Role Overview

We are looking for a Senior Data Engineer to work on the data architecture behind our intelligence platform, across both our production data infrastructure and our work with multimodal data.

We operate on text, social media, geospatial, and time-series data at scale. A large part of the engineering challenge is in how that data is represented and connected: the same real-world entity can be modelled on a map, as a node in a graph, and as a pattern over time, and the value comes from being able to query and reason across those views together.

You'll bring hands-on experience with geospatial data, knowledge graphs, or entity-relationship systems across multiple data types. We care more about how you reason through architectural and technology choices than about any specific tool.

This is a hands-on, senior role with real ownership over architecture, execution, and technical direction.
 

Key Responsibilities

Multimodal Data & Entity Modelling

• Extract entities and relationships from text, social media, geospatial, and time-series data, and model them across map, graph, and temporal representations.
• Evolve our knowledge graph layer and make connected data usable for analytics, visualisation, and AI agents.
• Evaluate and prototype technologies for geospatial and graph workloads at scale

Core Data Platform

• Migrate production workloads from PostgreSQL to StarRocks.
• Improve ingestion and processing performance, and redesign product storage architecture for billion-row scale.
• Own the infrastructure your pipelines run on, including deployment, performance, and cost.

Requirements

• Hands-on experience building data systems for geospatial data, graph data, or knowledge graphs, ideally combining several data types.
• Experience with GIS tooling (e.g. PostGIS), graph databases (e.g. Neo4j, TigerGraph), or modelling graph data on relational or columnar storage.
• Strong architectural thinking and the ability to justify technology choices, run experiments, and change course based on results.
• Proven experience moving and processing data at large scale, with resumable, idempotent, and memory-safe pipelines.
• Experience working with data infrastructure beneath the managed layer, not only inside a ready-made SaaS platform.
• Ability to read query plans and change physical data layout to fix performance issues.
• Experience building and shipping production backend services in Python.
• Comfort owning infrastructure, including Kubernetes, Helm, Terraform, or similar tools.
• Fluent English.

Nice to Have

• Production experience with a columnar or MPP engine such as StarRocks, Doris, ClickHouse, BigQuery, or Snowflake, including partitioning, distribution, and indexing.
• Experience with Elasticsearch or OpenSearch at scale, including mappings, ILM, tiering, and reindexing.
• Experience with a long-running migration involving dual-write, reconciliation, and cutover.
• Knowledge of PostgreSQL internals.
• Experience with event-driven ingestion using Kafka or RabbitMQ.
• Experience with observability tools (Prometheus, Grafana, Loki), lakehouse formats (Parquet, Iceberg), and orchestrators such as Airflow.
• Background in threat intelligence, OSINT, geospatial intelligence, or defence.

We Offer

• Opportunity to contribute to a mission-driven startup and support prestigious clients, including governments worldwide, enterprise clients, and leading NGOs in tackling global security challenges.
• Autonomy and freedom to drive experiments and bring your own ideas to life.
• Flexibility of remote work, with the option to join our teams in Kyiv and Lviv.
• Flexible, unlimited time-off policy.

Work directly with a CTO who has 20+ years of building systems, on a product that is getting ready for launch. The LLM is at the core of it, the backend team is small, and your code goes into the first release.

We are hiring a Python backend engineer into our client's product team. Reviews here are detailed: you defend your decisions line by line and get feedback from someone who has seen most of the ways a system can fail. That is how you grow fast. The CTO also expects to hear "this is a bad idea" when it is one, with an argument behind it.

Use AI as much as you like. You own every line, whoever wrote it. You get a task and bring it back done: questions at the start, blockers raised the same day.

What you will do

• Own backend tasks from spec to production: API, data model, background jobs, integrations
• Build the layer around the LLM: checking model output, handling failures, quality tests
• Improve service stability before launch

What we need

• 4+ years of commercial development, Python as your main language. The framework is secondary
• You know how systems are put together: data structures and complexity, concurrency, queues, caches, transactions, indexes
• English Upper-Intermediate or higher: daily calls and written communication with the CTO
• Ukrainian or Russian for communication inside our team
• Nice to have: LLMs in production, asyncio, type hints and tests as a habit

Hiring process

1. We read your CV. If we have questions, we ask them in writing
2. Take-home task, AI allowed
3. Interview with our tech lead about your solution
4. Introduction to the client: interview with the CTO in English
5. After that the client will most likely give a take-home of their own, similar to ours. We go through it with our tech lead before you submit, and you defend it with the CTO at the final meeting

Terms

• You are employed by Tailored Tech and work inside the client's team. Full-time, fully remote, UA/EU time zone
• Paid probation, review of terms after it, then every six months
• Paid vacation and sick leave, AI subscriptions covered

To apply, send your CV and a few lines about the system you designed that you are most proud of.

English - B2-C1
Rate - Flexible

• Experienced with CMake, Linux, Docker, Git workflows, pull requests, and code review.
• Able to write automated tests for geometry code using fixtures, invariants, tolerance checks, and regression datasets.

• Able to investigate problems across the entire system—from incorrect geometry output to API integration, browser interaction, or cloud execution.

   

Will Be a Plus

• Experience with multiple geometry-processing libraries or commercial 3D SDKs.
• Experience with AWS services such as S3, SQS, Step Functions, ECS/Fargate, AWS Batch, Lambda, ECR, CloudWatch, and IAM.
• Experience designing asynchronous and long-running processing workflows.
• Experience with Infrastructure as Code using Terraform, AWS CDK, or CloudFormation.
• Experience with C++ bindings such as pybind11 or nanobind.

• Make practical engineering decisions that help us deliver quickly without unnecessary overengineering.
• Proactively identify geometry-quality, rendering, performance, memory, and scalability issues.
• Maintain clear contracts between C++ processing, backend services, and browser-based 3D tools.
• Be comfortable working in an evolving product with changing priorities and early-stage ambiguity.
• Review, test, and validate AI-generated code before using it in production.

• Communicate effectively with domain experts, frontend engineers, backend engineers, and infrastructure engineers.

   

Responsibilities

• Build and improve native C++ mesh-processing tools and libraries.
• Implement and integrate computational geometry algorithms for processing and modifying complex 3D meshes.
• Build interactive browser-based 3D tools using Three.js and TypeScript.
• Implement Angular components, services, state management, and user workflows for 3D features.
• Develop Node.js/Express APIs that connect browser tools with native geometry-processing services.
