Your work will focus on optimization, scheduling, operational automation, and high-performance backend services across Quindar's platform. You'll work primarily in Python to build reliable production systems that solve computationally demanding planning problems. These systems must process large search spaces, respond with low latency, and scale from individual spacecraft to large satellite constellations. You'll develop and validate algorithms, design distributed services, and improve the performance and operational resilience of mission-critical workflows. This role sits at the intersection of optimization, backend software engineering, and space operations. You'll collaborate closely with software engineers, flight dynamics engineers, satellite operators, frontend engineers, and product leaders to turn complex operational requirements into maintainable and scalable software., Quindar encourages engineers to seek leverage through automation and AI-assisted development. We use modern engineering tools to accelerate implementation, deepen validation, improve debugging, and reduce operational friction while maintaining a high standard for correctness and reliability. In this role, you will: * Lead the design and implementation of mission-planning, scheduling, optimization, and operational-automation systems * Develop and validate algorithms that solve complex planning and resource-allocation problems across large solution spaces * Build high-performance APIs and distributed services for low-latency and compute-intensive workloads * Improve the scalability, reliability, observability, and operational readiness of mission-critical systems * Collaborate across software, program, product, and operations to turn complex requirements into robust production solutions * Help shape technical direction, mentor other engineers, and use automation and AI-assisted practices to improve engineering velocity and quality ## Related Videos - [Crew Management System for Airlines: Plan duties for pilots & flight attendants worldwide](https://www.wearedevelopers.com/videos/1444-crew-management-system-for-airlines-plan-duties-for-pilots-flight-attendants-worldwide) - [Swapping Low Latency Data Storage Under High Load](https://www.wearedevelopers.com/videos/746-swapping-low-latency-data-storage-under-high-load) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [How Lufthansa Industry Solutions is preparing for the Quantum Age! ](https://www.wearedevelopers.com/videos/1443-how-lufthansa-industry-solutions-is-preparing-for-the-quantum-age) - [Unleash the power of 5G in your code: transform your apps](https://www.wearedevelopers.com/videos/1567-unleash-the-power-of-5g-in-your-code-transform-your-apps) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again)
