Staff Software Engineer - C++

Title: Staff Software Engineer - C++ Location: Poland, Warsaw (Hybrid)

About the role:

ABBYY Vantage is our flagship Document AI platform – a cloud-native, microservices-based product that combines purpose-built AI, OCR, NLP, and direct LLM integration to help enterprise customers extract, classify, and act on data from any document. Vantage 3.0, our latest release, introduces native Azure OpenAI integration, enterprise-grade compliance and redaction, a real-time analytics dashboard, and a growing library of pre-configured AI skills. Over 10,000 customers trust ABBYY – including Fortune 500 companies like DHL, Johnson & Johnson, FDA, PwC, KeyBank, Spotify, and H&R Block – to automate their most complex document workflows.

We are looking for a Staff Software Engineer to serve as a senior technical leader on the Vantage platform. You will drive the design and delivery of complex, cross-cutting capabilities – spanning document AI pipelines, LLM integrations, compliance infrastructure, analytics, and platform extensibility. Beyond your own code, you will act as a technical multiplier: influencing architectural decisions, setting quality standards, and developing the engineers around you. This is a role for someone who leads through depth, judgment, and impact.

Job Responsibilities:

• Technical Leadership: Drive the technical design and delivery of significant Vantage platform capabilities, from architecture and API contracts through deployment, monitoring, and iteration.
• Quality & Standards: Define and uphold engineering standards for the Vantage codebase – covering code quality, service reliability, performance, security, and compliance – and drive their adoption across teams.
• Strategic Collaboration: Act as a senior technical voice in cross-functional planning with product management, ML engineering, cloud architecture, and engineering leadership; translate business priorities into actionable technical roadmaps.
• Platform Improvement: Lead initiatives to improve Vantage platform health at scale: service decomposition, observability, CI/CD maturity, and developer productivity.
• Operational Excellence: Own high-severity incident response for Vantage cloud services; drive post-mortems and systemic reliability improvements.
• Engineering Mentorship: Mentor Senior and Principal Engineers on the Vantage team; build a culture of technical rigor, shared ownership, and continuous learning.
• Technical Innovation: Evaluate and champion adoption of new technologies – from GenAI model integrations to cloud-native tooling – that strengthen ABBYY's Document AI differentiation.

Job Requirements:

• More than 8 years of professional software engineering experience with deep expertise in C++

• Demonstrated ability to work with multiple programming languages, and willingness to work with both C# .NET and C++

• Strong command of microservices architecture, distributed system design, and cloud-native patterns at enterprise scale

• Experience in cloud and Kubernetes, preferably using Microsoft Azure (AKS, Storage, Key Vault, Azure SQL or equivalent)

• Proven experience designing, implementing, and operating CI/CD pipelines for building, testing, and deploying (preferably using GitHub Actions)

• Experience leading technical design reviews and influencing architectural decisions across team and product boundaries

Desired Qualifications

• Demonstrated ability to mentor Senior and Mid-level Engineers and partner with Engineering Managers on technical direction

• Hands-on experience working with relational databases, including schema design, indexing, and query performance optimization

• Hands-on experience designing and operating workflow-driven systems (orchestration, retries, timeouts, and state management)

• Experience integrating Machine Learning, Neural Networks or LLMs into enterprise applications and workflows

• Familiarity with OCR, NLP and computer vision technologies

Salary Range:

The anticipated base salary range for this position is between 300,000 PLN and 336,000 PLN annually. Base salary ranges may vary by geographic location and relevant experience, education, certifications, and seniority compared to others performing substantially similar work. There is no guarantee that an offer will be at the top of the posted range, as compensation decisions are based on a variety of factors including, but not limited to, skills, qualifications, and internal equity.
