About the role

We are looking for a Principal Forward Deployed Engineer (FDE) to lead complex system modernization initiatives, combining deep architecture and technical leadership expertise with modern AI-assisted engineering practices.

Responsibilities

  • Lead the technical direction of complex legacy system modernization initiatives, from initial assessment through transition and implementation.
  • Analyze existing applications, architectures, dependencies, databases, and business logic to build a comprehensive understanding of legacy environments.
  • Define and plan transition architectures and modernization strategies, including the progressive refactoring of legacy systems.
  • Guide the modernization of database components, including stored procedures and database-dependent application logic.
  • Use AI tooling to analyze existing codebases and generate high-quality technical documentation that supports modernization decisions and engineering execution.
  • Apply structured AI-driven development workflows, particularly reverse engineering, Spec-Driven Development (SDD), and test generation.
  • Translate an initial mission and scope into an actionable technical plan and continuously evolve it as new information and constraints emerge.
  • Take end-to-end ownership of technical delivery while providing direction and structure to the broader engineering team.
  • Remain actively involved in the engineering process, supporting architecture decisions, technical analysis, troubleshooting, and implementation when needed.
  • Communicate technical progress, risks, dependencies, and architectural decisions clearly to technical and client stakeholders.
  • Act as a trusted technical interface between client stakeholders and a fast-paced engineering team.

Qualifications

  • Experience working with system modernization projects in an architecture or technical leadership role.
  • Strong experience planning system transition architectures and defining modernization approaches for complex legacy environments.
  • Hands-on experience refactoring legacy systems, including systems involving database stored procedures.
  • Knowledge of legacy Microsoft IE5 HTCs and DHTML architectures.
  • Proven experience using AI tools to generate high-quality technical documentation from existing codebases under analysis.
  • Practical knowledge of structured AI-driven software development workflows, particularly reverse engineering, Spec-Driven Development (SDD), and automated test generation.
  • Demonstrated ability to take an initial mission and scope, own it end-to-end, and evolve it independently, both for yourself and the engineering team.
  • Strong architecture, technical leadership, analytical, and problem-solving capabilities.
  • Ability to operate effectively in complex environments with ambiguity and evolving requirements.
