Arcesium; Lisboa; On-site; EUR 21,000 - 32,000; Full time

Job summary

Arcesium is seeking an entry-level IT & infrastructure engineer for our Lisbon office. You will be the local IT point of contact, handling onboarding, hardware provisioning, and day-to-day support, while also tackling automation tasks and CI/CD work alongside senior engineers.

You'll learn Linux, AWS, and scripting, growing from hands-on IT to owning small pieces of infrastructure over time. Strong English is required; Portuguese is a plus.

Qualifications

• 0-2 years in IT support, systems administration, or junior engineering role (internships and academic projects count).
• Linux fundamentals: comfortable in a Linux/Unix environment - command line, file permissions, basic networking, and troubleshooting common issues.
• Scripting: Working knowledge of at least one scripting language (Python, Bash, or similar) and eagerness to write more of it.
• IT support mindset: Comfortable being hands-on with hardware and being the local face of IT - patient, clear communicator, good with people who aren't technical.
• Cloud curiosity: Basic familiarity with a cloud platform (AWS preferred) and genuine interest in learning infrastructure and automation - formal production experience not required.
• Ownership and reliability: Able to work independently as the only (or one of very few) on-site technical resource, while staying closely connected to a distributed, remote-first team.
• Language: Fluent English (written and spoken); Portuguese is a plus for local vendor and office coordination.
• Education: Bachelor's degree in Computer Science, Engineering, IT, or related field; equivalent practical experience considered.

Responsibilities

• Be the local IT point of contact for the Lisbon office - onboarding, hardware, and everyday support.
• Learn and apply core SRE practices - scripting, CI/CD, and cloud infrastructure - under the guidance of senior engineers.
• Split your time between hands-on specialist work and hands-on engineering work; grow into more of the latter over time.
• Build a foundation in Linux, AWS, and automation that sets up a long-term engineering career path.
• Document and communicate clearly: keep records of issues and fixes for recurring problems and share blockers with the wider team.
