Job Summary:
We are seeking a Senior Full-Stack Software Engineer to own and deliver end-to-end software solutions for our Sales organization s AI-powered applications. You ll take ownership of the UI, workflow, integrations, and data layer across an existing portfolio of AI tools — driving architectural decisions, mentoring junior engineers, and collaborating with our AI team, Business Solutions Lead, and product owners — while our AI team continues to own the underlying algorithm and model components. You ll thrive in a fast-paced, Agile environment, take ownership from concept through production, and use AI-assisted development tools as part of your daily workflow.
What You Will Do :
Own the software layers of our AI-powered Sales applications — UI, workflow, integrations, and data validation — while our AI team owns the underlying algorithm and model components.
Take over support and enhancement of the existing AI application portfolio, progressively reducing dependence on the AI team.
Lead the design, implementation, and delivery of complex full-stack features, from user interfaces to services and data stores.
Architect scalable, robust solutions; participate in architecture reviews and POC reviews with the AI team, and contribute to the evolution of our software stack and solution designs for new tools.
Write high-quality, well-tested code with strong unit, integration, and end-to-end tests; champion quality, reliability, and maintainability.
Collaborate with the Business Solutions Lead, product owners, and cross-functional teams to refine requirements, define technical work, and prioritize enhancements.
Leverage the AI team s shared infrastructure, DevOps, and operational support rather than rebuilding it, deploying through the existing containerized platform and CI/CD pipeline.
Train other professionals and provide technical leadership on methods and processes within their discipline; mentor junior engineers and offshore support, and enforce best practices in code quality, documentation, testing, and version control.
What You Need to Succeed :
7 years of hands-on full-stack development experience (or equivalent), with a track record of delivering large-scale software from concept through production.
Bachelor s degree required (Informatics or Computer Science preferred).
Advanced proficiency in Python and React (JavaScript/TypeScript); experience building APIs with FastAPI or similar frameworks.
Deep experience designing, developing, and maintaining REST APIs and RESTful services, including event- and workflow-driven integrations (e.g., inbox and CRM connections); solid understanding of microservices patterns.
Working familiarity with DevOps and QE (quality engineering) concepts — CI/CD, containerized deployment, and automated testing — and comfort building cloud-based production systems (Azure primarily) within an existing shared platform.
Experience with SQL, data modeling, and designing for performance and reliability.
Fluent daily use of AI-assisted development tools, including agentic workflows and CLI s such Claude Code or Codex
Strong problem-solving, communication, and collaboration skills; ability to work effectively with both technical and non-technical stakeholders across cross-functional teams.
Demonstrated ability to lead initiatives, mentor others, and drive results in a fast-paced environment.
Preferred Experiences:
Experience integrating with or extending generative AI / ML services and agentic architectures.
Experience with prompt engineering and developing or maintaining reusable AI skills, prompt libraries, or tool definitions for agentic systems.
Dynamics 365 / CRM integration experience.
Experience with testing automation, release management, and support/on-call practices.
Background in sales or quoting workflows.
Must be able to clearly and concisely communicate technical perspective and status to ensure shared understanding both upwards and downwards in the organization.
Experience working in a fast-paced, agile environment while providing consistent application lifecycle management.
