Platform Engineer - Kubernetes (Go)

Ansys; Sevilla; Presencial; EUR 60.000 - 90.000; Jornada completa

Descripción de la vacante

Ansys in Sevilla is hiring a Platform Engineer to help build our sovereign cloud security stack. You will design and implement the Key Management Service, envelope encryption, and cryptographic workflows that the platform relies on.

You’ll own building Kubernetes Operators, APIs for other teams, and operate the system with a strong emphasis on security and reliability. English proficiency required for international collaboration.

Formación

• Real experience building software in Go, with Kubernetes as a core part of your day-to-day.
• Solid knowledge of applied cryptography: symmetric and asymmetric encryption, key management, digital signatures.
• Experience in cybersecurity, cloud platforms, or platform/infrastructure teams that work with these concepts daily.
• You care about security as a core design principle, not just a checkbox.
• High level of English for international collaboration.

Responsabilidades

• Build the Key Management Service (KMS) and envelope encryption flows across the platform.
• Develop Kubernetes Operators to automate the system's lifecycle with no manual intervention.
• Create APIs for teams to request keys, sign documents, or verify signatures without cryptography expertise.
• Operate and own the security-critical infrastructure under a you-build-it, you-run-it model.
• Collaborate with international counterparts to ensure security standards are met.

Descripción del empleo

One of the largest retail companies in Europe is building its own sovereign cloud from the ground up - infrastructure designed so that the business's critical data and services live within the European Union, fully independent of the major US or Asian providers.

Within that platform there's a team that doesn't build customer-facing features, but something far more fundamental: the system that protects, encrypts, and manages every key and secret the rest of the platform depends on. Without this team, nothing else can be considered secure. We're looking for the person who will join that team as a Platform Engineer.

What you'll build:

• The Key Management Service (KMS) : the central system that generates, rotates, and protects encryption keys across the entire platform.


• Envelope Encryption flows (multi-layer encryption), managing the relationship between data keys and master keys.


• Kubernetes Operators that fully automate this system's lifecycle - with no manual intervention.


• APIs that other teams across the company will use to request keys, sign documents, or verify signatures, without needing to understand cryptography themselves.


• A product that must meet the industry's toughest security standards (AES, RSA, ECDSA, HMAC) and the audit requirements of a high-risk cloud environment.

You'll work under a "you build it, you run it" model: what you design, you operate. No launching it and walking away.

What we're looking for

• Real experience building software in Go , with Kubernetes as a core part of your day-to-day - not just deploying on it, but building Operators .


• Solid knowledge of applied cryptography : symmetric and asymmetric encryption, key management, digital signatures.


• Ideally, you come from a cybersecurity company, a cloud provider, or a platform/infrastructure team that already works with these concepts daily.


• You care about security not as a checkbox, but as the core of what you build.


• High level of English - the team works with international counterparts.

Why this project

You'll build critical infrastructure with a high degree of technical autonomy: the team operates independently in order to sign off on security for the rest of the platform. You'll be part of one of the largest infrastructure projects currently being built in Europe, with strong team growth plans over the coming months. You'll work on real engineering problems, not business features - the kind of work few retail companies offer in-house.
