We're looking for an architect to own the target-state architecture of our web platform and steer six engineering teams toward it.You'll have the final say on technical direction and work directly with team leads and engineers to put it into practice — aligning people through influence and clarity rather than authority.Most of your impact is upstream: translating business strategy into a coherent technical strategy, framing problems, and reducing risk while direction is still easy to change.You'll architect for sustained growth — horizontal scalability and the cross-cutting qualities (performance, reliability, maintainability, and the rest) that determine whether a platform keeps improving or stalls as users, data, and teams grow.We build a data-intensive B2B SaaS platform on Java 21, Spring, and AWS.
 

Requirements:

• 10+ years building production software, several of them in a dedicated architecture capacity, primarily on Java / Spring or C# .Net or Python.
• Demonstrated ownership of platform-level architecture spanning multiple teams.
• Deep distributed-systems expertise — microservices, event-driven and event-sourced designs.
• A proven record of scaling systems through real growth in traffic, data volume, and contributing teams.
• Command of data, caching, and search architecture (PostgreSQL, Redis, Elasticsearch) and of cloud-native operations — Kubernetes / EKS, Infrastructure-as-Code (Terraform), and CI/CD — with the ability to design infrastructure as a reusable, governed platform.
• Strong grounding in observability practices — instrumentation, distributed tracing, and defining SLOs/SLIs for production systems.
• Advanced security expertise — secure-by-design architecture, authentication and authorization, and data protection across the stack.
• Fluency moving from deep technical discussion with engineers to strategic trade-off framing with executives.
• The self-direction to be the senior-most architectural voice, aligning teams through influence and clarity.
   

Nice to have:

• High-traffic, data-intensive web experience at scale.
• AWS certification (Solutions Architect – Professional).
• Experience introducing AI-assisted, agentic development practices across the engineering lifecycle.
• Experience driving an organization through ISO 27001 and SOC 2 compliance programs.
   

Responsibilities:

• Define and own the north-star architecture, the guiding principles, and the guardrails that keep six teams coherent without becoming a bottleneck.
• Establish lightweight architectural governance — reference architectures, Architecture Decision Records, an RFC process, and a tech radar — so decisions are deliberate, documented, and durable.
• Drive domain decomposition and service boundaries (DDD, bounded contexts), and design event-driven systems with sound consistency, idempotency, and resilience semantics.
• Set the observability strategy — metrics, logging, tracing, SLOs, and alerting standards — so teams can understand system behavior, debug quickly, and operate confidently at scale.
• Shape initiatives upstream: frame the problem, weigh build-vs-buy against total cost of ownership, and set a defensible long-term direction before engineering commits.
• Treat security as a first-class architectural concern: secure-by-design, zero-trust principles, threat modeling, and data protection across the stack.
• Set the infrastructure architecture and Infrastructure-as-Code standards (e.g. Terraform).
• Build proofs of concept to validate direction and prove out emerging technology before it becomes a commitment.
• Mentor senior engineers and raise the architectural maturity of every team.

Project Foundation launched by The Fourth Law and Odd Systems is a semiconductor initiative to mass-produce thermal imaging sensors for Ukraine, the rest of Europe and the United States.

The initiative covers the development of LWIR sensors and the deployment of a network of partner-operated and in-house manufacturing facilities. It will create a new industrial base for defense and civilian needs and supply affordable sensors to manufacturers of drones, vehicles, and robotics.

The first sensors under the initiative are expected as early as 2027.

The Fourth Law is a leading Ukrainian manufacturer of autonomy technologies for drones. Our solutions are codified according to NATO standards and are currently utilized by over 50 units of the Security and Defense Forces of Ukraine, as well as 20+ drone manufacturers.

Odd Systems is a defense technology company specializing in the development and manufacturing of thermal imaging cameras. It was founded by a group of entrepreneurs, engineers, managers, and tech enthusiasts with prior experience at a number of international technology companies.

Purpose of the Role: The MEMS / Semiconductor Processing Specialist develops and owns the step-by-step cleanroom process flow that takes the microbolometer from deposited films to a released, suspended structure. This is a hands-on process engineering role covering photolithography, thin-film deposition, and sacrificial layer etching — both isotropic and anisotropic — with direct responsibility for releasing delicate suspended structures without damage or collapse. The role works in the Eindhoven R&D lab alongside the IC/MEMS Integration and Simulation Engineer and the wider technical cohort, and reports to the CTO.

 

Key Responsibilities:

•  Develop and document the end-to-end cleanroom process flow for microbolometer fabrication, from film deposition through structure release.

•  Own photolithography process steps: mask design coordination, exposure and develop parameters, and critical-dimension control.

•  Own thin-film deposition steps for sacrificial and structural layers, optimizing for uniformity, stress and compatibility with downstream process steps.

•  Develop and tune sacrificial-layer etch processes, both isotropic and anisotropic, to reliably release suspended microbolometer structures without stiction or membrane damage.

•  Troubleshoot yield and process excursions, working from wafer inspection and test data back to root cause.

•  Support equipment procurement, installation and commissioning in the new R&D lab, in coordination with the Technical Programme Manager.

Experience and skills we are looking for:

•  A degree in materials science, microelectronics, physics, or a related field, with hands-on cleanroom process experience.

•  Direct experience with photolithography, thin-film deposition (e.g. PECVD, sputtering) and wet/dry etching in a MEMS or semiconductor cleanroom.

•  Working knowledge of sacrificial-layer release processes and common MEMS failure modes, including stiction and stress-induced curling.

•  Comfortable developing new process flow from first principles, not just running an established recipe.

•  Fluent English, with the communication maturity to work with an international, partly Ukrainian team.

It’s a plus if you have: 

•  Prior work specifically on microbolometers, uncooled IR detectors, or other suspended-membrane MEMS devices.

•  Experience commissioning cleanroom process equipment as part of a new lab or fab standup.

•  Familiarity with ISO Class 7 or better cleanroom operating discipline.

•  Based in, or willing to relocate to, Eindhoven for the Odd Factory One R&D lab.

We are not just looking for employees, but for like-minded individuals who share our values and are ready to build the future of Ukrainian MilTech.

Full-Stack Developer at FlashProxy

Remote, full-time. Ideally someone in Eastern Europe who can work hours that overlap with GMT+3.

FlashProxy sells proxy and IP infrastructure on subscription. Small team, so you'd work directly with the founders and actually own your work instead of pushing it through endless approvals.

We need a full-stack dev to handle the software side: our website, our APIs, and the internal dashboards the team runs on. Long-term and full-time, not a short contract.

What you'll do

• Build and maintain our website
• Design and extend our APIs
• Build internal dashboards and tools for the team
• Own features start to finish, not just code someone hands you

What we need

• A few years of solid full-stack experience, strong on both front and back end
• Good with API design and databases
• Someone who can run with things on their own and cares about doing them right
• Fluent English, since you'll be talking to us daily

Stack (roughly): TypeScript, React/Next.js, Node, Postgres, Supabase. You don't need all of it if you pick things up fast.

Later on there's room to get into the infrastructure side, the networking that actually runs the product, and to start helping clients with the technical stuff. Something to grow into, not a requirement now.

To apply: send a short intro, your GitHub or examples of what you've built, and the rate you're after.
