Role 

We are looking for an AI Operations Engineer to join our team. This is a hybrid role based in our Zagreb office, reporting to Dominik Jurincic within the Red Teaming department. As an AI Operations Engineer, you will support the AI Red Team by operating and scaling the evaluation infrastructure that powers SPLX’s model benchmarks and MCP server registry. You’ll be the engineering force behind our continuous AI security testing workflows, ensuring our evaluation pipelines run reliably across a rapidly expanding ecosystem of LLMs and agentic tools.

What you’ll do (Role Expectations)

• Operate and extend our LLM benchmarking pipeline by integrating new models — whether through provider APIs or self-hosted deployments on virtualized infrastructure — and executing our security suite to populate and maintain the model benchmarks page
• Kick-off and maintain the SPLX MCP server registry by onboarding open-source MCP servers, provisioning their runtime dependencies, and running our dynamic code scanning and security testing against them
• Build and maintain reproducible deployment environments for evaluating third-party AI systems, ensuring consistent and reliable test conditions across diverse model and tooling configurations
• Partner with Red Team engineers and researchers to streamline evaluation workflows, automate recurring testing operations, and surface insights from benchmark and registry data
• Continuously improve the team’s internal tooling and operational processes, identifying opportunities to reduce manual effort and accelerate the cadence of model and MCP evaluations

Who You Are (Success Profile)

• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. You adapt to what’s needed, navigating seamlessly between high-level strategy and hands-on execution.
• You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
• You are a learner. You have a true growth mindset and never stop developing yourself, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.
• You operate with urgency. You understand that in a high-growth environment, speed and quality are not mutually exclusive. You have a relentless focus on execution and a bias for action, delivering high-impact results quickly to win for the customer and the team.

What We’re Looking for (Minimum Qualifications)

• 1+ years of professional software engineering experience with Python, including the ability to ship reliable, production-quality code in a collaborative environment
• Working familiarity with the modern AI/ML ecosystem, including LLM provider APIs, model deployment patterns, and emerging protocols such as the Model Context Protocol (MCP)
• Hands-on experience with containerization (Docker) and deploying applications across cloud or virtualized infrastructure
• Solid working knowledge of REST APIs and modern integration patterns, including authentication, service orchestration, and debugging across distributed components
• Strong attention to detail and a track record of operating consistently in environments where reproducibility, rigor, and follow-through matter

What Will Make You Stand Out (Preferred Qualifications)

• Prior exposure to LLM evaluation, AI security, or red teaming workflows in a research or applied setting
• Familiarity with the broader open-source AI tooling landscape — including MCP servers, model serving frameworks, or agentic systems — and the curiosity to keep up with a fast-moving space
• Background in DevOps, platform engineering, or infrastructure automation, with comfort building reproducible test environments at scale

Thousands of hotels, resorts, and casinos around the world depend on Duetto’s platform to run their revenue strategy — and you’ll be one of the people making sure it never lets them down. As a Senior DevOps Engineer, you’ll own the infrastructure that powers our global SaaS platform: designing for scale, building for reliability, and driving the kind of security-first culture that keeps us ahead of the curve. If you thrive in complex cloud environments, love solving hard problems, and want your work to have real, tangible impact — this is the role.

What makes us different?

Duetto is the hospitality industry’s leading revenue management platform, founded in 2012 by former Wynn Resorts executives who knew the industry needed better technology. We built the world’s first Revenue & Profit Operating System — a suite of tools (GameChanger, ScoreBoard, BlockBuster, Advance and more) that goes beyond room pricing to give hotels, resorts and casinos a complete picture of their revenue and profitability.

Trusted by clients ranging from independent boutique hotels to global chains, we’ve been named the #1 Revenue Management Software by HotelTechAwards four years running and the #1 Best Place to Work in Hotel Tech in 2025. Backed by GrowthCurve Capital since 2024, we’re accelerating our investment in AI — and we’re genuinely passionate about the industry we serve. We build products we’re proud of, for customers we care about.

What you’ll be doing

• Design and implement robust, scalable AWS infrastructure — supporting key system migrations, platform growth, and the reliability our customers depend on.
• Own the reliability, performance, and security of our production environment: high uptime, rapid incident resolution, and proactive capacity planning.
• Build and maintain CI/CD pipelines, deployment automation, and infrastructure-as-code using Terraform, Terragrunt, and Chef.
• Monitor system health using enterprise observability tools (Prometheus, Grafana, DataDog), defining metrics and response playbooks that get ahead of incidents before they happen.
• Lead security-first practices across the infrastructure estate — proactively addressing vulnerabilities and driving SOC 2 compliance.
• Partner with engineering teams to integrate operational requirements into the development lifecycle and align on architecture decisions.
• Champion AI adoption within DevOps and SRE workflows, evaluating tooling that increases team velocity and reduces toil.
• Respond to on-call incidents with urgency — troubleshoot complex issues, lead detailed root cause analyses, and implement fixes that prevent recurrence.

What we’re looking for

You may be a great fit if you have:

• 5+ years in a DevOps, SRE, or infrastructure engineering role.
• Hands-on AWS experience across IAM, VPC, EC2, ELB, RDS, S3, Lambda, API Gateway, Secrets Manager, KMS, CloudWatch, and CloudTrail — including multi-account management and SSO.
• Proficiency with Terraform for infrastructure-as-code, plus experience with configuration management tools like Chef or Ansible.
• Experience with CI/CD tooling including GitHub, GitHub Actions, JFrog Artifactory, and Jenkins, with familiarity with GitOps methodologies.
• Strong working knowledge of enterprise monitoring platforms — Prometheus, Grafana, or DataDog.
• Solid troubleshooting skills and a track record of leading root cause analyses and implementing durable fixes.
• Proficiency reading Java, Ruby, Bash/Zsh, HCL, Python, and JavaScript.
• Experience with SOC 2 compliance and security-first infrastructure practices.
• Comfort with a weekly on-call rotation.

Strong candidates may also have:

• Experience with container and orchestration technologies — Docker, ECS, or EKS.
• Experience migrating workloads from on-prem or colocation environments to AWS.
• Familiarity with Windows Server, SQL Server, IIS, and .NET environments.
• Experience administering and synchronising MongoDB replica sets.
• Knowledge of ISO 27001, Layer 7 load balancing, or Terragrunt.
• Background in hospitality technology.
• A degree in Computer Science or a related field — or equivalent experience.

Why Duetto?

• Infrastructure that matters — your work directly underpins a platform that hotel operators around the world rely on every day. The stakes are real, and so is the satisfaction.
• AI is how we work — we’re not just talking about AI adoption; we’re actively investing in it across every function, including DevOps. You’ll have space to evaluate and implement tooling that makes a genuine difference.
• A team that moves fast — you’ll report into the Senior DevOps Manager and work alongside engineers who are serious about craft, reliability, and continuous improvement.
• Growth with purpose — backed by GrowthCurve Capital, we’re scaling our platform and our team. There’s a lot being built here, and senior engineers have real influence over how it’s done.
• Come as you are — we’re a diverse, distributed team that values different perspectives and builds inclusively.
