Jobs

We are building the infrastructure that powers restaurant ordering, real-time WebSockets, and multi-tenant CDN delivery for thousands of users across Eastern Europe. Our platform runs on AWS EKS with Karpenter-managed node pools, served through CloudFront edge, and backed by MySQL RDS, Redis, and SQS — all provisioned through Terraform across three environments (dev / staging / prod).

We are looking for a DevOps Engineer who takes ownership of production systems and builds things that last. Not someone who runs commands — someone who designs the pipeline, writes the module, monitors the result, and fixes the alert at 10PM if needed.

This role owns the Kubernetes platform at the cluster level — you will administer node pools, manage upgrades, design topology changes, and support engineering teams deploying PHP/Laravel and Next.js workloads daily.

What you'll do

Infrastructure

• Manage and evolve AWS infrastructure using Terraform — modules, multi-region, Terraform Cloud remote state across workspaces
• Operate and tune Karpenter NodePools (spot + on-demand) for workload-specific isolation: backend, queue, transaction, websocket, and more

• Own EKS cluster lifecycle — version upgrades, node group migrations (currently AL2 → AL2023), IRSA, Velero backups

   

CI/CD

• Maintain Jenkins pipelines (EC2-hosted, x86 + ARM64 agents) with Groovy shared libraries
• Enforce security gates: Trivy container scanning, Hadolint Dockerfile linting, SonarQube quality checks

• Manage multi-arch Docker builds and ECR repositories per service

   

Observability

• Operate the ELK stack — Filebeat, Metricbeat, Elasticsearch, Kibana
• Maintain Grafana dashboards, Elastic APM, Pyroscope continuous profiling, and OpenTelemetry collector

• Tune CloudWatch alarms and Falco runtime threat detection

   

Security & Edge

• Manage CloudFront distributions with WAFv2 — IP allowlists, geo-blocking, rate limiting, origin header verification
• Administer secrets via AWS Secrets Manager + External Secrets Operator

• Maintain WireGuard VPN and network-level access controls

   

What we're looking for

Required

• 3+ years of hands-on DevOps or platform engineering in production
• Terraform at team scale: modules, remote state, peer review, deployed to production — not just local experiments
• AWS: EKS, VPC, CloudFront, WAF, RDS, ALB, IAM, Secrets Manager, SQS, S3 — at depth, not surface level
• Kubernetes: cluster-level thinking — RBAC, ingress, PodDisruptionBudgets, node group management, helm charts, troubleshooting OOMKills and failed rollouts
• Jenkins or equivalent CI/CD tool with real pipeline ownership
• Python or Bash scripting for automation

Nice to have

• Karpenter (NodePool / EC2NodeClass design)
• ELK stack operations (Filebeat, Metricbeat, Elasticsearch index lifecycle)
• Velero, AWS Backup, disaster recovery playbooks
• Falco or similar runtime security tooling
• Experience deploying PHP/Laravel and Next.js workloads in containers
• Maxwell CDC, RDS Proxy, or Redis operations experience

N-iX is looking for Cloud Infrastructure Engineer to join the team

Client Overview
Our client is a global provider of technology-enabled claims management and repair-network services for leading insurers and automotive partners. They operate a large, distributed technology function supporting business and clients across multiple regions worldwide.

Project Description 

The client's Global Server Support team maintains and operates the Microsoft 365 and Azure cloud platforms that underpin the organisation's infrastructure across multiple regions. Following the departure of a senior team member, we're looking for a Cloud Infrastructure Engineer to plug a capacity gap and keep critical workplace and platform services running smoothly through to year-end. The team grew out of on-premises Microsoft computing and has evolved into a combined Azure platform engineering and modern workplace capability, so the role blends both areas rather than being a pure platform-engineering or pure modern-workplace position.

Role Description 

We're looking for a competent, self-sufficient Cloud Infrastructure Engineer to support the Global Server Support team across both the Modern Workplace (M365) and Azure cloud infrastructure estates. The role is hands-on and delivery-focused — picking up work with minimal supervision and taking routine load off the existing team. 

Responsibilities:

• Provide day-to-day operational support across Microsoft 365 and Azure, acting as an escalation point for incidents raised through the Global Service Desk in an ITIL-aligned environment. 
• Work across the full M365 / Modern Workplace stack — Exchange Online, Entra ID and Conditional Access, security and compliance tooling — keeping the environment stable and secure. 
• Support the Azure cloud infrastructure that underpins the development and DevOps work streams (the team does not own network infrastructure and does not perform DevOps itself). Take routine and assigned workplace and platform tasks off the existing team to free up their capacity for higher-priority work. 
• Contribute to problem management and root-cause analysis to deliver lasting fixes, not just quick restores. 
• Monitor capacity, performance, and availability of cloud services, supporting proactive issue detection across the global estate.
• Maintain security compliance across Microsoft cloud services, applying remediations and changes without business disruption. 
• Support scheduled maintenance — patching, upgrades, certificate renewals, and lifecycle management of cloud resources.

Requirements:

• 3+ years of hands-on experience in cloud infrastructure
• Strong Microsoft background, ideally having progressed from an on-premises infrastructure route into cloud — this foundation matters more than ticking every individual box
• Solid, hands-on M365 / Modern Workplace experience across the platform; the workplace side is where the team most needs support.
• Working knowledge of Azure cloud infrastructure — administration, governance (RBAC, PIM, policy, subscription structure), monitoring, and maintenance.
• Proficiency in PowerShell and Azure Automation for routine operational tasks.
• Experience with Microsoft 365 and Azure security hardening, patching, certificate and lifecycle management across a global estate.
• Comfortable within ITIL-aligned processes (incident, problem, change, request fulfilment).
• Self-driven, organised, and effective working remotely, able to manage priorities and operate with minimal supervision.
• Excellent written and verbal English, able to convey technical concepts to technical and non-technical audiences.
• Experience working within large, complex, distributed organisations across multiple regions and time zones.

Nice to have 

• Microsoft Purview (DLP, retention, eDiscovery) and Power Platform governance.
• Cloud networking awareness (VNets, NSGs, firewalls, private endpoints, routing).
• Infrastructure as Code (Terraform, Bicep, ARM) — useful, though the role is not IaC-heavy.
• Cloud observability tooling (Azure Monitor, Log Analytics, Grafana) and SRE / reliability principles.
• Microsoft certifications (e.g. Azure Administrator Associate).

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
• Education reimbursement
• Memorable anniversary presents
• Corporate events and team buildings
• Other location-specific benefits

*not applicable for freelancers

• Proven track record of scaling teams and driving revenue
• Strong knowledge of operators, aggregators, and providers

Nice to Have

About the Project
We are looking for a Senior Data Scientist / ML Engineer to support a Berlin-based logistics technology product company on a data science project focused on building a production-ready MVP.
The project is currently in an early research / proof-of-concept stage. Initial validation has shown that the concept is technically feasible, and the next step is to bring it from research into a usable MVP that can be integrated into the existing product infrastructure.
The solution will use positional / location-based data to identify specific locations and generate insights that help drivers and improve operational efficiency.
This is not a fully isolated greenfield project. The work will be connected to existing internal systems, data pipelines, and infrastructure.

• Prepare the model and pipelines to run in production on a scheduled basis.
• Work with internal data, product, and engineering teams to understand available data, infrastructure, constraints, and business requirements.
• Translate high-level product and business goals into technical implementation steps.
• Make technical decisions independently while keeping internal stakeholders aligned.
• Document the solution, assumptions, limitations, and handover materials for the internal team.
• Ensure that the MVP can be further scaled, improved, and integrated into the company’s existing product suite.

Required Experience

• 5+ years of experience in Data Science, Machine Learning, or ML Engineering.
• Strong hands-on experience building ML models from concept to production or MVP stage.
• Experience working with ETL processes, data pipelines, data preparation, and model input pipelines.
• Strong Python experience and common data science / ML libraries.
• Experience working with large datasets and imperfect real-world data.
• Ability to work with positional, geospatial, mobility, logistics, or location-based data.
• Experience deploying or preparing ML models for production usage.
• Strong understanding of model evaluation, iteration, and practical trade-offs between accuracy, speed, and business value.
• Ability to work independently with limited day-to-day guidance.
• Strong ownership mindset: ability to clarify requirements, identify blockers, communicate with stakeholders, and drive the work forward.

Nice to Have

• Experience in logistics, transportation, mobility, route optimization, delivery, or fleet-related products.
• Experience with cloud data infrastructure such as AWS, GCP, or similar.
• Experience with scheduled production pipelines, batch processing, or workflow orchestration tools.
• Experience handing over ML solutions to internal engineering or data teams.
• Previous experience in startup or product-company environments.

About Jakala 

We are Jakala — a data, AI and experience agency. Our team builds production-grade web applications and data-driven solutions for enterprise clients, much of which is in the healthcare and life sciences space. This particular team works closely with R&D, automating lab and scientific workflows: building web applications that capture, integrate and surface research data, and the services and integrations behind them. The work rewards engineers who care about correctness, reliability and clean delivery to clients who depend on the results. 

We are looking for a Senior Full Stack Developer to help build and deliver these applications, take ownership of meaningful parts of the system, and contribute to the technical decisions that shape them. As the scope of our work continues to grow, we want an experienced developer who can move comfortably across the stack and raise the quality of what we ship. 

What you'll do 

• Build across the stack. Design, develop and support web applications end to end — frontend interfaces and the backend services and APIs behind them. Build new features, improve existing functionality, and keep the codebase healthy as it grows. 
• Integrate data and services. Design and integrate REST APIs, third-party services and enterprise data sources. Much of the value in lab-automation work comes from reliably getting data in and out of systems, so robust, well-tested integrations matter. 
• Improve performance and reliability. Profile and tune applications, address bottlenecks, and make deliberate choices that keep systems fast, stable and maintainable over the long life of a client engagement. 
• Shape technical decisions. Participate in technical discussions, contribute to architectural choices, review code and support other developers. We want someone who improves the team, not just their own output. 
• Apply AI where it earns its place. Most of our work here is solid full-stack engineering, but AI shows up where it genuinely helps — LLMs for making sense of unstructured data, and the occasional GenAI project between lab-automation engagements. We have also trained a computer-vision model for one engagement. You don't need a machine-learning background, but curiosity about applying these tools well is a real plus. 

What we're looking for 

• 5+ years of experience in full-stack development — you can own a feature from database to UI. 
• Ability to work independently and take ownership of technical solutions. 
• Solid experience with Python on the backend. 
• Strong TypeScript and experience with React or Vue on the frontend. 
• Comfortable writing and maintaining automated tests (Vitest, Pytest, or equivalents). 
• Experience working with relational databases — MySQL and/or PostgreSQL. 
• A good understanding of REST APIs and how to design and integrate them well. 
• Fluency with Git and modern development workflows. 
• Experience with Docker and containerization. 
• Basic AWS or other Cloud infrastructure experience. 
• Upper-intermediate English or above, sufficient for day-to-day communication and technical discussion. 

Nice to have 

• Exposure to AI-related features — LLM integrations, RAG, or AI-powered workflows. 
• Any machine-learning or computer-vision experience. 
• Basic Terraform and CI/CD pipeline knowledge. 
• Familiarity with Flask-RESTful or similar REST frameworks. 
• Experience with data-integration patterns: external APIs, document ingestion, and enterprise data sources. 
• Fluent usage of AI-assisted development tools (Claude, Cursor, Copilot and the like) in your own workflow. 

What you'll get 

• Competitive compensation based on experience and skills. 
• 20 working days of paid vacation plus paid sick leave. 
• Health insurance package. 
• English language classes and learning support. 
• Coverage for courses, certifications, and tech conferences. 
• Fully remote working environment with flexible hours and reasonable overlap for collaboration. 
• Long-term, varied projects with real influence over technical decisions, in a collaborative team with minimal bureaucracy.
