About the Role

You'll own the full radar processing stack — from raw acquisition through detection and tracking. You report to the radar system architect: you own the software implementation of the waveform and detection strategy, and you feed back what's viable on compute, memory, and timeline. You’ll bridge the gap between theoretical DSP and high-performance, real-world deployment at Valkyrie Dynamics.

What You’ll Do

• Own the radar waveform and detection strategy
  • Chirp/FMCW design
  • Range-Doppler processing detection budgets (SNR, integration, CFAR)
  • Angle estimation to detect small, low-RCS UAV targets at high closing velocity
• Define and maintain the system-level requirements and budgets
  • Detection range, range/Doppler/angular resolution, update rate, power, thermal, and size
  • Write verifiable requirements so that meeting them validates the sensor
• Evaluate approaches across the integration spectrum, cascaded transceiver ICs, an integrated system-on-module, or a discrete RF front-end
  • Collaborate with the antenna engineer on a viable solution for channel count, LO/clock distribution, and phase-coherence strategy across the array
• Own and control the interfaces between subsystems
  • Ensure end-to-end signal chain from antenna to detection output holds together as one coherent system including:
    • Timing and synchronization (frame/trigger)
    • Transceiver-to-compute data path (sample rates, formats, latency/throughput)
    • RF/antenna boundary
• Own and continuously evolve the system model — effectively a digital twin of the sensor. During the evolution:
  • Maintain ICDs
  • Meet and manage performance metrics
  • Grow model fidelity over time, introducing the non-idealities and non-linearities that matter as complexity increases (phase noise, PA compression, quantization, channel mismatch, mutual coupling), and trace observed behavior back to the origin.
• Collaborate with the DSP engineer on the waveform and detection design
  • You lead the strategy, they own the implementation and pressure-test it for compute load, memory, and timeline — until the architecture is both performant and buildable
• Converge the open architecture questions to decisions on a schedule
  • Committing with the evidence available, revisiting only when new data (a budget, a measurement) actually changes the answer
• Able to work independently on a contract basis
• Must pass company security procedures
• Must communicate effectively in English

Preferred / Bonus

• Counter-UAV or defense radar experience specifically — small, low-RCS, maneuvering targets in cluttered environments
• Hands-on experience with integrated radar transceiver SoCs including integration tradeoffs they bring
• MATLAB Simulink
• Ukrainian or Russian speaking (Other languages are also great)

Engagement Details

• Type: Contract-to-permanent position
  • Starts as a contract engagement with an explicit track to a permanent lead role for the right candidate
• Rate: [TBD]
• Duration: [TBD]
• Location: Kyiv preferred, Hybrid
   
  • Hybrid: Must be able to temporary travel to Kyiv for on-site testing is heavily preferred (all expenses paid) — system bring-up and field validation against real targets, correlating measured performance against the model.

ABOUT THE ROLE

We are a climate technology team operating a multi-tenant SaaS platform used by carbon registries and project developers. Correctness matters here in a way it does not in most products: the records our customers create are written to a public ledger and cannot be edited afterward.

You would own quality end to end. That means the automated test estate, hands-on manual and exploratory testing, and being the first technical responder when a customer reports something that does not look right.

It also means something we think is underrated: because you will know each feature better than anyone once you have tested it, you will be the one who documents it, demonstrates it, and walks customers through it. We do not think that work belongs to someone who has never exercised the feature.

RESPONSIBILITIES

• Own the automated test estate: unit, API and end-to-end suites, and the CI pipelines that run them.
• Manual and exploratory testing, including release verification. Not everything worth catching can be automated, and we are not interested in a team that pretends otherwise.
• Regression strategy for a platform with a large surface area and frequent releases.
• Bug triage: reproduce, isolate, write the report a developer can act on without a second conversation.
• Feature documentation. Partner with the developer who built it, understand it properly, and write the documentation for it. You will have tested it, so you already know where users will get stuck.
• Demos of completed features, internally and to customers and partners.
• Front-line technical response and customer onboarding: reproduce what the customer reports, walk new customers through the platform, and answer the technical questions that come in.
• Test data strategy for a domain where realistic data is scarce and production data is sensitive.
• Performance and load testing, if that interests you. The foundation exists.

REQUIREMENTS

• Strong in both automation and manual testing. This is the core requirement. Candidates who are excellent at one and absent in the other are not a fit for this role.
• 4+ years in QA, with ownership of a test suite rather than only executing someone else's.
• API testing depth: REST contracts, auth, error paths, and what to assert beyond a 200.
• End-to-end and UI automation with a modern framework. We use Playwright; Cypress or Selenium experience transfers.
• Unit and integration testing in a JavaScript or TypeScript codebase.
• CI/CD literacy: able to read a pipeline, work out why a job fails, and fix it. You will own the workflows that run your tests.
• Formal test design: boundary values, equivalence partitioning, decision tables. We want deliberate coverage, not intuition.
• Able to judge whether a test actually proves anything. A green suite that asserts nothing is worse than no suite, and we will ask you about this directly.
• Able to write clearly for a non-engineer. Feature documentation is part of this role, not an afterthought handed to someone else.
• Comfortable presenting. You will demo features to customers and partners, and onboard new users onto the platform.
• Comfortable talking to customers. You will sometimes be the first person a frustrated user reaches.
• Willing to sit with a developer and ask questions until you genuinely understand a feature, rather than testing it from the ticket description.
• English at B2 or above for written technical discussion and calls.

NICE TO HAVE

• Load and performance testing with k6, JMeter or similar
  Test data generation, including synthetic or AI-assisted approaches
  Kubernetes literacy, enough to read logs and understand where a service runs
  MongoDB
  Exposure to blockchain, carbon markets or regulated reporting. Optional, we will teach the domain.

WHAT YOU WOULD WORK ON FIRST

• Being specific, because it is more useful than a list of adjectives:
• Taking ownership of an existing test estate and deciding what to keep, repair or retire.
• Bringing a substantial body of generated test coverage under review and judging what genuinely earns its place.
• Establishing regression coverage for a part of the platform that is currently verified by hand.
• Building a test data approach for a domain where realistic data is genuinely hard to obtain.
• Documenting and demonstrating the features shipping in the next releases.
• If you have spent years asking for the authority to fix a test pipeline properly, this role is that authority.

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 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.
• Drive performance optimization work — profiling, benchmarking, and eliminating bottlenecks in latency- and throughput-sensitive paths.
• Integrate deeply with columnar formats, open table formats, and connectivity drivers.
• Mentor middle engineers, lead code reviews, and set technical standards for the team.
• Contribute to CI/CD architecture and quality processes across Jenkins, containerization, and multi-cloud deployment (GCP, AWS, Azure via Kubernetes / Docker).
• Debug complex, cross-layer issues spanning query planning, distributed execution, memory management, and I/O.
• 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.
