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 up-to-date 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
