We are hiring a principal-level engineer to diagnose structural flaws in existing software architecture, design systems that guarantee long-term stability and quality, and lead the engineering organization. 1.

Principal Software

Architect [Key Responsibilities] ~1.

Software Design Defect

Analysis & Resolution ~ Identify architectural anti-patterns in existing codebases and perform root-cause analysis ~ Trace root causes of hard-to-reproduce defects such as performance degradation, memory leaks, and concurrency bugs (race conditions, deadlocks) ~ Quantify technical debt in legacy systems and build a risk-prioritized improvement roadmap ~ Propose actionable redesign solutions — including backward-compatibility and migration strategy — rather than purely theoretical proposals ~2. Design & Management of Software Stability Assurance Systems ~ Develop in-house static-analysis diagnostic rules and integrate them into the CI pipeline ~ Design tiered severity quality gates and enforce them in the build process ~ Design suppression/waiver governance policy — format validation, deadline management, and automatic severity escalation upon deadline expiration ~ Establish system-level quality standards for memory safety, exception-handling consistency, and resource-disposal patterns ~ Establish post-mortem processes based on log/dump analysis following incidents ~3.

Technical Problem

Analysis, Design & Management ~ Break down cross-team technical challenges, define design direction, and manage assigned engineers' progress ~ Operate code/design review processes and give final approval on technical decisions ~ Maintain technical documentation systems such as Architecture Decision Records (ADRs) ~ Report technical risks and progress status to executives and other departments [Required Qualification] Education Bachelor's degree (BS) or higher in Computer Science, Software Engineering, or a related field - required Master's degree (MS), Ph.D. — preferred Experience ~15+ years of hands-on software development experience,



including 5+ years in an architecture/technical-lead role ~3+ years managing an engineering team (team size of 5 or more) ~ Experience leading technical evaluation C#: Expert-level with .NET (Framework/Core/5+), asynchronous programming (async/await, Task), LINQ, and memory management (including GC tuning) C++: Hands-on experience with contemporary C++ (11 and later), RAII, smart pointers, and template metaprogramming Interoperability experience between the two languages (P/Invoke, C++/CLI, etc.) — preferred System-Level Understanding File I/O: File-system structure, buffering/caching strategies, performance characteristics of large-file processing, file locking and concurrent-access control Database (covering RDB / NoSQL / File-based DB): Understanding of internal behavior, consistency models, and integration with query engines OS: Process/thread models, memory management, kernel/user-mode transitions, and platform differences between Windows and Linux Quality & Design Competency Experience developing or customizing static-analysis tools Deep understanding and practical application of design and architecture patterns (Layered, Hexagonal, Event-Driven, etc.) Experience designing CI/CD pipelines and building quality gates Experience automating test design/structuring — distinct from test-execution automation — including identifying test targets, generating test scaffolding, and managing coverage Experience identifying technical debt through code review and formulating refactoring strategy Communication Business-level English (capable of documentation, video conference, and technical discussion) Ability to explain technical content to non-technical stakeholders [Preferred Qualification] Domain experience in industrial automation, Manufacturing Execution Systems (MES), semiconductor/electronics equipment, or robotics Experience leading gradual migration/modernization projects for large-scale legacy system Experience using and driving team adoption of AI coding assitants (Claude Code, GitHub, Gopiolt, etc) Contributions to open-source static-analystis tools, or experience distributing internally developed tooling Experience working with multinational teams
