Jobs

Our company is developing its own interactive knowledge base. Users can upload any volume of diverse data, after which the system automatically transforms it into structured, searchable content. To achieve this, we use a comprehensive ML pipeline involving OCR, vision-language models, document parsers, and multiple types of data storage. Search is implemented through an LLM-based chat interface that allows users to submit queries in natural language, retrieve relevant documents, and receive summarized findings and recommendations based on the uploaded materials.

We are currently looking for an ML/AI Engineer with deep experience working with unstructured content - primarily photographs and scanned document copies - who will strengthen our team and lead the development of pipelines and solutions for processing this type of data.

We expect the candidate to:

• Have broad experience working with unstructured data and have used both classical OCR systems (Tesseract, PaddleOCR, EasyOCR) and modern models (PaddleOCR-VL, DeepSeek-OCR, dots.ocr, Qwen3-VL). Understand the strengths and weaknesses of different architectures and the scenarios in which each is most effective.
• Have hands-on experience training and fine-tuning OCR and Vision-Language models.
• Understand algorithmic approaches to image enhancement, preprocessing, and filtering in order to improve downstream recognition quality.
• Have worked with Docling (including advanced backend tuning for parsing complex PDFs and tables), markitdown, Apache Tika, PyMuPDF, and other tools for document conversion and structuring. Be comfortable with processing layered and non-trivial PDF files.
• Have experience working with self-hosted models, including deploying and optimizing models in vLLM environments on H100-class GPUs and above, and understand the principles of GPU architecture and KV cache.
• Have strong Python programming skills, including architectural patterns, multithreading, asynchronous programming, modern testing practices, and experience operating services under high load (monitoring, telemetry, memory utilization).
• Have experience working with document-oriented, relational, and vector databases, and understand index types and the relevant use cases for each type of storage.

It would be a plus if you have:

• Experience working with Speech-to-Text or Video-to-Text pipelines.
• Experience in content analysis, including classification, summarization, and NER.
• Experience in data engineering: understanding of ETL/ELT processes, experience with orchestrators (Airflow, Temporal, Prefect), and distributed computing systems (Ray, Spark).
• Experience in DevOps: CI/CD, Kubernetes, Helm, ArgoCD.
• Experience working with Elasticsearch, MongoDB, PostgreSQL, Qdrant/Milvus, Neo4j, and other storage systems.
• Understanding of modern cybersecurity approaches.
• Hands-on experience with production-grade RAG-based systems.

We offer a fully remote work format on our own product, which uses state-of-the-art technologies and is focused on the public sector. The company has the status of being critically important to the Armed Forces of Ukraine. If needed, we provide military deferment and the necessary office equipment.

Пропонуємо повністю віддалений формат роботи над власним продуктом, який використовує найсучасніші технології та орієнтований на державний сектор. Компанія має статус критично важливої для Збройних сил України. За потреби надаємо бронювання та необхідну офісну техніку.

Petcube is looking for an Embedded Tech Lead to own the technical direction of our hardware and firmware platform across multiple product lines (cameras and GPS trackers). You’ll be the person who makes the key architectural and system-level decisions, ensures production readiness, and builds a sustainable engineering culture within a small, high-impact team. This is a leadership role first — you’ll guide and support engineers rather than write the majority of the code yourself.

What You’ll Do

• Define and evolve the platform architecture across Petcube’s embedded products
• Make key technical decisions around hardware, firmware, and system design
• Own production readiness: guide products from prototype through mass production and ongoing maintenance
• Mentor and support firmware engineers through code reviews, technical discussions, and design feedback
• Communicate technical risks, trade-offs, and timelines clearly to product and management
• Balance short-term delivery pressure with long-term platform quality and technical debt management

• Drive cross-team alignment on technical decisions that affect firmware, hardware, backend, and mobile

   

What We’re Looking For

• 7+ years in embedded engineering with progressive technical leadership
• Experience launching hardware products from prototype to mass production (must-have)
• Experience working across multiple hardware generations
• Strong system-thinking mindset — ability to see how firmware, hardware, cloud, and mobile interact
• Familiarity with both Embedded Linux and MCU/RTOS environments (doesn’t need to be expert in both, but needs to understand both worlds)
• Track record of mentoring engineers and improving team practices
• Startup or early-stage product company experience (strong plus)

• Willingness to roll up sleeves when needed, but primary value is in direction, not daily code output

   

Tech Stack Across the Platform

C/C++, Embedded Linux, Zephyr RTOS / FreeRTOS, BLE (Nordic), GPS, cellular (LTE-M/NB-IoT), Wi-Fi, IMU, Yocto, CMake, low-power design, video streaming and networking.

Location: Remote — EU (Poland, Romania, Czech Republic, Germany, Slovenia, Estonia, Latvia, Greece, Hungary), US, or Canada

Why This Role

You’ll be the technical leader of the entire embedded platform at a company where firmware is the product. No layers of management between you and the decisions that matter. You’ll shape how the next generation of Petcube devices is built, mentor a small team of strong ICs, and have a direct line to the CTO. If you’ve been looking for a role where your technical judgment genuinely drives the product, this is it.

Petcube is looking for a Firmware Engineer to own the firmware for our GPS pet tracker product. This is a deeply technical, hands-on role working with BLE microcontrollers, Zephyr RTOS, and low-power wireless technologies. You’ll be building features, improving existing functionality, and documenting a codebase that often requires a reverse-engineering mindset to understand fully.

What You’ll Do

• Develop and ship new firmware features for the Petcube tracker
• Reverse-engineer and document existing firmware behavior where documentation is lacking
• Clarify and define device behavior in collaboration with product and QA
• Conduct and participate in code reviews
• Optimize for low-power operation and connectivity reliability

• Contribute to the long-term evolution of the tracker platform across hardware generations

   

What We’re Looking For

• 3+ years of firmware development experience on microcontrollers
• Strong C/C++ skills in bare-metal or RTOS environments
• Experience with Zephyr RTOS, FreeRTOS, or similar
• Hands-on experience with BLE (Nordic nRF or similar)
• Familiarity with low-power design, GPS, cellular (LTE-M/NB-IoT), Wi-Fi, or IMU
• Experience with CMake build systems

• Comfort working in a codebase with limited documentation and the patience to improve it

   

Location: Remote — EU (Poland, Romania, Czech Republic, Germany, Slovenia, Estonia, Latvia, Greece, Hungary), US, or Canada

Why This Role

This isn’t a role where you’ll write firmware for one peripheral and hand it off. You’ll own the entire tracker firmware stack — from BLE communication to GPS positioning to power management. It’s a consumer product used by real pet owners every day, and your decisions will directly shape how it performs. If you want full ownership of a product’s firmware without the overhead of a large organization, this is it.

Join our expanding team as a Senior Python Engineer! We’re looking for a proactive tech professional who takes ownership, sweats the details, and takes pride in delivering high-quality software.
