About the Client

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role

We are looking for a Middle-level Software Engineer to work on the core query engine of a large-scale distributed data platform. You will develop features across query planning, optimization, and execution, contribute to performance-critical components, and help evolve the platform's ability to process massive analytical workloads across heterogeneous data sources.

• Develop and maintain features across the query engine — planning, optimization, execution, and data access layers.
• Write high-quality, performance-conscious code in Java and/or C++.
• Work with SQL semantics, query plans, and execution operators over large-scale distributed data.
• Integrate with columnar formats, open table formats, and connectivity drivers used across the platform.
• Contribute to CI/CD pipelines and automated testing — participate in build, test, and release workflows in Jenkins.
• Deploy and validate work in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker.
• Debug complex issues spanning query planning, distributed execution, memory management, and I/O.
• Collaborate closely with US-based engineering teams on design reviews, code reviews, and technical decisions.

Required Qualifications

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Java or C++, with solid OOP and software design fundamentals. Candidates comfortable with both are especially valued.
• SQL & Data: Strong SQL skills and solid understanding of relational and analytical data systems, including query execution concepts.
• Data processing systems experience: Hands-on experience with data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 3+ years in backend/systems software engineering.
• CI/CD & DevOps basics: Practical experience with Jenkins pipelines and modern development workflows.
• Containers: Working knowledge of Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency).
• Cloud: Comfortable operating in at least one major cloud (GCP, AWS, or Azure).
• Version Control: Confident with Git / GitHub workflows.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.

Desired Skills

• Experience with Apache Arrow (columnar in-memory format).
• Familiarity with Apache Calcite (SQL parsing, planning, optimization framework).
• Exposure to Gandiva or LLVM-based expression compilation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Understanding of query planning, optimization, and execution internals.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.

• Testing experience: 3+ years in backend/system test automation or SDET roles.
• CI/CD & DevOps basics: Practical experience with Jenkins pipelines and deploying/maintaining test environments.
• Containers: Working knowledge of Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency).
• Cloud: Comfortable operating in at least one major cloud (GCP, AWS, or Azure).
• Version Control: Confident with Git / GitHub workflows.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.

Desired Skills

• Experience testing REST APIs and backend microservices at scale.

We build AI-heavy software for commercial real estate lenders, covering loan origination, servicing, document extraction, and financial analysis.

We’re looking for an AI Product Delivery Manager to own the path from requirements → development → QA → release.

This is not a traditional PM or project coordinator role. We use AI agents to do the mechanical work — drafting tickets, documentation, test cases, and other delivery tasks. Your job is to define the work precisely, build effective agent workflows, and apply judgment to what comes back.

Schedule — read before applying

This role connects a European development team with a US business team:

• 10:00–12:00 Kyiv time — development team, Mon–Fri
• 19:00–21:00 Kyiv time — US team, Mon–Fri

Both are fixed. The hours between are flexible. Apply only if this schedule works for you long term.

What you’ll own

• Product delivery: sprint planning, backlog, scope, priorities and capacity
• Requirements: feature specs, acceptance criteria, and keeping wiki/designs/tickets aligned
• AI workflows: build agents that generate tickets, documentation, test plans, etc.
• QA: test new features, run regression, validate AI document extraction, and file defects with evidence
• Design review: compare implementation against Figma and catch gaps before release
• Product: participate in scoping and design decisions and represent the user

What we’re looking for

• 3+ years in product management, delivery management, product operations, QA, or a combination
• AI is already part of your daily workflow
• Hands-on experience with AI agents / Claude Code / MCP / Claude Skills / Cowork or comparable tools
• You can write specifications precise enough for an agent to produce useful output
• Strong judgment about when AI output needs verification — and you actually verify it
• Comfortable with Jira, Confluence/wiki, Figma, PDFs, spreadsheets and structured data
• Strong spoken and written English and Russian
• Comfortable running calls with both technical and business teams

Not a fit if your background is primarily marketing, growth, sales, or content.

Nice to have

• Commercial real estate, lending, fintech or insurance
• QA experience
• SQL or basic Python
• Document-heavy B2B software

How we work

AI tools are paid for and expected to be used daily. Small teams, short release cycles, direct access to customers, and a lot of autonomy.

You’ll be the connection point between the European development team and the US business team.
