• Job Title: Orbit Determination Software Engineer
• Department: Spacecraft Analysis, Orbit and Attitude Control
• Espoo, Finland / Warsaw, Poland
• Reports to: Engineering Lead, Orbit Determination
• Type of employment: Permanent / Hybrid
• Employment is subject to applicable security screening (incl. SUPO)

Who We Are

ICEYE delivers space-based intelligence, surveillance, and reconnaissance (ISR) capabilities to governments and allied nations. This includes sovereign and turnkey ISR missions leveraging ICEYE’s world-leading synthetic aperture radar (SAR) satellite technology, as well as access to data from the world’s largest SAR satellite constellation. These capabilities enable partners to detect and respond to critical changes anywhere on Earth with unprecedented speed and accuracy – day or night and in any weather, supported by ultra high-resolution imagery and high-frequency revisits.

As a trusted partner for defense, intelligence, security, and maritime domain awareness, ICEYE’s near real-time data creates a tactical advantage for mission-critical operations. Designed for dual use, the platform also serves civil protection and commercial users for natural-catastrophe intelligence, insurance, maritime monitoring (including oil-spill detection), and finance, contributing to global security and community resilience.

ICEYE operates internationally with offices in Finland, Poland, Spain, Japan, the UAE, Greece, and the US. The company has more than 900 employees, inspired by the shared vision of improving life on Earth by becoming the global source of truth in Earth Observation.

Why this role?

In this role you will ensure that orbit determination products are always available for our internal and external customers.

You will be a part of a multidisciplinary team of software and flight dynamics engineers working on a critical part of our systems, which computes high accuracy estimates of where our satellites have been and where they are going to be. The role is critical in ensuring the Orbit Determination software service is always ready to provide high-accuracy estimates across a number of different deployment configurations, including Cloud and on-prem environments.

You will tackle significant engineering challenges involving high-availability distributed systems, network communication and telemetry processing. You will work closely with satellite operations and mission planning teams to turn complex physical constraints into robust, automated software solutions.

What you’ll do

• Design, develop, maintain, and test orbit determination software responsible for tracking ICEYE’s fleet of satellites and modeling the evolution of their position and velocity over time
• Develop and ship production-ready software services running on containerized in-prem and cloud environments.
• Own and debug operational issues related to the software. ICEYE engineers own all the stuff they build, end-to-end.
• Collaborate with a multidisciplinary team to balance high-fidelity state estimation with high-availability and low-latency data delivery

• 5+ years of software engineering experience with a history of designing, developing, and delivering software systems running in containerized environments
• Professional experience working with CI/CD, code reviews, and unit tests
• Experience working with databases to store and retrieve data in a timely manner, ideally using TimescaleDB and/or InfluxDB
• Practical experience implementing and maintaining REST APIs
• Experience writing software in Python and Java
• Basic familiarity of cloud and infrastructure technologies such as AWS, AWS SQS, Docker, Kubernetes, and Terraform or similar
• Interest in learning about the domains of astrodynamics and orbit determination
• Able to communicate complex software concepts in plain English

Nice to have

• Knowledge of state estimation principles such as Kalman filtering, measurement processing, state propagation, and statistical analysis
• Experience working with Grafana and Datadog for logging and data analysis
• Experience designing and operating high-availability services
