Department/Project Description

People
USA: Client’s base location, including top management, R&D, several manufacturing facilities, and testing labs.

Ukraine / Poland: GlobalLogic management (project, release, architecture) and 4 Scrum teams with full competencies: Business Analysis, Development, and Testing. Additional teams include Performance Testing, Test Automation, L3 Support, and Design. The Lviv office hosts a large hardware lab. The GlobalLogic team counts 100+ specialists and continues to grow.

Product
We develop a POS solution that enables both attended (employee) and unattended (customer) tunnel car wash services.

There are two hardware labs supporting the U.S. and Canadian markets: Ohio, USA and Lviv, Ukraine. A single hardware set includes multiple points of sale, various sensors, readers, cameras, payment terminals, servers, and automatic gates. The Ukrainian team develops a PWA and a hybrid web application (.NET & Angular) that runs on both hardware and cloud, covering the complete customer flow: from account creation to recognition to sale and car guidance through the tunnel. All embedded development is handled by the client’s team in the USA.

GL Scrum teams have hardware dependencies based on the functional areas they support, therefore on-site presence in the Lviv office is required.

General Project QA structure
Each Scrum team has its own Manual QA Lead and several Manual QA Engineers, typically 2-3 per team with varying levels of seniority. Across GlobalLogic teams, there are 11 Manual QA, 6 Automation QA, and 5 Performance Engineers, all managed by a single Quality Manager.

On the customer side, there is a QA Director overseeing all of the client’s products - both those developed by GlobalLogic and those handled internally - supported by a pool of 10 Manual QA Engineers. Collaboration between GlobalLogic and U.S.-based QA teams is frequent and closely aligned.

About Us

Cikumas GmbH, based in Kilchberg (Canton of Zurich, Switzerland), builds ClassOwl — an all-in-one school-management platform that replaces the patchwork of disconnected tools most schools run on today. Instead of re-entering the same student data into five or six separate systems (admissions, gradebook, invoicing, timetabling, government reporting), ClassOwl combines a Student Information System (SIS), Learning Management System (LMS) and Enterprise Resource Planning (ERP) into one white-label platform, tailored to each school's own processes and branded as their own.
 

Who we’re looking for
We are hiring a Sales Development Representative (SDR) to reach out to schools by phone and open the door to a conversation. Your job is not to sell — it's to generate enough interest in what ClassOwl can do for a school (save staff time, eliminate duplicate data entry, replace multiple disconnected tools) that they agree to a meeting. This role is currently outsourced to an external agency; we're bringing it in-house.
 

Responsibilities

• make outbound calls to schools using Aircall
• follow up persistently on leads in our school database (currently an Excel-based CRM)
• book confirmed appointments directly into the sales calendar, organized by canton for efficient travel planning
• develop and refine an effective call script
   

What we expect

• comfort with outbound cold calling and persistent follow-up
• fluent  German/Italian/French ( at least one of above)
• ability to work independently and consistently hit call and booking targets
• calls per day (typical range: 50–130)
• Appointments with schools booked as a final result 
   

Benefits

• part-time arrangements accepted
• we offer two cooperation formats to choose from — ФОП (standard) and ФОП+ (an extended package with paid vacation, bonuses, and additional compensations); details of each format are discussed during the interview
• flexible schedule and a fully remote team — work from wherever suits you, as long as you can call during school hours in the relevant time zone
• budget for learning and professional development

Help scale the infrastructure behind a real-time iGaming platform serving 150M+ players worldwide while leading our SRE and Platform Engineering teams.

About Patrianna

At Patrianna, we build a high-performance B2B platform for the global iGaming industry, enabling partners to launch and scale digital gaming products across multiple international markets. Our platform serves as the foundation for multiple gaming brands, providing the core systems that power gameplay, integrations, and platform capabilities across different markets.

We operate in a fast-moving scale-up environment where impact matters more than process for its own sake. Teams are trusted to take ownership of the systems they build and the outcomes they deliver.

Our engineering culture is built around a few core principles:

• Pragmatic execution: We focus on solving meaningful engineering problems and delivering reliable systems without unnecessary bureaucracy;
• Clear ownership and accountability: Teams operate within defined responsibilities and leadership structures that ensure decisions are made and outcomes are delivered;
• Technical depth matters: We value engineers and managers who understand their systems deeply and make thoughtful technical decisions;
• Direct communication: We address problems openly, challenge assumptions, and resolve issues quickly.

We believe strong engineering leadership starts with technical credibility and ownership of outcomes.

AI-Driven Engineering Culture

We are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software — not an experiment, not a trend, and not an optional add-on.
AI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential—AI amplifies our engineers, it doesn’t replace responsibility for technical decisions.

The role

We are looking for a hands-on Engineering Manager to lead our DevOps function across two specialized engineering teams: Site Reliability Engineering (SRE) and Platform Engineering.

The SRE team is focused on production reliability, availability, observability, incident management, operational excellence, and continuously improving the resilience of our systems.

The Platform Engineering team works on larger strategic initiatives that evolve our infrastructure and engineering platform — improving scalability, automation, developer experience, deployment capabilities, infrastructure architecture, and operational efficiency.

You will be responsible for ensuring both teams have clear roadmaps, well-defined priorities, realistic commitments, and strong execution. You will create the structure and engineering practices necessary for teams to deliver complex infrastructure initiatives predictably while maintaining the reliability of a rapidly growing production platform.

This is not a coordination-only management role.

We expect our DevOps Engineering Manager to have deep technical expertise and remain close to the technology. You should be capable of understanding infrastructure architecture in depth, challenging technical decisions, reviewing proposed solutions, troubleshooting complex production problems, and working hands-on with the platform when necessary.

You will combine the technical depth of a senior DevOps/Platform engineer with strong engineering and operational management, delivery, and people leadership skills.

What you will be doing

Management & Delivery:

• Own the DevOps roadmap and delivery outcomes – establish clear roadmaps across SRE and Platform Engineering, translate priorities into concrete initiatives and commitments, and ensure teams deliver against realistic timelines;
• Drive predictable execution – establish effective planning and execution practices, track progress against commitments, identify delivery risks early, manage dependencies, and ensure clear ownership of initiatives;
• Lead SRE and Platform Engineering – provide leadership across both operational reliability and longer-term platform development, balancing immediate production needs with strategic infrastructure improvements;
• Own people management – manage and develop DevOps engineers, including performance reviews, career development, compensation and promotion input, hiring, team structure, and handling performance concerns when needed;
• Partner with engineering teams – work closely with Engineering Managers, Team Leads, and engineers across the organization to understand infrastructure needs, resolve systemic problems, and ensure the platform enables rather than blocks product delivery.

Technical Leadership:

• Provide hands-on technical leadership – stay close to infrastructure and production systems, participate in architecture discussions, challenge technical decisions, review proposed solutions, and contribute directly when complex problems require it;
• Drive platform reliability – continuously improve availability, resilience, observability, incident response, capacity management, and operational readiness across the platform;
• Strengthen incident management – ensure incidents are handled effectively, root causes are understood, postmortems produce meaningful actions, and recurring operational problems are systematically eliminated;
• Evolve the engineering platform – drive initiatives around Kubernetes, cloud infrastructure, CI/CD, GitOps, Infrastructure as Code, observability, scalability, security, and developer experience;
• Improve engineering effectiveness – identify bottlenecks, repetitive operational work, and inefficient processes, and drive automation and platform improvements that increase engineering productivity;
• Drive infrastructure efficiency – continuously evaluate infrastructure architecture, resource utilization, and cloud costs, identifying opportunities to improve performance and reliability while keeping the platform cost-efficient.

What we are looking for

Leadership & Management Requirements:

• Engineering leadership experience – proven experience leading infrastructure, DevOps, SRE, or Platform Engineering teams while balancing technical leadership, delivery ownership, and people management;
• Strong delivery ownership – ability to build realistic roadmaps, break complex technical initiatives into executable work, establish commitments and deadlines, identify risks, and drive initiatives through to completion;
• Strong communication skills – able to communicate clearly with engineers and leadership, challenge assumptions constructively, explain technical trade-offs, and create alignment around priorities and decisions.

Technical Requirements:

• Deep hands-on DevOps expertise – extensive experience building and operating production infrastructure, with the technical depth expected from a Senior/Lead/Staff-level DevOps, SRE, or Platform Engineer;
• Strong Google Cloud Platform experience – deep production experience with GCP, including GKE, Compute Engine, networking, IAM, DNS, load balancing, and cloud cost optimization;
• Deep Kubernetes expertise – strong understanding of Kubernetes architecture, networking, ingress, storage, autoscaling, security, cluster lifecycle, and production troubleshooting;
• Infrastructure as Code expertise – strong production experience with Terraform/Terragrunt, Helm, and infrastructure automation;
• CI/CD and GitOps expertise – strong experience designing and operating modern delivery platforms using technologies such as Argo CD, GitHub Actions, Jenkins, or Azure DevOps;
• Strong production operations background – experience operating high-availability production environments, participating in on-call rotations, troubleshooting distributed systems, and leading incident response;
• Observability expertise – strong understanding of metrics, logs, tracing, alerting, SLOs, and production monitoring using technologies such as Prometheus, Grafana, Loki/ELK, or similar platforms;
• Strong systems thinking – ability to reason about complex distributed systems, understand dependencies and failure modes, and make pragmatic architectural trade-offs across reliability, scalability, delivery speed, and cost.

Nice to Have

• Experience leading both SRE and Platform Engineering teams;
• Experience operating high-load, real-time distributed platforms;
• Experience defining and operating SLOs, SLIs, and error budgets;
• Experience building internal developer platforms or developer self-service capabilities;
• Experience with Kafka and large-scale event-driven systems;
• Experience with PostgreSQL/AlloyDB and Redis;
• Experience driving cloud infrastructure cost optimization / FinOps initiatives;
• Experience in iGaming;
• Experience working in product companies or fast-growing scale-ups;
• Previous experience as a Staff/Principal DevOps Engineer, SRE, Platform Engineer, or Infrastructure Architect.

• AI agent development: Build text and voice agents for customer support, with seamless conversation handoffs to human support agents.
• New sales channels: Enable sales through AI channels, including apps in ChatGPT and Claude, and develop APIs and MCP integrations for third-party agents.
• Knowledge and integrations: Build RAG solutions using internal knowledge and integrate them with the BusSystem API, Zoho Desk, n8n, and other internal services.
• Department automation: Build automated workflows for teams across the company.
• Optimization and quality: Monitor response quality and cost, set up evaluations (evals), and optimize latency.
• Knowledge sharing: Run one workshop per month and help internal “AI guides” with complex automations.

Requirements:

• Software development experience: 2+ years of commercial experience with Python or TypeScript.
• AI stack and architecture: Hands-on experience building AI agents using tool use, structured outputs, and MCP. Experience gained through personal projects also counts.
• Modern development tools: Regular use of AI-assisted development tools such as Claude Code, Cursor, or similar solutions.
• Engineering mindset: Ability to investigate and address hallucinations and agent failures. You find debugging these issues engaging rather than intimidating.

Nice to have:

• Experience deploying AI solutions to production and understanding real-world use cases and failures.
• Experience with voice agents (Voice AI) and evaluations (evals).
• Experience in travel or e-commerce.

What We Offer:

• A competitive compensation based on the interview results, plus a bonus for each successful launch with a verified business impact, measured by comparing results before and after launch.
• Work format: fully remote work from any country, preferably in a European time zone within two hours of Kyiv; a five-day working week with two days off and a flexible start time.
• Tools and professional development:
  • Company-funded access to all necessary AI tools and services on business plans;
  • A separate monthly budget for testing new models and APIs;
  • A budget for relevant training, courses, and conferences.
• Culture: An experiment that is measured and stopped at the right time is a valid outcome. Your launch is your case study, which you can present under your own name without disclosing customer data.
• Team: Direct reporting to the MD of infobus.eu (AI Transformation Lead) and close collaboration with an AI Project Manager.
