Ameriland Transport is a U.S. trucking company built on the owner-operator model. We currently run a fleet of 60+ trucks, and our goal over the coming period is to grow to 100−150 trucks. We already have a recruiting team talking to candidates every day, and marketing campaigns generating leads. What we’re missing is a strong leader who can bring these pieces together into one system, hold everyone accountable for results, and help both teams work smarter.
What You’ll Do
You’ll take full ownership of our Driver Recruitment & Marketing Division and be accountable for the entire funnel — from ad spend to a new owner-operator joining the company:

• Oversee advertising campaigns (Meta, Google, Indeed, and other sources): what’s running, how much is being spent, and what quality of leads it’s producing.
• Evaluate outsourced advertising and email marketing specialists — and replace them if results fall short.
• Track ad creatives: which banners, videos, and offers are performing, and when new ones are needed.
• Checking the website, SEO, and email campaigns current, functional, and professional.
• Support the recruiting team: monitor lead response time, follow-up, conversion, and the handoff to the Safety department.
• Checking the website, SEO, and email campaigns current, functional, and professional.
• Make sure recruiters always have accurate, up-to-date information about the company’s program, pay, and requirements.
• Identify and test new lead sources and new platforms for driver acquisition.
• Build clear reporting and KPIs: cost per lead, cost per qualified lead, lead-to-driver conversion, and cost per activated driver.
• Review the full funnel weekly and bring concrete recommendations for improvement.
   

Who We’re Looking For
This isn’t a task-executor role — we need someone who thinks in systems and is comfortable owning the end result:

• Required: hands-on experience in theU.S. trucking / logistics industry — you need to genuinely understand how this business works.
• Required: experience recruiting or hiring drivers or owner-operators — this is a must, not a nice-to-have.
• Good understanding of paid advertising, social media, email marketing, basic SEO, and conversion funnels. Marketing experience is a strong advantage, but experience in recruiting within the logistics industry, particularlyhiring Owner-Operators, is more important for this role.
• Experience managing people, vendors, or outsourced specialists.
• Comfortable reading advertising and recruiting analytics and making decisions based on numbers, not gut feel.
• Strong organizational skills — able to run several projects at once without losing control.
• Good written and spoken English.
  Proactive, analytical, and comfortable pushing back on vendors or team members when results don’t add up.

What You’ll Get

• 
  Full ownership over how the division is built and run — you’ll design the system.
• Fully remote position, 3:00 PM — 12:00 AM Kyiv time.
• Base pay during the 3-month probation period: $2,500/month.
• Base pay after successful completion of probation: $3,000/month.
• A performance-based bonus system may be introduced in the future, depending on your performance, results, and initiative.
• Real growth alongside the company: our goal is to scale from 60+ to 100−150 trucks, and you’ll be one of the key people driving that growth.

• A team that’s already in place and ready for strong leadership: recruiters are on board, marketing is running — you won’t be starting from zero.
   

  Check yourself:

If you can answer «Yes» to all three questions below, you may be the candidate we are looking for:

1. Have you ever recruited truck drivers in the U.S. market?
2. Do you have experience sourcing truck drivers through platforms such as LinkedIn, Instagram, Facebook, and Indeed, as well as posting job vacancies on these platforms?
3. Do you have experience managing a team, monitoring their performance and KPIs (preferably a team of recruiters)?
   Ready to Apply?

If you know the U.S. trucking industry inside out, have real experience hiring drivers or owner-operators, and can bring order to numbers, people, and vendors — send us your resume. We’d love to talk.

DARC helps European, US and allied defence companies enter the Ukrainian market: strategy, partner matching, battlefield testing, communications.
 

The role

You are the technical authority on our side of the table.

You join pre-sale calls with the founders. A manufacturer explains what they build, and you work out during the conversation whether it meets a real Ukrainian requirement, what is missing, and what the honest answer is.
 

Once a client signs, you own the technical half of their go-to-market. You validate the product against how the war is actually fought, you produce feedback their engineers can act on, and you define what has to change and in what order.
 

You run the technical conversations between the client's engineers and their Ukrainian counterparty. Both sides describe the same problem in different languages, and someone has to carry the meaning across without losing it.
 

This is not an engineering role. You will not design or build anything. You assess, you translate, and you coordinate.

What we are looking for

• A working understanding of how this war is fought
• Expertise in unmanned systems across domains. FPV, fixed wing, fibre-optic, ground, naval. What they are built from, what fails first, and what is replacing what
• One area of real technical depth. Electronics and RF, EW, propulsion, optics and sensors, autonomy and software, materials, energetics. We need one properly, plus the literacy to follow a conversation in the others
• Experience sitting in front of an external customer and giving them a technical answer they did not want to hear
• Fluent English. You will speak and write to CTOs and heads of engineering every day
• Native Ukrainian
• Ability to explain a complex system in writing, without jargon, to a commercial reader
   

Strong plus:

• Background in a Ukrainian manufacturer's R&D or integration team
• Military engineering, acceptance testing, codification, or admission of product for supply
• Pre-sale, solutions or field application engineering at a component or systems vendor
  
   

What you will do

• Join pre-sale calls as the technical voice alongside the founders
• Assess a client's product against the Ukrainian requirement and write the honest answer, including when the answer is no
• Define what has to change for the product to work here, and in what sequence
• Structure and run technical negotiations between client engineers and Ukrainian partners
• Build the technical sections of proposals 
• Support integration and trials, and turn partner feedback into something a client's engineering team can act on
• Keep our own technical picture current. What is being used, what is failing, what is being replaced
   

What we offer

• Direct work with foreign manufacturers and tier-one players in Ukraine and abroad
• Visibility across dozens of foreign products and Ukrainian requirements at the same time, which is a view almost nobody has
• Travel to European defence exhibitions
• Competitive salary with a performance component tied to delivery on signed mandates
• Salary review every quarter

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

We are building a digital orthodontics platform with interactive browser-based 3D tools and backend mesh-processing services.

This is a hybrid role combining native computational geometry in C++, browser-based 3D development with Three.js and TypeScript, full-stack development with Angular and Node.js, and deployment of geometry-processing workloads to AWS.

You will be able to take a 3D feature through its complete lifecycle: implement the geometry algorithm, expose it through a backend service, build the browser interaction, and deploy the complete workflow to production.

Important: this is not a 3D visualization-only position. The role requires hands-on experience with mesh manipulation, computational geometry, 3D mathematics, and geometry-quality validation.

You Are

• A Software Engineer with commercial experience building 3D, CAD, mesh-processing, medical 3D, 3D-printing, scientific visualization, or similar systems.
• Strong in modern C++17 or later, including memory management, performance profiling, native libraries, and dependency management.
• Strong in JavaScript/TypeScript and experienced with browser-based 3D development using Three.js or raw WebGL.
• Experienced with computational geometry and direct manipulation of triangle meshes.
• Familiar with mesh topology, normals, boundaries, connected components, non-manifold geometry, coordinate systems, units, and numerical tolerances.
• Have implemented or integrated mesh operations such as repair, remeshing, simplification, smoothing, cutting, Boolean operations, offsets, distance queries, collision/contact detection, or registration.
• Have practical experience with at least one geometry-processing library or SDK such as VTK, CGAL, Open3D, libigl, MeshLib, OpenMesh, or similar.
• Comfortable with the mathematics behind 3D systems, including vectors, matrices, transformations, projections, quaternions, linear algebra, and spatial queries.
• Familiar with spatial data structures and acceleration techniques such as BVH, octrees, or k-d trees.
• Experienced with Three.js concepts including BufferGeometry, materials, cameras, raycasting, object transforms, interaction tools, and rendering-performance optimization.
• Have practical experience with Angular and reactive application architecture using RxJS or equivalent patterns.
• Have backend experience with Node.js and Express or a comparable framework.
• Comfortable integrating native C++ processing with web services through a CLI, native library, binding, API, or containerized worker.
• 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.
• Experience with Python, NumPy, trimesh, or similar geometry tooling.
• Experience with WebAssembly or compiling native C++ libraries for the browser using Emscripten.
• Experience with Web Workers, transferable buffers, SharedArrayBuffer, or moving CPU-intensive calculations outside the browser’s main thread.
• Experience with three-mesh-bvh, GLSL shaders, large-mesh rendering, or custom Three.js interaction tools.
• Experience evaluating third-party geometry SDKs, including benchmarks, licence restrictions, and headless deployment.
• Background in medtech, healthcare, dental CAD/CAM, scientific visualization, or 3D printing.

• Familiarity with AI-assisted development tools such as Cursor, Claude Code, or Codex.

   

What We Expect from You

• Own 3D features from geometry implementation through backend integration, browser tooling, and production deployment.
• Work directly with mesh data and geometry algorithms, not only with rendering and visual appearance.
• Define clear tolerances, invariants, validation rules, and quality checks for geometry operations.
• Identify cases where an operation cannot produce a reliable result and report them clearly.
• 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.
• Define stable contracts for mesh formats, metadata, units, coordinate systems, transforms, inputs, outputs, and errors.
• Package C++ geometry operations as reliable headless Linux workers using Docker.
• Deploy geometry workers to appropriate AWS compute services and orchestrate them using Step Functions, queues, and object storage.
• Implement asynchronous job execution, progress reporting, retries, timeouts, failure handling, and structured error reporting.
• Optimize geometry-processing time, memory usage, output quality, browser rendering, and data transfer.
• Write unit, integration, end-to-end, and geometry-regression tests.
• Create representative mesh fixtures and tolerance-based quality checks.
• Investigate issues across C++, Node.js, Angular, Three.js, Docker, and AWS.
• Participate in technical design discussions, pull-request reviews, and engineering best practices.

• Use AI-assisted development tools responsibly to improve development speed and code quality.

   

What We Offer

• Work on an innovative product in the medical-tech and 3D geometry domain.
• High ownership and direct impact on product and technical decisions.
• The opportunity to work across computational geometry, browser 3D, backend systems, and cloud infrastructure.
• Flexible working hours within the European time zone.
• Fully remote, full-time, long-term cooperation.
• A fast-moving environment where strong engineers can influence the product and architecture.
• Company-paid AI development tools.
• Professional development support, including courses and certifications.
• 20 paid business days of vacation.
• 5 paid sick-leave days.
• Paid national holidays.
