Senior Backend Software Engineer

Join Spire, a leading satellite data and analytics company, as a Senior Backend Software Engineer. In this hands-on engineering role, you will design, build, and improve reliable and secure systems that support our satellite and ground infrastructure. You will collaborate with software, infrastructure, and cybersecurity teams to implement scalable solutions that support operational reliability and secure engineering practices. This position offers a range of benefits, including flexible time-off, family leave, and opportunities for personal development.

• Design, develop, and maintain backend services and platform tooling, ensuring scalability and reliability.
• Collaborate with cybersecurity and infrastructure teams to implement secure engineering requirements and modernize services.
• Improve telemetry, monitoring, logging, and observability across production systems, and support cloud-based infrastructure.

• We are not looking for a dedicated cybersecurity specialist. Instead, we’re seeking an experienced software engineer who has worked alongside security teams and has experience implementing technical requirements related to security, reliability, and compliance within production systems
• This role is best suited to engineers who enjoy solving technically challenging problems and have experience working on complex systems in industries such as aerospace, scientific computing, telecommunications, biotech, robotics, or other high-reliability environments
• Experience with containers, CI/CD pipelines, and modern software delivery practices
• Comfortable working in Linux-based development environments
• Strong Python development skills
• 5+ years of professional software engineering experience
• Strong backend engineering experience building and maintaining production systems
• Strong understanding of systems engineering, performance, reliability, and operational concerns
• Experience working with AWS-based environments (GCP experience also considered)
• Experience with at least one compiled language such as Rust, C++, Go, Java, or C
• Strong communication and documentation skills
• Experience collaborating with infrastructure and/or cybersecurity teams to implement technical requirements
• Comfortable operating in fast-moving engineering environments
• Experience in smaller engineering organisations where engineers wear multiple hats across development and operations
• Experience building observability or telemetry solutions using tools such as Grafana, Databricks, or Elasticsearch
• Advanced academic research background (PhD/Postdoc) in engineering, physics, computer science, or related scientific disciplines
• Curious and adaptable
• Pragmatic problem-solvers
• Experience with PostgreSQL or other relational databases
• Exposure to secure software development or DevSecOps practices
• Familiarity with GitHub Actions or modern CI/CD tooling
• Collaborative and low-ego
• Experience working in aerospace, scientific computing, biotech, telecommunications, robotics, or other technically complex industries
• Familiarity with Kubernetes, Terraform, and infrastructure-as-code approaches
• Interested in complex systems and infrastructure
• Open to learning new technologies and domains
• This role is primarily backend and platform focused. We are generally looking for engineers with stronger backend and systems experience rather than heavily frontend-focused backgrounds
