Jobs

The Role

You’ll build and maintain the backend services behind our automations. What sets this role apart is how you work: we expect you to ship fast and efficiently by driving AI coding tools rather than hand-writing everything. You frame the problem, point the model at the right inputs and context, own the plan, and run a rigorous final code review. The AI writes most of the code — you’re the engineer who makes sure it’s correct, fast, and production-ready.

We’re looking for someone genuinely strong with modern AI tooling — treating it as a core part of the workflow, not a side experiment — including a solid AI harness with strong automated code validation and verification built in.

Responsibilities

• Design, build, and maintain backend microservices for process automation
• Deliver features fast using AI coding agents: scope the task, prepare inputs/context, define the plan, and review the output critically
• Investigate and reverse-engineer the behaviour of private/third-party APIs
• Integrate automations across the platforms and keep them reliable in production
• Optimize systems for performance, scalability, and reliability

• Collaborate with the team on architecture and technical decisions.

   

Required Expertise

• Solid engineering judgment: able to read, review, and correct AI-generated code and catch subtle bugs
• Strong Node.js / TypeScript backend background for scalable, high-load systems
• Microservices design with high availability and fault tolerance
• Experience with time-series/PostgreSQL workloads (TimescaleDB)
• Event bus and message queue familiarity (Kafka, RabbitMQ, SQS)
• Cloud platform knowledge (AWS, GCP) and containerization (Docker, Kubernetes)
• Problem-solving mindset for high-traffic systems
• Strong, hands-on AI-assisted development skills — daily use of coding agents (Claude Code, Codex, etc.) to write and ship code efficiently

• A robust AI harness with strong code validation/verification, so AI-generated changes are automatically checked before they land.

   

Requirements

• 5+ years of backend engineering experience (Senior level)
• Node.js, TypeScript, JavaScript proficiency
• Proven experience shipping code with AI coding tools
• Ukrainian language: native speaker level
• Full-time, fully remote position

• Global candidates considered

   

Benefits

• 20 vacation days + 10 sick days
• Flexible schedule, fully remote
• Sports, psychology, and health insurance budgets
• Education and English course funding
• Team-building events
• Personal Development Plans

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

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

We're looking for a Senior Python Engineer to become the technical owner of the backend platform: you decide how it is built.

The MVP is live and it proved the product works. Now it has to become a platform that holds under load, over unreliable networks, on a 24/7 production system - which means new services designed properly, an engineering standard that does not exist yet (Spec-Driven Development, AI-powered pipelines, CI/CD, review), and the old shortcuts retired along the way.

What you'll do

• Take full ownership of the backend: Django, DRF, FastAPI services, Celery, PostgreSQL, TimescaleDB, Redis, and the OPC UA components
• Audit the existing MVP end to end and define the refactoring strategy.
• Design reliable failover for site connectivity so telemetry and commands keep working over unstable networks
• Balance fast product validation against long-term platform stability, and re-prioritize when the business shifts
• Build AI-powered engineering workflows (agentic pipelines) and make Spec-Driven Development the standard
• Work with cybersecurity specialists on IEC 62443 and translate its requirements into platform architecture
• Set the engineering standards: code quality, reviews, CI/CD, testing, API stability

Must have

• 6+ years of commercial Python, with strong production experience across: Django and DRF, FastAPI (Pydantic v2), Celery, PostgreSQL, Redis, Docker / Docker Compose, pytest and CI/CD
• System design, hands-on: you have defined service boundaries, API contracts, data flows and scalable architectures for production - and can walk through decisions you made and what they cost
• Authorization models by design: RBAC, least privilege, Django/DRF permission systems, object-level permissions, and consistent enforcement across distributed services
• Resilient third-party integrations: retries with exponential backoff, rate-limit handling, Redis caching and invalidation strategies, graceful degradation when an upstream service goes down
• OPC UA - working knowledge: client/server model, namespaces, subscriptions, security modes
• AI-driven engineering: contract-first / Spec-Driven Development (OpenAPI/Swagger, Pydantic, gRPC), plus experience building or using agentic pipelines - CrewAI, LangGraph, or your own orchestration - to automate code generation, tests, documentation, review or integration validation
• English B2+

Nice to have

• Modbus TCP/RTU or other industrial protocols
• IEC 62443 / OT security
• TimescaleDB, InfluxDB or ClickHouse; MongoDB
• Redis beyond simple caching
• Observability: Sentry, Flower, structured logging
• Refactoring legacy production systems without downtime

Location: Remote European time zone (CET/EET)
Reports to: CMO

Level: Senior / Lead
