Its fun to work in a company where people truly BELIEVE in what theyre doing!

Job Description Summary:

Essential Duties and Responsibilities:

• Lead collaboration with product architecture and crossfunctional teams to translate complex business and enduser requirements into robust technical designs with a strong focus on language processing parsing frameworks and code analysis capabilities.

• Design architect and deliver largescale enterprisegrade software systems including parser engines compilerlike components and language analysis pipelines ensuring performance scalability accuracy and maintainability.

• Drive architectural discussions and technical direction for parsing and compileradjacent subsystems including grammar design AST construction semantic analysis and extensibility for multiple source languages (e.g. JCL COBOL SQL).

• Identify systemic code quality performance and architectural issues particularly within parsing pipelines and grammar-based systems and lead remediation through refactoring redesign or standardization.

• Produce highquality technical documentation including grammar specifications parser architecture designs and language-processing workflows; clearly communicate complex concepts to engineering and leadership stakeholders.

• Serve as an escalation point for complex debugging and production issues including parsing errors grammar ambiguities and language edge cases driving deep rootcause analysis and resolution.

• Operate with full autonomy to deliver complex enhancements such as new language support parser extensions or improvements to analysis accuracy and performance.

• Develop deep expertise in systemlevel integration including how parsing and metadata extraction integrate with downstream systems (e.g. data lineage analysis platforms or databases).

• Demonstrate technical leadership in collaborative engineering practices including reviewing parser implementations validating grammar changes and enforcing coding standards for language-processing components.

• Model a strong teamoriented culture while fostering domain expertise in compiler theory parsing strategies and language evolution across the team.

• Champion continuous learning and innovation in compiler techniques parsing algorithms and code analysis methodologies evaluating new tools and approaches.

• Exhibit strategic curiosity and an innovation mindset proposing new approaches to improve parsing accuracy performance extensibility and support for additional languages or dialects.

Required Qualifications:

• 8 years of professional software engineering experience with a proven record of delivering complex highimpact systems including language processing parsing or compilerlike systems.

• Demonstrated experience leading largescale initiatives involving parsing frameworks grammardriven systems or code analysis platforms.

• Expertlevel proficiency in C with deep understanding of objectoriented design memory management and performance optimization in parser or compileradjacent workloads.

• Strong understanding of compiler fundamentals including lexical analysis parsing techniques (LL/LR) AST design and semantic processing.

• Handson experience designing building or extending parsers interpreters or static analysis tools for structured or semistructured languages (e.g. JCL COBOL SQL or similar).

• Familiarity with parser/grammar tooling such as ANTLR yacc/bison JavaCC or equivalent including ability to design debug and evolve grammars.

• Strong understanding of REST APIs distributed systems and RDBMS concepts with SQL expertise across SQL Server Oracle and PostgreSQL.

• Extensive experience designing and developing enterprisegrade applications frameworks or platform components.

• Strong proficiency in Windows and Linux environments including debugging complex systemlevel and parser-related issues.

• Ability to mentor engineers and guide best practices in parsing design grammar management and language evolution.

• Strong communication skills capable of explaining complex parsing logic and compiler concepts to diverse audiences.

• Advanced expertise in Qt Core and lowlevel modules.

• Skilled at reducing platformspecific code and increasing portability across Windows and Linux.

• Strong command of OS internals filesystems threading models and debugging tools.

• Highly desirable: experience porting Windows applications to Linux.

• Exposure to IBM i (AS/400) and/or IBM z architectures desirable especially experience working with legacy language formats and mainframe source parsing.

AI & Developer Productivity Tools

• Hands-on experience using AI code assistants such as:
  GitHub Copilot Microsoft Copilot

• Ability to leverage AI tools for:
  Code generation Refactoring Unit test creation Documentation Development acceleration

• Strong understanding of validating and responsibly integrating AIgenerated code into complex parsing or compiler pipelines.

Containerization & DevOps

• Proficiency with Docker for:
  Image creation Multi-stage builds Debugging containerized applications Optimizing images for performance and footprint

• Experience containerizing parser engines batch analysis workloads or language-processing services.

Leadership & Senior-Level Responsibilities

• Defines system architecture and drives design decisions including parser frameworks and language-processing subsystems

• Mentors engineers and leads deep technical reviews particularly in grammar design parsing logic and performance optimization

• Drives complex root-cause analysis for production issues including language edge cases and parsing inaccuracies

• Partners with cross-functional teams to align product direction with language support and parsing strategy

• Owns long-term initiatives such as adding support for new programming languages or evolving parsing platforms

• Models engineering excellence in building reliable extensible and high-performance parsing systems
