecture principles.
• Databases: Proficiency with PostgreSQL and NoSQL database engines.
• Security & Testing: Strong knowledge of API security , automated testing frameworks ( Unit, Integration, Performance, Regression ), and CI/CD pipelines .
• Mindset & Leadership: High degree of self-initiative, strong client communication skills, and a proven track record of shipping end-to-end enterprise solutions.

Start Date: Immediate — Urgent Hire

Location:
Montreal, Canada: Hybrid — 2 days per week in the office
India: Fully Remote

Candidates must be based in either Montreal or India .
