Jobs at Djinni

Build what happens behind the query.

Work on the core of a high-performance data platform — query planning, optimization, distributed execution and performance at scale.

About Our 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 Senior Software Engineer to work on the core query engine of a large-scale distributed data platform. You will own significant components across query planning, optimization, and execution — both driving improvements and acting as a trusted owner of production quality: diagnosing complex customer-reported issues and delivering safe, well-tested fixes across supported release lines. Engineers with staff-level scope and ambitions are very welcome.

This is a systems-level, backend engineering role focused on distributed data processing internals — not application development or CRUD services.

Responsibilities

• Architect, design, and implement query engine components — planner, optimizer, execution operators, memory management, and data access layers
• Diagnose and resolve complex production and customer-reported issues across the full query path — correctness, performance, memory, concurrency, resiliency, and compatibility
• Develop, review, and backport fixes across multiple supported release lines; strengthen regression prevention
• Write and review high-quality, performance-critical code in Java and/or C++
• Analyze query profiles, execution plans, logs, and telemetry to drive performance optimization — profiling, benchmarking, and eliminating bottlenecks in latency- and throughput-sensitive paths
• Integrate with columnar formats, open table formats, and connectivity drivers
• Improve regression tests, diagnostics, and observability; contribute to CI/CD architecture and quality processes in Jenkins
• Mentor middle engineers, lead code reviews, and help set technical standards

• Debug complex cross-layer issues spanning query planning, distributed execution, memory management, and I/O, partnering with US-based engineering leads

   

Required Qualifications

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field
• 5+ years in backend / systems software engineering with a track record of owning significant components end-to-end
• Strong proficiency in Java or C++ (comfort with both is especially valued), with deep understanding of OOP, systems design, memory management, concurrency, and asynchronous programming
• Advanced SQL and solid understanding of query execution internals — planning, optimization, operator implementation
• Experience building or extending data processing systems: query engines, distributed databases, ETL/ELT, or analytical platforms
• Ability to assess change risk in a mature production system; experience supporting software across multiple versions, branches, or customer environments
• Hands-on experience with Jenkins and modern CI/CD workflows; Docker and Kubernetes
• Hands-on experience with at least one major cloud (GCP, AWS, or Azure)
• Confident Git/GitHub workflows and rigorous code-review habits
• Comfortable with AI-assisted development workflows — using modern AI tools for code comprehension, debugging, and test generation, and critically validating their output
• Prior experience mentoring engineers, leading technical designs, or owning components end-to-end
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team

• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

   

Desired Skills

• Apache Arrow (columnar in-memory format) and SQL planner/optimizer frameworks such as Apache Calcite
• LLVM-based runtime expression compilation / code generation
• Open table formats — Apache Iceberg, Delta Lake, or Hudi — and columnar file formats such as Parquet, Avro, or ORC
• MPP query engines (Presto, Trino, or similar); background with distributed data platforms such as Spark, Snowflake, or Databricks
• Deep understanding of query optimization (cost-based, rule-based), vectorized execution, memory management, spilling, and caching
• Connectivity drivers: JDBC, ODBC, Arrow Flight
• Managed Kubernetes (GKE/EKS/AKS) and multi-cloud exposure; Terraform; cloud object storage (AWS S3, Azure Data Lake Storage, Google Cloud Storage)
• SaaS operations experience: incident response, profiling, observability, release and backport processes

• Systems-level performance work and open-source contributions to data infrastructure projects

   

Details

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team

This role isn't just a support queue. We see it as a growth seat - and we're not big on micromanaging how you run it. The person closest to our customers' problems is also best positioned to write the content that prevents them, promote what we're building, and spot expansion opportunities with the accounts they already talk to every day. If you're comfortable owning that end-to-end and turning recurring headaches into content, promo, and pipeline, you're our kind of person. How far you take it is largely up to you. 📈

Preferred Location: Remote • Full-Time • (Candidates based in Czech Republic, Ukraine, Poland, or the UK preferred, office in Prague).

   • Collect and relay product feedback to shape the roadmap
4. AI-Powered Workflows
   • Work with our integrated AI to triage and handle support workflows
   • Own the quality of our AI support: review AI conversations daily, find where it gets things wrong, vague, or off-tone, and fix the root cause
   • Continuously improve the AI through better prompts, knowledge base content, escalation rules, and guardrails
   • Define when the AI should answer, when it should ask a clarifying question, and when it should hand off to a human
   • Track and report on AI performance: resolution rate, handoff rate, accuracy, customer satisfaction, and recurring failure patterns
   • Stay current on AI models and tooling, and test new models, features, and approaches against real support conversations to decide what is worth adopting
   • Build agents for further automation (ticket tagging, bug reproduction, billing lookups, draft replies, and more)
   • Treat every bad AI answer as a bug to be understood and fixed, not just corrected once
5. Growth Opportunities
   • Write technical articles and case studies from conversations
   • Spot upsell/upgrade potential in the support queue
   • Spot new development and growth opportunities
   • Represent FansAPI in developer communities as a knowledgeable presence

✅ Highly organised, self-directed, and comfortable operating in a small, fast-moving team

Bonus Points For:

⭐️ Proficiency in additional languages beyond English - any language is a plus given our international customer base

⭐️ Understanding of AI support tools and how they’re used in customer-facing workflows (chatbots, AI-assisted ticket triage, automated responses, and knowing where human handoff matters)

⭐️ Familiarity with Claude Cowork or similar AI workflow automation agents

⭐️ Experience with Laravel 13, Inertia, and React

⭐️ Familiarity with the Creator ecosystem - creator agencies, CRM tools, or fan engagement platforms

⭐️ Experience writing or maintaining technical documentation

⭐️ Background in developer support, DevRel, or SaaS technical support
