Devsu
Python Developer - Senior
About this role
We are looking for a Senior Application Engineer to design, develop, and support integration services, APIs, middleware, and automation capabilities that enable AI-powered business solutions. The role will focus on building scalable enterprise integrations, connectors, and services that allow AI agents and business applications to securely interact with internal and external systems. We are looking for an engineer who goes beyond simply implementing requirements: someone who understands the intended business outcome and the wider system context, identifies assumptions and trade-offs, and can determine when to proceed independently, seek clarification, or challenge a proposed approach. The ideal candidate combines strong Python software engineering experience with practical expertise in APIs, cloud-native applications, integration patterns, automation, and production systems.
Responsibilities
- Design, develop, test, deploy, and troubleshoot production REST APIs and integration services.
- Build and enhance MCP (Model Context Protocol) connectors and enterprise integration frameworks.
- Develop middleware services connecting AI platforms with enterprise applications and data sources.
- Create automation capabilities that streamline business processes and AI-assisted workflows.
- Collaborate with solution architects, product teams, and business stakeholders to define scalable technical solutions.
- Participate in code reviews, architecture discussions, and technical design sessions.
- Ensure solutions meet security, performance, reliability, scalability, and maintainability standards.
- Contribute to reusable frameworks, libraries, and integration patterns.
- Use AI-assisted development tools such as Codex in day-to-day engineering and review, test, and validate generated code.
- Diagnose and resolve production issues while considering both technical root causes and business impact. Requirements
- 5+ years of professional software engineering experience, with strong experience in Python.
- Proven experience designing and delivering production REST APIs.
- Strong understanding of API design principles, authentication, authorization, and enterprise integration patterns.
- Experience building and supporting cloud-native applications and services.
- Understanding of event-driven architectures and service-oriented architectures.
