About the Product:

The company develops an advanced monitoring and analytics platform for complex hardware systems. Using embedded data collection, large-scale analytics, and machine learning, the product captures data across development, production, and live operation, providing real-time visibility into system performance, quality, and reliability.

The platform processes large volumes of data in complex environments and helps customers prevent failures, optimize performance, and improve overall system quality.

About the Role:

As a Senior C++ Software Engineer on a core product team, you will own the full software development lifecycle for multi-architecture, cross-platform C++ modules that power advanced data processing and analytics systems. You will work in a small, self-sufficient team responsible end-to-end for a customer-facing product, collaborating with software, hardware, and research stakeholders. The role combines feature design and implementation with infrastructure ownership, CI/CD automation, and direct integration with customer environments. You will tackle performance-critical algorithms and complex system design, contribute to product direction, and maintain high standards of code quality in a fast-evolving environment.

Key Responsibilities:

• Design and implement cross-platform C++ software for Linux and Windows environments.
• Develop and maintain language bindings and interfaces using Python, Java and C#.
• Contribute to the full software development life cycle, including design, implementation, integration, testing, and deployment of software solutions for advanced test equipment.

• 7+ years of hands-on experience in production-grade C++ development (C++11/14/17) on both embedded and host systems.
• Proven experience designing and maintaining build systems, automation scripts and CI/CD pipelines (CMake, Bash, Docker, GitHub Actions).
• Deep understanding of data structures, algorithms, version control, performance optimization and test methodologies.
• Experience developing cross-platform software for Windows and Linux environments.
• Commitment to code quality: consistent formatting, clear conventions and thorough documentation.
• Strong interpersonal skills and ability to collaborate with distributed teams and customers.
• Proficiency in English communication, both written and verbal.
• Bachelor’s degree in Electrical, Computer or Software Engineering, Mathematics or Computer Science.

Nice to Have:

• Experience with Python, Java and C# in application integration.
• Familiarity with SQLite3 for embedded or application-level database use.
• Experience using SWIG to generate C++ bindings for high-level languages.
• Hands-on experience with post-silicon testing using Advantest or Teradyne automated test equipment.

About Our Client:

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads.

About the Role:

We are looking for a Middle-level Software Engineer to work on the core query engine of a large-scale distributed data platform. You will develop features across query planning, optimization, and execution, contribute to performance-critical components, and help investigate and fix production issues reported by real enterprise customers.

This is a systems-level, backend engineering role focused on distributed data processing internals — not application development or CRUD services.

Responsibilities:

• Develop and maintain features across the query engine — planning, optimization, execution, and data access layers
• Write performance-conscious code in Java and/or C++
• Investigate and fix production and customer-reported issues under the guidance of senior engineers, including fixes delivered across multiple supported release lines
• Work with SQL semantics, query plans, and execution operators over large-scale distributed data
• Integrate with columnar formats, open table formats, and connectivity drivers
• Contribute to CI/CD and automated testing in Jenkins
• Deploy and validate changes on Kubernetes (GKE/EKS/AKS) across GCP, AWS, or Azure with Docker
• Debug issues across query planning, distributed execution, memory management, and I/O; collaborate with US-based teams on design and code reviews.

Required Qualifications:

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field
• 3+ years in backend / systems software engineering
• Strong proficiency in Java or C++ with solid OOP and software design fundamentals, including concurrency and asynchronous programming (comfort with both languages is especially valued)
• Strong SQL and understanding of relational and analytical data systems, including query execution concepts
• Hands-on experience with data processing systems: query engines, distributed databases, ETL/ELT, or analytical platforms
• Experience with Jenkins pipelines and modern development workflows
• Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency)
• Hands-on experience with at least one major cloud (GCP, AWS, or Azure)
• Confident Git/GitHub workflows
• Comfortable with AI-assisted development workflows — using modern AI tools for code comprehension, debugging, and test generation, and critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings.

Desired Skills:

• Apache Arrow (columnar in-memory format) and SQL planner/optimizer frameworks such as Apache Calcite
• LLVM-based runtime expression compilation
• Open table formats — Apache Iceberg, Delta Lake, or Hudi — and columnar file formats such as Parquet, Avro, or ORC
• MPP query engines (Presto, Trino, or similar); exposure to distributed data platforms such as Spark, Snowflake, or Databricks
• Messaging systems: Kafka, NATS, or cloud pub/sub services
• Query planning, optimization, and execution internals
• Connectivity drivers: JDBC, ODBC, Arrow Flight
• Managed Kubernetes (GKE/EKS/AKS), multi-cloud exposure; Terraform
• Performance profiling of latency-sensitive systems.

Details:

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team

About EVIQO

EVIQO is one of the fastest-growing smart EV charging brands in the US residential market, serving customers across the US, Canada, and Europe soon.

We are already among the Top-5 market leaders in the US in our segment and continue scaling rapidly.

Our mission is to build a category-defining EV charging brand that competes with major players like Tesla, ChargePoint, and Autel.

Our core product is a premium Level 2 smart home EV charger combined with a mobile app and software platform that allows users to monitor and remotely control charging, manage and optimize energy consumption, automate charging sessions, and reduce electricity costs.

With up to 50 Amps of charging power, strong hardware positioning, premium customer experience, and a powerful D2C + Amazon growth engine, we are building much more than just a charger - we are building a scalable international brand.

We operate at the intersection of hardware, software, IoT, e-commerce, D2C, and international growth.

About the Role

The core focus of this role is conducting research and analyzing changes in key Amazon business metrics, including sales, sessions, advertising spend, market share, competitor activity, and other relevant performance indicators.

You will also prepare analysis and business scenarios to support the Head of Amazon in making key commercial decisions.

In addition to analytical work, you will be directly involved in executing Amazon-related tasks and will support the Head of Amazon in coordinating agreed growth initiatives across the PPC, Creative, and Account Management teams, ensuring their execution and tracking results.

This is not an administrative role or a traditional Personal Assistant position. We are looking for a strong, structured, hands-on professional who already has a deep understanding of the Amazon business and is ready to gradually take ownership of a larger part of the Amazon growth function.

Key decisions related to pricing, price elasticity, sales contribution margin, and overall commercial strategy will remain the responsibility of the Head of Amazon.

Expected Outcomes

• Establish a systematic approach to monitoring key Amazon business metrics, market share, and competitor activity, and regularly identify significant changes, risks, and growth opportunities.
• Prepare high-quality analysis and business scenarios to support the Head of Amazon in making decisions related to pricing, promotions, sales contribution margin, and other growth initiatives.
• Independently manage agreed Amazon-related projects and ensure they are delivered within established timelines.
• Effectively coordinate agreed growth initiatives across the PPC, Creative, and Account Management teams and oversee their execution.
• Within the first 6 months, gradually take independent ownership of selected Amazon growth areas and significantly reduce the amount of operational and analytical work requiring the direct involvement of the Head of Amazon.

Competencies

• 4+ years of hands-on experience working with Amazon / Seller Central. Experience in consumer electronics or other highly competitive categories is strongly preferred.
• Strong understanding of Amazon metrics and the relationships between revenue, sessions, CVR, organic ranking, PPC, pricing, coupons, promotions, and profitability.
• Strong analytical skills, including advanced Excel / Google Sheets proficiency and the ability to quickly work with large datasets, identify patterns, and translate them into clear business insights. Experience building automations and analytical workflows using AI tools is a significant advantage.
• High level of independence and ownership: ability to identify problems or opportunities proactively, propose solutions, and drive tasks through to completion.
• Strong organizational and execution skills: ability to manage multiple workstreams simultaneously, prioritize effectively, and avoid unnecessary bureaucracy.
• English level B2 or higher, with the ability to communicate professionally both in writing and verbally with internal teams and external partners.

Why Join EVIQO

• Work in a fast-growing international product company.
• Make a direct impact on business growth.
• Freedom to take ownership and implement ideas.
• Competitive compensation and growth opportunities.
• Fully remote work format.
• Working schedule: 10:00–19:00 (Kyiv time), including a 1-hour lunch break.
• 15 working days of paid vacation per year (available after 6 months of employment).
• 5 paid sick days without medical certificates.
• Sports and professional development compensation after successful completion of the probation period.

We’re looking for a Junior Front-End Engineer (with React Native Expo experience) to join our team. 

Work Location: Poland (Krakow), Slovakia (Kosice) or Czechia (Prague). 

Hybrid: 2+ days per week in the office, the rest remote.

The Mission

We are building a complex, real-time ecosystem for micromobility and logistics systems sim—where split-second logistics meet seamless user experiences. We need a Junior Front-End to work on the development of our Customer Mobile Web App and our high-utility Internal Admin Panels.

You’ll be the bridge between the sleek, high-performance interface our users see and the robust, scalable Python services that power the logic.

• Mobile-First Frontend: Architect and scale our React-based mobile web application, ensuring 60fps performance and offline-first capabilities.
• Operational Control Centers: Build dense, data-heavy Admin Panels that allow our operations team to monitor real-time logistics, manage users, and handle complex dispatching.
• Scalable Backend: Design and maintain performant APIs using Python (FastAPI/Django) to handle high-concurrency event streams.
• End-to-End Ownership: From database schema design to CSS transitions, you’ll own the entire feature lifecycle.

Who You Are

• The Architect: You don't just "write code"; you design systems. You understand how a change in a Python microservice ripples out to the React frontend.
• UX Enthusiast: You understand that an Admin Panel requires different UX "muscle" (efficiency and density) than a mobile app (simplicity and speed).
• Problem Solver: You’ve dealt with the "hard stuff"—real-time GPS tracking, race conditions in booking logic, or complex state management.
• Pragmatist: You balance the need for clean, tested code with the reality of shipping features in a fast-paced environment.

Will be a plus Led transformation of standalone product into scalable SaaS platform.

We’re looking for a Junior Backend (Python) Engineer to join our team. 

Work Location: Poland (Krakow), Slovakia (Kosice) or Czechia (Prague). 

Hybrid: 2+ days per week in the office, the rest remote.

The Mission

We are building a complex, real-time ecosystem for micromobility and logistics systems sim—where split-second logistics meet seamless user experiences. We need a Junior Backend (Python) Engineer to work on the development of our Customer Mobile Web App and our high-utility Internal Admin Panels.

You’ll be the bridge between the sleek, high-performance interface our users see and the robust, scalable Python services that power the logic.

Key Responsibilities

• Mobile-First Frontend: Architect and scale our React-based mobile web application, ensuring 60fps performance and offline-first capabilities.
• Operational Control Centers: Build dense, data-heavy Admin Panels that allow our operations team to monitor real-time logistics, manage users, and handle complex dispatching.
• Scalable Backend: Design and maintain performant APIs using Python (FastAPI/Django) to handle high-concurrency event streams.

• End-to-End Ownership: From database schema design to CSS transitions, you’ll own the entire feature lifecycle.

   

Who You Are

• The Architect: You don't just "write code"; you design systems. You understand how a change in a Python microservice ripples out to the React frontend.
• UX Enthusiast: You understand that an Admin Panel requires different UX "muscle" (efficiency and density) than a mobile app (simplicity and speed).
• Problem Solver: You’ve dealt with the "hard stuff"—real-time GPS tracking, race conditions in booking logic, or complex state management.
• Pragmatist: You balance the need for clean, tested code with the reality of shipping features in a fast-paced environment.

Will be plus Led transformation of standalone product into scalable SaaS platform.
