Our commitment to respect, transparency, and simplicity means you can trust us to always choose to do the right thing.

As a trusted partner for purpose-built AI and intelligent automation, we solve highly complex problems for our enterprise customers and put their information to work to transform the way they do business. Over 10,000 customers trust ABBYY, including many Fortune 500 ones. You will work on further developing a portfolio already containing client names such as DHL, Johnson & Johnson, FDA, DMV, PwC, KeyBank, Spotify, and H&R BLOCK.

We’re looking for an experienced QA Engineer to play a key role in shaping the quality strategy for ABBYY FineReader Engine, our C++-based SDK for OCR and PDF processing. You’ll work closely with other engineers to define and implement effective quality practices that support the development of high-performance, cross-platform libraries.

This is a hands-on role for someone who understands how to test complex, low-level systems and has a strong background in C++. You’ll help build and scale our automation efforts, improve how we detect regressions, and make sure our core libraries perform as expected across all supported platforms.

Responsibilities

  • You will contribute to the long-term quality approach for a complex C++ codebase, with a focus on performance, correctness, and platform compatibility.
  • You’ll help define and grow automated test systems for SDK-level testing across Windows and Linux.
  • You’ll be responsible for setting up and maintaining performance regression tracking, using tools like valgrind, perf, or custom benchmarks to monitor behavior over time.
  • You’ll work directly with logs, memory dumps, and tools like strace, gdb, and AddressSanitizer to track down hard-to-reproduce issues.
  • You’ll collaborate with developers and release managers to build quality into the development process from the start.
  • You’ll drive efforts to increase automated coverage for critical library APIs and workflows.
  • You’ll document test scenarios, triage results, and help define useful QA metrics.

Required Qualifications

  • 10+ years of experience in QA, including solid experience testing C++ applications or libraries
  • Strong understanding of C++, especially in the context of debugging, memory management, and performance profiling
  • Experience with tools like valgrind, strace, gdb, perf, or similar
  • Familiarity with cross-platform development and testing (Windows, Linux)
  • Ability to read and understand complex C++ code and spot issues early
  • Comfortable working in CI environments with build tools like CMake, Make, or similar
  • Strong written and verbal communication skills

Desired Qualifications

  • Experience testing SDKs, libraries, or developer-facing APIs
  • Exposure to fuzzing, static analysis, and similar testing methods
  • Familiarity with OCR, image processing, or document processing libraries
  • Experience working with hardware-agnostic test environments (e.g., virtualization, containers)
  • Curiosity to dig deep into low-level issues and propose practical solutions

Here are some of our local benefits:

  • Work from home, remotely, or hybrid
  • Partial compensation for glasses and lenses
  • Private health insurance
  • Volunteering Time Off (2 days/ year)
