About TEKTELIC 
TEKTELIC is a global leader in LoRaWAN® IoT solutions headquatered in Canada - designing and manufacturing gateways, sensors, having our own network server, and focusing on end-to-end IoT infrastructure from its base in Calgary, Canada. Founded in 2009, we focus on three high-growth verticals: Industrial (Oil&Gas), Smart Buildings, Asset Tracking & Personnel Monitoring, and Digital Medicine. Our carrier-grade products are deployed by hundreds of LPWAN operators worldwide. 

*Mandatory requirement: we consider only Kyiv-based candidates for this role.
 

About the Role 
We're hiring our first AI Automation Specialist to lead applied AI across the company. This is a hands-on, cross-functional role: you'll sit with teams in Sales, Operations, Finance, and beyond, find the work that drains their time, and replace it with reliable AI-powered workflows. 

This is an implementation and ownership role, not a research one. You won't be training models or doing data science — you'll be composing existing AI tools, APIs, and no-code/low-code platforms into workflows that run in production, and you'll own them once they're live. If you like turning "we waste ten hours a week on this" into something that just works, this is your role. 
 

We’re looking for someone long-term, at least a year commitment. 

Responsibilities 

• Assess each department's workflows to identify high-value opportunities for AI automation (repetitive, multi-step, or judgment-assisted tasks). 
   
• Design and prototype agentic workflows (multi-step AI agents, tool integrations, approval/human-in-the-loop checkpoints) tailored to each department's needs. 
   
• Act as the internal point of contact between departments for ai transformation 
   
• Select and configure the right tools/platforms (e.g., Claude Cowork, MCP connectors) for each use case 
   
• Monitor deployed workflows for performance, drift, and failure modes, and iterate or retire workflows that underperform. 
   
• Track adoption metrics per department and report progress to leadership. 

Requirements 

• Experience in process automation with AI, systems integration, business-process optimization, or a closely related field. 
• Ability to communicate across both technical and non-technical teams. 
• Strong process-mapping and business-analysis skills — the ability to translate a business problem into a working, monitored automation. 
• An ownership mindset: you care about reliability, edge cases, and proving impact — not just shipping a demo. 
• Hands-on experience with workflow automation platforms — any of n8n, Make, Zapier, or Power Automate. 
• Comfort with APIs, webhooks, and JSON, plus the ability to write light scripts (Python or JavaScript) when a no-code tool hits its ceiling. 
• English level: Upper-Intermediate. 
   

*This is an applied automation role. Machine learning, model training, algorithm development, and data science are not part of this position. 

What We Offer 

• Real ownership from day one — you'll define how AI works across the whole company, not just execute someone else's plan. 
• Direct impact and visibility — your work touches every department and is reported to leadership. 
• Modern tooling and autonomy to choose the right platforms for the job. 
• Competitive salary  
• Health insurance + Well-being program (250 USD/year) 
• Paid time off + extra Christmas week 
• PE accounting support 
• Supportive, collaborative team 
• Engaging Team events

• Initiative — proposes improvements instead of waiting for instructions

We offer

• Competitive salary
• Reservation from mobilization
• On-site work with access to hardware and lab facilities
• Office in Kyiv with shelter access, generator and Starlink
• Impact on improving our country's defense capabilities
• 21 days of vacation + public holidays, sick leaves

We have built a team of talented professionals from all over the globe, who are working to continually improve the experiences of our players. We are not looking to just be part of the industry, but to revolutionize it.

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.

What you will be doing
• Design, evolve, and maintain core libraries, framework extensions, and shared components used across all engineering teams
• Take ownership of system performance, scalability, and high-load architecture, ensuring core services can handle massive throughput with low latency
• Proactively monitor production behavior, investigate complex application/database performance bottlenecks, and introduce advanced metrics, dashboards, and alerting systems
• Establish and advocate for best practices in concurrency, memory management, and resource utilization across the backend ecosystem
• Collaborate with cross-functional teams including backend, web, mobile, QA, and product teams
• Take ownership of specific functional areas within our large-scale architecture
• Leverage AI tools and assistants as integral parts of your development workflow—from system design to code review
• Contribute to maintaining high test coverage, predictable production behavior, and seamless scalability
• Drive engineering excellence through modern practices and continuous improvement

What we are looking for
• Deep, low-level understanding of Java internals (JVM, GC behavior, memory management, concurrency/multithreading, and performance profiling)
• Advanced knowledge of relational databases (PostgreSQL), including query optimization, indexing strategies, locking mechanisms, and connection pooling under heavy load and distributed systems architecture, specifically high-throughput event streaming with Kafka (partitioning, replication, consumer group rebalancing, and tuning).
• Strong system design, troubleshooting and debugging capabilities
• Comfortable and proactive in using AI coding assistants (GitHub Copilot, Claude Code, etc.) as productivity multipliers
• Practical experience validating, refining, and taking ownership of AI-generated output
• Upper-intermediate or higher level of English

Nice to have:
• Proven track record of building or maintaining shared libraries, SDKs, or internal tooling in a large-scale engineering organization.
• Hands-on experience with APM tools and observability stacks (Prometheus, Grafana, ELK) with the ability to define meaningful SLOs/SLIs, custom metrics, and proactive alerts.

Main technologies: Java, Spring, Spring Boot, Ebean-ORM, Quartz, Maven, Resteasy, Flyway, PostgreSQL 15, HTTP/Websockets, Netty, K8S/Docker, GCP, Jenkins, ELK, Grafana.
