About the Role:

We are looking for a Senior Software Engineer to design, build, and own significant components of the core query engine of a large-scale distributed data platform. You will lead work across query planning, optimization, and execution — driving architectural decisions, mentoring middle engineers, and pushing the platform's performance and scalability boundaries across all major clouds.

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 significant components of the query engine — planner, optimizer, execution operators, memory management, and data access layers.
• Write and review high-quality, performance-critical code in Java and/or C++.
• Own end-to-end delivery of features from technical design through production rollout.

• Partner with US-based engineering leads on design reviews, architectural decisions, and roadmap execution.

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 deep understanding of OOP, systems design, memory management, and concurrency. Candidates strong in both are especially valued.
• SQL & Data: Advanced SQL skills and strong understanding of query execution internals — planning, optimization, and operator implementation.
• Data processing systems experience: Demonstrated experience building or extending data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 5+ years in backend/systems software engineering, with a track record of owning significant components.
• CI/CD & DevOps: Solid experience with Jenkins and modern engineering workflows.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes.
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and rigorous code review practices.
• 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.
• Leadership: Prior experience mentoring engineers, leading technical designs, or owning components end-to-end.

Desired Skills:

• Deep experience with Apache Arrow (columnar in-memory format).
• Hands-on experience with Apache Calcite (SQL parsing, planning, optimization framework).
• Experience with Gandiva or LLVM-based expression compilation and code generation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Deep familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Deep understanding of query planning, optimization (cost-based, rule-based), and execution internals.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Track record of performance optimization at the systems level — profiling, vectorization, cache/memory-conscious design.
• Prior experience contributing to open-source data infrastructure projects.

Job description:

What You'll Do

• Identify, approach, and onboard new affiliate partners with proven sales potential
• Manage and grow relationships with existing partners to maximize channel performance
• Drive traffic and sales growth across Amazon and our own website through the affiliate channel
• Build and maintain a reporting system to track performance, budgets, and key metrics

• Contribute to brand visibility and awareness as a secondary outcome of channel growth

What Success Looks Like

• Significant growth in channel sales volume within the first 12 months
• An expanded partner network, built through new affiliates with demonstrated sales potential
• High resource utilization and target attainment, starting from month 3
• A functioning reporting and testing system in place from month 2 onward

What We're Looking For

• A strong bias toward efficiency — the ability to drive significant results with minimal wasted effort
• Decisive, organized, and self-directed working style
• A fast learner, comfortable operating with a high degree of autonomy
• Willingness to put in the work needed to hit ambitious targets
• Strong negotiation and communication skills — you can build trust with partners quickly and professionally
• Prior experience in affiliate marketing, e-commerce, or Amazon growth roles (Health & Wellness category experience is a strong plus)
• Familiarity with FTC/FDA advertising guidelines for supplements is a plus, given the regulatory sensitivity of health claims in this category

What We Offer

• Direct impact on company growth and operations
• Close collaboration with founders from day one
• High autonomy and real ownership
• Remote-first, with flexibility and trust
• Competitive USD-based compensation with bonuses
• Room to grow as the business grows

We run an internal data platform behind a talent representation intelligence product that maps out the entertianment industry.
 

We are rebuilding the platform (legacy Symfony/Angular → Django + React) because the current system stores its most valuable data as unstructured text and can't support where the product is going. . This is not a greenfield toy and not a rescue job — it's a planned rebuild with an unusual amount of groundwork already done:

• A product & architecture document with the domain model decided: what each module means, what dies, what changes, and the conventions (append-only history, structured-at-entry, derived-values-never-facts, and more)
• An epic breakdown with dependency order and explicit definitions of done
• A decisions register — every product ruling logged, searchable, current
• Approved feature specs for the major new modules (representation history, deals/endorsements restructure, awards, drafts)
• A migration standard: raw-row archives, legacy-ID mapping, conflict review queues, rehearsed cutover — nothing silently dropped, nothing silently merged
   

Your job is to design and build within that system: propose schemas and migration plans per module (we call these build contracts — you propose, product approves, then you build), stand up the foundation (auth, field-level permissions, API-first architecture), build the cross-cutting primitives (audit log, unified sources, soft delete, lookups), and run a phased legacy migration where reconciliation counts get reviewed, not just produced.
 

How we work — read this part twice:

• The documents are the spec; the legacy code is not. Many current features are unused and several database tables are mislabeled (we've mapped this). When you hit a question about what something should do, you ask — you don't resolve it from old code. We answer questions daily, in writing, fast.
• Gates are real. Every epic starts with your proposed schema + migration plan; implementation starts after approval. Epics close when their definition-of-done closes — including a researcher completing the workflow without your help — not when the tasks are checked off.
• AI tooling is welcome and expected. We assume you'll use agents/copilots — we do. What we hire for is what the tools can't do: judgment. You verify what your tools produce against the real schema and the real data before it reaches us. "The agent said so" is not a source. (Our favorite recent bug: a generated diagram claiming a name column was an integer. The person who catches that is who we're hiring.)
• Evidence over memory. Unknowns get investigated — code usage, row counts, what breaks — and then ruled on. We don't guess.
  
  You're a fit if:
• Senior Django + React, with real ownership of at least one system end-to-end (schema through UI through deployment)
• You've done at least one legacy migration or system replacement and can talk concretely about what went wrong and what you'd do differently
• You read before you build — genuinely. Our last mismatch was a capable developer who never opened the app or the documents; the interview is designed to detect this, so if it's not you, save us both the call
• You're comfortable proposing designs to a non-engineer product owner who is deeply involved, defending them in writing, and being overruled on product grounds without sulking
• Strong written English; async-first habits; you leave a paper trail by default
• Bonus, not required: search infrastructure (Typesense/similar), data-pipeline/ETL work, having worked alongside scraper/ingestion systems, PostgreSQL depth

We’re building a new product team and looking for the first key engineer to join the project.

This is not a role where you’ll simply contribute to an existing codebase. You’ll have real ownership over architecture, technical decisions, engineering standards, and the foundation of the product from day one.

The project is in the MilTech space, involving UAVs and telemetry systems.

What you’ll do

• Build a C++ system from scratch, from architecture to production
• Design scalable and maintainable software
• Work with multithreading, concurrency, performance, and memory management
• Make key technical and architectural decisions
• Help establish engineering processes, standards, and best practices
• Eventually contribute to building and shaping the engineering team

Requirements

• Strong Modern C++ (C++17/20) experience
• Solid understanding of:
  • Systems programming
  • Memory management, RAII, smart pointers
  • Multithreading and concurrency
• Strong STL knowledge: containers, algorithms, iterators
• Understanding of algorithmic complexity (O(1), O(log n), etc.)
• Strong OOP knowledge and SOLID principles
• Experience with architectural/design patterns
• Git, CMake, GCC/Clang
• Experience with linters and static code analysis
• Ability to work independently and take ownership of technical outcomes

Nice to have

You don't need experience with all of these. A strong C++ foundation and willingness to learn are more important.

• Networking: TCP/UDP, sockets, asynchronous I/O
• MAVLink: telemetry and command communication with UAVs/robotics
• GStreamer: video-stream processing, H.264/H.265 encoding/decoding, low-latency pipelines

Who we're looking for

Strong Middle or Senior engineer.

We're looking for someone who can operate independently, make technical decisions, and eventually help shape the engineering team.

❌ Not a fit: candidates with only superficial knowledge of C++, multithreading, or networking. We need hands-on engineering experience, not just exposure to these technologies.

What we offer

• Competitive market compensation
• Fully remote
• Official employment with mobilization reservation for eligible candidates in Ukraine, or cooperation via FOP
• Paid AI tools for development
• High level of technical ownership
• Opportunity to build a product and engineering team from the ground up
