Job summary

Mimica, an AI-powered process intelligence platform, seeks a DevOps / Platform Engineer to join our remote-first engineering team. You will help keep environments healthy, unblock teams, and build infrastructure that lets everyone move faster across Kubernetes, IaC, and cloud platforms.

You’ll contribute to multi-region deployments, BYOC, Terraform to Crossplane migration, FinOps, and robust observability with Honeycomb and Grafana. This is a high-ownership role in a fast-growing startup.

Qualifications

• Hands-on experience with Kubernetes on GKE, EKS, or other managed services.
• Terraform as the primary IaC tool; Terragrunt is a plus.
• IAM and identity management on GCP or AWS.
• Experience with ArgoCD or equivalent GitOps tool.
• Observability tooling: Honeycomb, Grafana, Datadog, or New Relic.
• Proficiency in Python for automation and tooling.
• Background in startups or scale-ups; comfortable with ambiguity.
• Strong communication and collaboration, translating infra to engineers.
• Experience leading or participating in incident responses.

Responsibilities

• Support engineering teams in developing mature, resilient apps on GKE, providing guidance and unblockings.
• Develop and maintain infrastructure-as-code using Terraform and ArgoCD; work on Python platform apps.
• Manage GKE environments across multiple regions; handle IAM and identity management.
• Investigate, triage, and resolve issues; monitor health of databases and components.
• Participate in on-call rotation to ensure platform availability and incident handling.
• Contribute to migrating IaC from Terraform to Crossplane; expand multi-region/clustering.
• Drive FinOps to gain visibility and control over multi-account cloud spend.
• Design access patterns for BYOC and single-tenancy environments; simplify multi-environment navigation.

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 a DevOps / Platform Engineer, you will join a lean but highly capable team that is the backbone of every engineering squad in the company.

We service the entire engineering organisation: keeping environments healthy, unblocking teams, and building the infrastructure that lets everyone else move faster. We’re looking to increase our capacity as demand for our services is growing fast.

On top of the day-to-day demand from other teams, we are taking on some of our most ambitious infrastructure projects yet: expanding to multi-region and single-tenancy environments, supporting BYOC (Bring Your Own Cloud) deployments, migrating our IaC from Terraform to Crossplane, and getting serious about FinOps. This means the work is varied: one day you are debugging an RBAC issue in production, the next you are designing a multi-cloud access pattern from scratch.

We are looking for engineers with either an application development or a systems/infrastructure background.

What matters more than your origin story is your hands-on comfort with Kubernetes, IaC, and cloud platforms, your curiosity, and your ability to collaborate closely with other engineering teams. 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

• Support engineering teams across Mimica in developing mature, resilient applications running on GKE, advising on best practices and unblocking issues quickly.

• Develop and maintain infrastructure-as-code using Terraform and ArgoCD, as well as Mimica-specific Platform applications written in Python.

• Manage and maintain GKE environments across multiple regions (EKS experience is also acceptable), including IAM and identity management on GCP (AWS acceptable).

• Investigate and triage issues in existing applications, observe database and system component health, and implement changes to support the SDLC of other teams.

• Participate in a scheduled on-call rotation to monitor system health, respond to incidents, and ensure high platform availability.

• Contribute to migrating our IaC layer from Terraform to Crossplane and support expansion into multi-region clusters and single-tenancy environments.

• Drive FinOps initiatives, helping us get visibility into and control over cloud spend across multiple accounts and environments.

• Help design and implement access patterns for new BYOC and single-tenancy environments, making it seamless for engineers to navigate an increasingly complex multi-environment landscape.

• Instrument, monitor, and improve observability across our stack using tools such as Honeycomb and Grafana.

Requirements / What we're looking for

• Solid hands-on experience with Kubernetes, whether on GKE (preferred), EKS, OnPrem, or another managed Kubernetes service. You know your way around cluster configuration, scheduling, RBAC, and debugging live issues.

• Proven experience with Terraform as your primary IaC tool. Familiarity with Terragrunt is a plus.

• IAM and identity management experience on at least one major hyperscaler: GCP (preferred) or AWS.

• Experience with ArgoCD or a comparable GitOps tool for continuous delivery.

• Observability experience with at least one major platform: Honeycomb, Datadog, Grafana, or New Relic. You know how to set up meaningful dashboards, alerts, and traces.

• Comfortable writing code, particularly Python, to automate platform tasks and build internal tooling.

• 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 application engineers, and you know when to raise a flag versus just fixing it.

• Experience leading and participating in incident responses. You systematically decompose problems and know how to get to the root cause without panicking.

Bonus / Nice to have

• Experience running GPU workloads on Kubernetes, particularly in the context of ML infrastructure.

• Familiarity with Crossplane (or strong interest in migrating to it from Terraform).

• Experience with Temporal for workflow orchestration.

• Hands-on knowledge of Grafana Alloy, Loki, or similar observability tooling in the Grafana ecosystem.

• Experience with MongoDB, PostgreSQL, or SQL Server.

• Security engineering experience, particularly around hardening Kubernetes environments or supporting compliance initiatives (e.g. SOC 2).

Hiring process

Our process is designed to be practical and respectful of your time. We want to see how you think, not just what you know.

1. Recruiter Screen (30–45 min) - A conversation with our Talent Partner to explore your background, motivations, and culture fit.

2. Live Technical Challenge: Triage & Debug (1 h) - A hands-on live challenge with the Hiring Manager and a member of the team.

3. System Design Interview (1h) - A live session focused on infrastructure design: we will walk through a real architectural problem and discuss trade-offs.

4. Behavioural Interview (60 min) - A deeper conversation with the Engineering Manager for Platform and our Co-founder & CTO.
