Staff Engineer (Satellite Communications)

ICEYE Oy; Espoo; Hybrid; EUR 90,000 - 140,000; Full time

Job summary

ICEYE Oy is seeking a Staff Engineer in Espoo, Finland to own the satellite-to-ground link and end-to-end data transmission from ground stations to customers. You will work across the stack from cloud to real hardware, contributing code and shaping design decisions.

You will lead the architecture for X-band, Ka-band and S-band links, define latency commitments, and mentor teams as ICEYE scales its constellation and data delivery capabilities.

Qualifications

• Experience engineering on at least one flown satellite mission.
• High-rate X-band/Ka-band downlink experience beyond S-band.
• Ability to build and defend a link budget: EIRP, G/T, Eb/N0, margin, rain fade.
• Practical CCSDS knowledge: transfer frames, virtual channels, synchronisation and coding.
• Experience moving data from ground to consumer with latency guarantees.
• Hands-on coding in Python, Go, C++ or similar; you ship code.

Responsibilities

• Own the architecture of the satellite-to-ground link across X-band, Ka-band payload downlink and S-band C2.
• Measure constellation delivery against theoretical capacity and close gaps.
• Design data movement from ground stations to customers with latency tiers and delivery accounting.
• Build alongside software engineers, contributing code and reviews.
• Lead technical initiatives across team boundaries and align teams on data path decisions.
• Grow satellite communications expertise through mentoring and design reviews.

Job description

Role highlights:

• Staff Engineer - Satellite Communications
• Location: Espoo, Finland
• Department: Fleet Control and Satellite Communications
• Reports to: Director, Fleet Control and Satellite Communications
• Employment type: Permanent
• Workplace model: Hybrid. 3 days a week at the office
• Employment is subject to applicable security screening (incl. SUPO, where required)

Why this role matters:

As a Staff Engineer in Satellite Communications, you will own the satellite-to-ground link, the core communications protocols, and the end-to-end transmission of data from ground stations to customers. Trend is that our constellation produces an increasing volume of data and we want it down faster and more reliably. As we scale, the communications link sets the limit on what we deliver and how fast customers receive it.

You’ll own the end-to-end communication stack: the satellite-to-ground link (X-band, Ka-band and S-band), the underlying protocols used, and the transmission of data from ground stations to customers. Today these decisions are spread across several teams. This role brings them under one technical owner.

The work sits where software meets physics. On one side are link budgets, modulation and coding, and spectrum constraints; on the other are schedulers, distributed systems and production operations. The hardest problems live where the two meet.

You own what you build, from design to production, across a stack that combines cloud, on-prem and real hardware. Our engineering culture is AI-positive, with active use of copilots and LLMs to improve speed, code quality and productivity.

Who We Are

ICEYE is the world leader in sovereign intelligence from space. We deliver persistent monitoring capabilities to detect and respond to changes in any location on Earth.

ICEYE owns the world's largest and most advanced SAR (synthetic aperture radar) satellite constellation. To our customers we provide intelligence with unmatched quality, latency and revisit times, in any weather, day or night. To governments who choose to operate their own constellation we provide this proven capability as a sovereign system.

ICEYE-built constellations serve customers in defence and intelligence, environmental monitoring, insurance and emergency management. We enable fast decisions that contribute to a safer future.

Founded and headquartered in Finland, ICEYE operates globally with over 1000 employees across Europe, North America, the Middle East, and Asia-Pacific.

Your day-to-day responsibilities

• Own the architecture of the satellite-to-ground link acrossX-band and Ka-band payload downlink and S-band command and control
• Measure what the constellation delivers against its theoretical capacity, and lead the work that closes the gap
• Design how data moves from ground station to customer, including latency tiers and delivery accounting
• Build alongside software engineers, contributing code and reviews, not only architecture documents
• Lead technical initiatives across team boundaries and align teams on link and data path decisions
• Grow satellite communications expertise across the domain through mentoring, design reviews and shared standards

What we're looking for

Must haves:

• Communications engineering on at least one flown mission, including personally diagnosing an anomaly on a live satellite.
• High-rate payload downlink experience in X-band or Ka-band, beyond S-band command and control
• Ability to build and defend a link budget: EIRP, G/T, Eb/N0, margin, rain fade, elevation constraints
• Practical CCSDS knowledge: transfer frames, virtual channels, synchronisation and channel coding, file delivery
• Experience owning how data moves from a ground station to where it is consumed, with latency and completeness guarantees
• Hands-on coding in Python, Go, C++ or similar; you ship code, not just designs.

Nice to haves:

• Active use of AI-assisted development tools (e.g., copilots, LLMs) to improve productivity, code quality, and problem-solving.
• Fleet-scale contact planning and scheduling across commercial ground station networks, especially leased third-party capacity
• DVB-S2/S2X with adaptive coding and modulation
• Delay-tolerant networking, or other store-and-forward file delivery with completeness accounting
• SDR and DSP work: GNU Radio, FPGA or RFSoC, including personal or open-source projects
• Awareness of spectrum regulation and coordination. We have a separate spectrum licensing team, so this is a plus rather than a requirement

Application Process

• TA Partner Screen Call (30 min)
• Hiring Manager Interview (90 min)
• Technical Interview (120 min)
• Values and Fit Interview (60 min)
• Final interview with SVP of Engineering (60min)
