Senior C++ Engineer

We are seeking a Senior C++ Engineer to collaborate with Data Scientists and Machine Learning experts in transforming prototype algorithms into hardened, reliable, production-grade applications. In this role, you will convert research workflows into high-performance C++ systems capable of running on resource-constrained hardware or scalable cloud environments.

Responsibilities

• Collaborate closely with Data Scientists and Machine Learning experts to turn prototype algorithms and data processing pipelines into hardened, reliable, production-grade "always-on" applications written in C++
• Conversion of research and prototype ML/data-processing workflows (primarily Python-based) into high-performance, reliable C++ production systems
• Implementation of data quality safeguards, sanitization and required low-level interfaces for real-time inference on streaming data
• Optimization of code for predictable behavior, high reliability and efficient resource utilization (compute/memory/storage) on resource-constrained environments
• Support the development of high-performance, high-reliability solutions capable of running on resource-constrained hardware or in cost-effective, highly-scalable cloud applications
• Translation of real-world process dynamics, sensor behavior and system constraints into realistic online control solutions
• Documentation and communication of assumptions, results, limitations, risks and deployment considerations for discussion with the broader technical audience

Requirements

• 5+ years of experience in modern C++ software development using C++17/C++20
• Understanding of multithreading, concurrency, synchronization and performance optimization in Linux environments
• Background in developing deterministic, low-latency software for real-time systems
• Proficiency in CMake, modern C++ build systems and Conan package management for C++
• Skills in profiling and optimizing CPU/memory utilization in constrained Linux environments
• Competency in writing unit tests and automated tests
• Proven capability to debug low-level communication issues and optimize performance under constrained environments
• Hands-on expertise designing, deploying and debugging containerized applications using Docker in Linux production environments
• Experience with CI/CD & Release pipelines: multi OS runners, artifact signing, SBOMs/vulnerability scanning
• Familiarity with Agile toolsets such as Azure DevOps, Atlassian tools like Confluence, JIRA and Bitbucket
• Fluent English communication skills at a B2+ level

Nice to have

• Capability to independently deploy and manage cloud-native or edge-native microservices in Linux environments
• Flexibility to work closely with research, data science and platform engineering teams to bridge prototype and production environments
• Skills in Python and C++ interoperability
• Familiarity with industry IoT standards and protocols such as MQTT/SparkplugB, ZeroMQ, ProtoBuf, Kafka and HTTP
• Expertise in Linux, Bash/Shell scripting, Docker, TCP/IP networking, Kubernetes, systemd, logging, OTA/rollback strategies and advanced debugging techniques
• Background in deploying software in industrial environments, including remote diagnostics and field support
• Familiarity with .NET/C#

We offer

• Engineering community of industry professionals
• Friendly team and enjoyable working environment
• Flexible schedule and opportunity to work remotely within Poland
• Chance to work abroad for up to 60 days annually
• Business-driven relocation opportunities
• Outstanding career roadmap
• Leadership development, career advising, soft skills, and well-being programs
• Certification (GCP, Azure, AWS)
• Unlimited access to LinkedIn Learning, Get Abstract, Cloud Guru
• English classes
• Stable income (Employment Contract or B2B)
• Participation in the Employee Stock Purchase Plan
• Benefits package (health insurance, multisport, shopping vouchers)
• Strategically located offices featuring entertainment and relaxation zones, table tennis and football, free snacks, fantastic coffee, and more
• Referral bonuses
