Job description

What we are building

Mimica is an AI-powered process intelligence platform enabling enterprises and individuals to reclaim their most precious resource: time. We've all seen repetitive tasks and redundant processes quietly drain productivity and creativity. Not because companies don’t want to become more efficient, but because they don’t know where to start. Mimica automatically analyzes your team's work, then generates the AI agents to execute it. Our software turns everyday work into data-backed decisions, helping companies remove process bottlenecks, automate the right tasks, and upskill teams with precision and confidence. We’ve raised $26 million in Series B financing and are scaling fast. Backed by investors including Khosla Ventures and Paladin Capital, our proprietary AI technology is trusted by Fortune 500 companies to accelerate transformation. Mimica is recognized as a Top 100 AI Start-up by Accel and an industry Leader by the Everest Group.

Our team

Behind our platform is a team of exceptionally talented people, remote-first and globally distributed across 16+ countries. We're looking for curious, collaborative people excited to solve complex problems. You'll join a fast-paced environment built on high ownership, bottom-up thinking, and transparent, open communication – helping some of the world's leading organizations transform the way work gets done with AI.

Your mission

Mimica is growing fast, and so is the demand on our Platform Team. As Head of Platform, you will lead a lean but highly capable team that is the backbone of every engineering squad in the company, and you will own the infrastructure strategy, including all AI infrastructure, as we scale. The Platform team services the entire engineering organisation: keeping environments healthy, unblocking teams, building the infrastructure that lets everyone else move faster, and working with teams regarding SRE topics and developer experience too. As you work with us, the role will develop into designing Mimica's infrastructure strategy at scale. The team has 4 engineers today, around 6 by the end of the year, and 10+ in 2027, so the role has the potential to grow into a "manager of managers" level as the company grows. This is a role with real scope: expanding to multi-region and physically separated database environments, supporting Mimica’s first installable infrastructure component for enterprise, and owning FinOps. One day you are defining the standard menu of deployment options for enterprise customers, the next you are in a security review or an architecture decision on AI infrastructure. We are looking for leaders with either an application development or a systems/infrastructure background. What matters more than your origin story is your hands‑on credibility with Kubernetes, IaC, and cloud platforms, your ability to lead engineers and other leaders, and your ability to collaborate closely with Product, ML, Security, Sales and Customer Success. If you want to work in a place where your contributions are visible, your scope is broad, and the problems are real, this is the role for you.

Part of your day-to-day

• Own Mimica's infrastructure strategy and the platform roadmap across all products, with the final call on cloud architecture, deployment models, infra vendors and platform standards.
• Lead and grow the Platform team: Manage existing Platform and SREs, plan headcount, set goals and metrics, and design the sub-team split (Cloud & Developer Platform, Reliability & SRE, AI Infrastructure) as the team grows.
• Own all AI infrastructure, including training and serving infra, MLOps tooling, Vertex and model access.
• Maintain Mimica’s DevEx culture - improve agency for product teams without compromising on compliance, create paved roads for deployments, and identify pain points as they arise.
• Own the infra and LLM budget, forecast and unit economics, including cost attribution by product and customer and the GCP relationship.
• Own reliability across engineering: SLOs, on-call model, incident process, postmortems, DR testing and capacity planning.
• Own the CI/CD and developer platform, infrastructure-as-code (Terraform, ArgoCD, Crossplane) and observability standards (Honeycomb, Grafana, Loki).
• Work with the Platform PM, your peer, to define client needs and turn them into the platform roadmap.
• Act as the named technical owner for infrastructure in enterprise deals and security reviews, joining high-stakes sales and client calls and coaching your team to take the rest.
• Guide the craft mentors for infrastructure, MLOps and Python engineering, and set engineering-wide standards for reliability, on-call, CI/CD and craft.
• Report monthly platform health and costs to leadership, and lead the infrastructure part of technical due diligence.

Requirements

• Proven experience leading engineers, ideally including managing a team lead or other managers, and growing a team through hiring and sub-team design.
• Solid hands‑on experience with Kubernetes, whether on GKE (preferred), EKS, OnPrem, or another managed Kubernetes service, across multiple regions.
• Proven experience with infrastructure-as-code as a core part of your platform, such as Terraform, and with ArgoCD or a comparable GitOps tool.
• A track record in owning reliability: setting SLOs and SLAs, running on-call, leading incident response and postmortems, and testing disaster recovery.
• Observability experience with at least one major platform: Honeycomb, Datadog, Grafana, or New Relic.
• Comfortable with code, and able to review architecture and prototypes hands‑on.
• Experience owning an infrastructure budget, including cloud cost attribution, forecasting and cloud-provider relationships.
• Experience designing deployment models for enterprise customers (single tenant, regional, data residency) and supporting security reviews and contracted SLAs.
• Background in startups or scale-ups: you are used to ambiguity, moving fast, and wearing multiple hats.
• Strong communication and collaboration skills: you can translate infrastructure complexity into clear language for engineers, executives and clients, and you know when to say no to bespoke requests.

Bonus / Nice to have

• Familiarity with Crossplane, or a similar product like Config Connector.
• Experience with Temporal for workflow orchestration.
• Security and compliance experience, particularly supporting SOC 2.
• Experience supporting a funding round, including technical due diligence.

What we offer

• Generous compensation + stock options - aligned with our internal framework, market data, and individual skills.
• Distributed work: Work from anywhere - fully remote, in our hubs, or a mix.
• Company-issued laptop, remote setup stipend, and co-working budget
• Flexible schedules and location
• Ample paid time off, in addition to local public holidays
• Enhanced parental leave
• Health & retirement benefits
• Annual learning & development budget
• Annual workaways and regular virtual & in-person socials
• Opportunity to contribute to groundbreaking projects that shape the future of work
