Top Tech Jobs & Startup Jobs

Build and maintain React-based user interfaces, collaborate with designers and backend developers, write tests, improve UI/UX and performance, and troubleshoot technical issues.

Design, develop, and maintain IPv6 networking features for enterprise/ISP-grade router firmware. Implement IPv4–IPv6 coexistence (dual-stack, tunneling, NAT64, DS-Lite, MAP-E), perform performance tuning and troubleshooting, define roadmap with product and system teams, and collaborate with QA to create test plans and automated IPv6 test environments.

Lead mechanical product design from concept through mass production for power and battery products. Create 3D models and engineering drawings, select materials and processes, resolve tooling and manufacturing issues, plan and execute testing, and research emerging materials and standards to ensure reliable, compliant products.

Design and validate PCB schematics and layouts for Ethernet/wireless PDU/UPS products, manage BOM and lifecycle, collaborate with RF, SI, mechanical teams, run test/validation and reliability checks, and perform market teardowns and competitive analysis to enable mass production.

Lead backend architecture and code decisions, participate across projects, design secure scalable APIs, review code and deployment workflows, and collaborate with product, embedded, mobile, and frontend teams to deliver production services.

Design, verify, and review hardware circuits and PCB layouts for Ethernet switches and routers. Support BOMs, production, NPI/MP/EOL phases, RMA failure analysis, and cross-functional collaboration. Recommend technologies and ensure compliance with ESD, surge, safety, and regulatory requirements.

Design, develop, and optimize IPv6 networking features for enterprise router firmware, ensure IPv4/IPv6 coexistence, perform performance tuning and troubleshooting, and collaborate with product, architecture, and QA teams for IPv6 roadmap and testing.

Work with firmware, digital and RF hardware engineers to test and validate wireless broadband products. Perform embedded firmware testing on Linux, write bash/python scripts, maintain and enhance Jenkins CI, and follow software development lifecycle practices. Hybrid role based in Kyiv; must understand 802.11 and L2/L3 networking.

Build and maintain high-performance Node.js backend services for UniFi Protect, design modular embedded-friendly architectures, implement low-latency network communication and RESTful APIs, integrate real-time video streaming and storage, optimize backend performance, collaborate with cross-functional teams, write tests, monitor production, and contribute to architectural decisions and innovation.

Perform primarily manual regression, exploratory, and issue verification testing, maintain MQA lab setups, contribute to test planning/estimation, and perform limited automation (10%). Focus on backend testing and L3-L4 networking in a hybrid Kyiv-based role.
