Embedded C/C++ Development • AI-Assisted Engineering • Hardware Bring-up & Debugging

Location: Remote (EU Time Zones)
Reports to: Embedded Systems Engineering Manager 
Level: Senior (a strong middle+ with the right depth is welcome)

About WOWCube

WOWCube is a gaming console shaped as a puzzle cube: eight modules with 24 screens that act as one device. We build the hardware, our own operating system (OctaviOS), the system apps and the dock station. The current cube is shipping, the next generation is in bring-up. 

About the role

You will join the embedded team and own whole subsystems of OctaviOS - from design to a release proven on real devices. AI coding agents are part of our everyday toolset and write a large share of the code; the engineer owns the design, keeps the codebase free of technical debt and is responsible for the solution working completely. That means deliberate development with full control over what the agents produce. We are looking for an engineer who turns this way of working into a multiple of a conventional developer's output and works well with the team.

Main responsibilities

• Design, implement and debug C firmware for an ARM Cortex-M / RTOS platform: drivers, system modules, connectivity, power management etc.
• Own features and fixes end-to-end: requirements, design, implementation, tests, verification on devices, release.
• Bring up new board revisions and build the diagnostics for hardware testing.
• Find root causes of crashes, memory corruption, timing and radio issues; prove fixes on hardware.
• Use AI coding agents daily and keep them under control: prepare the context (architecture, hardware constraints, coding rules), review every change for correctness, reuse and size, improve the shared agent setup.

• Review colleagues' work, keep design notes and tests current.

   

Requirements

• 5+ years of firmware development; at least one shipped consumer device.
• Strong C (working C++) on ARM Cortex-M with an RTOS; comfortable with schematics, datasheets, a debugger and a logic analyzer.
• Solid low-level knowledge: memory layout, DMA and caches, interrupts and timing, power management, a radio stack (BLE or similar), serial protocols.
• Experience bringing up a new board and validating firmware on physical devices.
• Systems thinking and a disciplined approach to debugging: reproduce, measure, prove - and the judgment to know when that rigour is needed and when a quick fix is right.
• Daily use of AI coding agents (Claude Code or similar) in real projects, with the judgment to tell good generated code from plausible-looking bad code and the discipline to keep generated changes small, reusable and debt-free.

• A team player: argues with evidence, accepts decisions once made, communicates clearly in writing, flags risks early.

   

Nice-to-Have

• Python for tooling and test automation.
• Vendor SDK bring-up on a less-documented SoC; RTOS internals.
• 2D graphics or game-engine work on constrained hardware.
• Hardware-in-the-loop or factory test rigs; EVT/DVT/PVT experience.

• Rust, MQTT, battery chargers and gauges.

   

How we work

• Small PRs, host tests and CI on every push; a short design note for every mechanism; zero technical debt.
• A bench (cube and dock) at your desk; tooling to flash, install and read telemetry remotely.
• English for code and documentation; remote, async-friendly, EU hours.

About Sine Engineering

Sine Engineering builds the technology behind reliable drone autonomy, delivering communication, navigation, and control systems that enable coordinated multi-drone operations. More than 200 UAV manufacturers rely on our solutions, and our technology powers many of the interceptor operations active today.

Through our dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological advantage.

Any drone, any scale, anywhere — resilient communication, navigation, and coordination built for the age of autonomy. Our products have already proven their effectiveness in real combat conditions in Ukraine.

About the Role

We are looking for a Delivery Manager to own the technical direction and delivery of projects across a portfolio of strategic customer accounts.

This role bridges client needs and engineering execution. You will engage early, often before a solution or delivery scope is fully defined, to understand the client’s platforms, operational use cases, technical constraints, and future plans. You will then translate that understanding into a realistic technical roadmap and coordinate its implementation with Client Integrations, Product, Demo, Military Support, and other engineering teams.

You will work closely with a Key Account Manager. While the Key Account Manager owns the overall account strategy, customer relationship, and commercial outcomes, you will be responsible for the technical account plan, solution feasibility, and successful technical delivery.

This is neither a traditional sales role nor a purely administrative project management position. It requires sufficient engineering depth to make and defend technical decisions, combined with the ability to lead complex, customer-facing initiatives across multiple teams.

Responsibilities

Technical Account Ownership

• Maintain a comprehensive and up-to-date technical view of each assigned account, including client platforms, system architecture, completed and planned integrations, operational use cases, risks, and dependencies.
• Develop and maintain a technical account roadmap aligned with the Account Development Plan and the client’s product and platform development strategy.
• Participate in customer discussions before scope commitments are made, ensuring technical feasibility, constraints, effort estimates, and dependencies are clearly understood.
• Translate customer and operational requirements into a well-defined technical scope, integration approach, delivery plan, and acceptance criteria.
• Own solution feasibility and technical commitments for assigned accounts.
• Identify technically viable opportunities to expand Sine solutions across additional customer platforms, products, and use cases.
• Build trusted relationships with customers’ engineering and technical teams.
  Technical Delivery
• Own the technical outcomes of discovery activities, integrations, proof-of-concepts (PoCs), demonstrations, and acceptance testing.
• Define project concepts in collaboration with engineers and technical specialists.
• Establish technical milestones, dependencies, risks, test objectives, and acceptance criteria.
• Assemble and align the appropriate technical team for each opportunity based on scope and complexity.
• Coordinate engineers and technical contributors who do not necessarily report directly to you.
• Monitor delivery progress and proactively escalate technical risks, resource constraints, and scope changes.
• Ensure technical decisions, configurations, test results, and known limitations are properly documented.
• Facilitate smooth handover from internal teams to customer deployment, support, or ongoing development.

Required Qualifications

• Experience delivering complex hardware, embedded systems, or system integration projects for external customers.
• Ability to understand system architecture and make sound technical decisions.
• Experience translating customer or operational requirements into technical scopes and implementation plans.
• Experience coordinating multidisciplinary engineering teams and specialists without direct reporting authority.
• Ability to estimate technical effort, identify dependencies, and assess delivery risks.
• Strong customer-facing communication skills, including the ability to explain technical limitations and navigate challenging delivery discussions.
• Structured approach to planning, documentation, risk management, and reporting.
• Professional working proficiency in both English and Ukrainian.
• Willingness to travel to customer sites as required.

Nice to Have

• Engineering background or strong technical expertise in UAVs, robotics, embedded systems, RF communications, navigation systems, electronics, or a related field.
• Experience in defense technology, UAVs, UGVs, autonomy, communications, RF systems, ISR, electronic warfare (EW), or GNSS-denied navigation.
• Experience as a Technical Account Manager, Solutions Architect, Integration Lead, Technical Project Manager, or Engineering Delivery Lead.
• Understanding of UAV subsystems, including telemetry and control links, video transmission, flight controllers, navigation systems, antennas, onboard electronics, and ground control stations.
• Experience with field testing, flight testing, demonstrations, or formal customer acceptance processes.
• Experience collaborating with Product and R&D teams to address customer-driven product requirements.
• Experience working with military users, defense organizations, or operational support teams.
• Experience coordinating external engineering partners, vendors, or subcontractors.

Why Join Us?

• If you’re excited about building technology that shapes the future of drone autonomy and want your work to have a meaningful impact on defense and security, we’d love to hear from you.
• If this role aligns with your experience and ambitions, don’t hesitate to apply. We’re looking for people who share our drive to push the boundaries of what’s possible and deliver technologies that make a real-world difference.

As the Software Engineer, you will own the software around the exoskeleton in Kyiv: the phone app that soldiers and testers use to control the device, and the system that records what every unit does, so engineering can see which units exist, what version they run, and what happened in every test. The core firmware team that makes the exoskeleton walk is in overseas. You will be the software owner in Kyiv, close to the units and the soldiers.

You will report to the Ukraine Director and work every day with colleagues internationally, as the link between what we see in the field and what the main engineering team needs to fix.

This is a hands-on ownership role. You should thrive in a fast-paced, dynamic environment, be comfortable making decisions independently, and bring the energy, attitude, and ownership to move fast and finish things. The responsibilities below are in priority order right now. They will change as we grow, and you will help decide how.

Responsibilities

• Take over our existing phone app on day one: make it work with the newest hardware, and keep it updated every time the device changes
• Make the app easy for a soldier to install and use, in Ukrainian and English
• Build and maintain one always-up-to-date list of every exoskeleton: serial number, hardware version, software version, settings, and repair history
• Get the data each unit records during a test off the device and into a database, so test results, errors, and usage are stored and searchable instead of living in chats and spreadsheets, built to work for 10 units and for 10,000
• Build simple web pages and dashboards for the field team, engineering, and customers
• Update, recover, and read logs from any unit in Kyiv without waiting for anyone
• Give the firmware team clear, specific feedback, and make small changes with them when needed
• Take ownership of problems and make fast, practical decisions without waiting for detailed direction

Basic Qualifications

• Proven track record of building and shipping a real product, mostly on your own, with links, app store pages, or repositories to show it.
• Strong on both the app side (mobile or web) and the data side (databases, data pipelines, and APIs). The programming languages or tools you use do not matter.
• Comfortable with low-level code (C or C++, embedded devices, serial and Bluetooth connections), enough to debug a device and talk to firmware engineers as an equal. You do not need to be a firmware expert.
• Clearly excellent at what you do, with lots of energy, a habit of taking ownership, and a record of moving fast and finishing things.
• Working English for daily collaboration with colleagues internationally, and Ukrainian for work in Kyiv.
• Comfortable around hardware and soldiers.
• Based in or willing to relocate to Kyiv, able to work full time in the office.

Preferred Skills and Experience

• Experience with embedded or IoT devices, or hardware testing
• A mobile app published on the App Store or Google Play
• Experience building data pipelines for device or sensor data

How We Work

Hardware reaches real operators within days of concept, not months, and firmware updates ship over the air every one to two weeks. We are a small team with one owner per category. Nobody owns a slice of someone else’s problem.

Additional Requirements

Location: Kyiv, full time, in the office
Start: As soon as possible

What are you going to do? 

We're looking for a product designer to help create and shape our products: fuel and loyalty platforms built for the US market. You'll lead projects end to end, working closely with engineering and stakeholders, and you'll help stand up design practice in our team. We expect a broad range of design skills, exceptional taste, and fluency with the latest AI design workflows. 

What you'll own 

• Design end to end across our vendor-facing and internal surfaces: research, flows, UI, and the details that make it usable at volume. 
• Work directly with product and engineering from the start of a problem, not just at handoff, shaping what gets built and not only how it looks. 
• Use AI-assisted design and prototyping tools as part of your default workflow, moving from idea to tested design fast, and help bring those workflows into our existing legacy designs. 
• Establish research and customer insight practice, so evidence is embedded from problem framing through delivery. 
• Drive competitor and market analysis, including the best current design patterns and industry examples, and use it to shape design direction and inform strategic priorities across teams. 
• Ground decisions in analytics and real usage data rather than preference alone. 
• Build and maintain a design system that holds up as the product and the team grow. 
• Give engineering enough clarity to build confidently, without needing pixel-perfect specs for everything. 

Requirements 

• 5+ years designing digital products for mobile and web. 
• A portfolio that demonstrates both design sensibility and real product depth. 
• Demonstrated research ability: you can plan it, run it, and turn it into direction. 
• Fluency with AI tools, with the ability to work directly in code rather than relying solely on prompts. 
• Strong Figma fundamentals: components, auto layout, variables, and systems that hold up under other people's hands. 
• Excellent communication, with a track record of working effectively with US-based stakeholders. 

Nice to have 

• Experience in retail, fueling, or loyalty domain products. 
• Experience improving user flows in complex domains with a large user base and high event volume. 
• Motion and brand design skills you can apply to product and marketing surfaces.
