Role overview

The Senior Software Development Engineer is a key contributor within Indra’s UTM Product team, responsible for the design, development, and delivery of high-quality software components within GuardianUTM and related systems.

GuardianUTM is continuing to evolve as a platform, with a strong immediate focus on enhancing reliability, performance, and operational maturity alongside the delivery of new capabilities. This role requires an engineer who is comfortable working within a growing and evolving system, able to identify areas for improvement, take ownership, and drive outcomes with minimal direction.

The successful candidate will be a self-starter—motivated, proactive, and delivery-focused—capable of navigating ambiguity and getting things done. Alongside strong hands-on engineering capability, they will take ownership of significant features or services and contribute to building a robust, scalable, and secure platform.

Working closely with Product, Architecture, and Engineering leadership, the Senior Software Development Engineer ensures that product requirements are translated into effective technical implementations aligned with architectural direction and regulatory constraints.

The role also contributes to strengthening engineering practices, improving system resilience, and supporting overall platform growth.
