About Us

We are a US-founded early stage start-up with an R&D team located in Europe. Our mission is to make learning accessible, relevant, and individualized to keep up with the changing world. We are developing a personalized virtual trainer experience, integrating generative AI and learning engineering to build a VR simulator for immersive hands-on skills training. Our learning engineering approach customizes content and feedback in real-time, directly improving learning outcomes.

We're looking for a Senior Unity engineer to help build the client-side infrastructure of our training platform. This is not just one-off application work. You will build the client foundation that powers VR training simulations today, and additional client targets over time, connecting it to our server according to a defined client-server architecture. The role demands strong application architecture, on-device services, and performance optimization skills.

The Role

This is a hands-on individual contributor role focused on building and evolving key components of our platform's client-side architecture. You will build client infrastructure against a defined server-client architecture in which the server owns authoritative simulation state and logic, connecting the client to the server per spec and reflecting server-owned behavior faithfully on the device.

Key Responsibilities

• Own and drive key components of the Unity VR client architecture so they generalize across training simulations and, over time, additional client targets, rather than serving a single application.
• Build client-side infrastructure that connects to the server according to defined contracts and reflects server-owned state and behavior on the device.
• Co-design the client-server API with the backend, defining the data contracts.
• Develop tooling that supports content creators and other developers working on the platform.
• Use AI coding assistants as part of day-to-day development, and build and maintain the pipelines and validation that make their output reliable.
• Make pragmatic architectural decisions and manage technical priorities effectively in a fast-paced, ambiguous startup environment.

Requirements

• Demonstrated professional Unity and C# experience, ideally 5+ years, with a track record of shipping complex applications or products.
• A portfolio demonstrating experience architecting and refactoring large-scale Unity projects.
• Direct experience building for VR, in particular Meta Quest.
• A track record of building generic, reusable infrastructure and frameworks, not just one-off features.
• Comfort working within a defined client-server architecture and with established API contracts.
• A proactive and adaptable mindset suited for the dynamic and evolving environment of an early-stage startup.
• Excellent communication and collaboration skills in English, with experience working effectively in a remote, culturally diverse team.
• A genuine interest in using technology to enhance learning and education.

Nice To Have

• Experience targeting additional client platforms such as WebGL.
• Experience with data-driven or reactive component systems.

What We Offer

• A high-ownership role with direct influence on product direction, architecture, and user experience, and on company culture.
• A senior opportunity to build a platform from the ground up and contribute to its growth and commercialization.
• The flexibility of a fully remote position, with working hours flexible across European time zones rather than tied to US hours.

DMT Business Development is a leading B2B lead generation and appointment setting agency. We create tailored & effective strategies for clients based on their needs and goals. Our team generated over 2m leads for hundreds of clients and booked 10k+ appointments with businesses of any scope.

Currently we have an open vacancy for Client Growth & Retention Lead.

Working conditions:
 

• Working hours: Monday-Friday, 2 PM to 10 PM (Kyiv time);
• 20 paid vacation days per year and company events.
• A young and friendly team environment.
• Benefits include company guarantees, bonuses, and corporate event.
  
  Responsibilities:
   
• Lead and develop a team of 3–5 outbound specialists (SDRs, appointment setters, campaign managers);
• Own client retention: proactively manage at-risk accounts, drive renewals and upsells;
• Build and maintain repeatable playbooks — onboarding, escalation, QA, campaign optimization;
• Be the main point of contact for US/Canada clients: status calls, strategy reviews, tough conversations;
• Monitor and improve campaign performance: email deliverability, LinkedIn outreach, reply rates, appointment metrics;
• Work closely with internal ops to ensure smooth delivery and fast issue resolution.
  
  Requirements:
   
• 3+ years in B2B lead gen, appointment setting, or outbound agency environment;
• 2+ years managing a team (3–5 people);
• Proven track record of retaining and growing a client portfolio — you know how to save a client before they churn;
• You've built things that outlast you: onboarding docs, escalation flows, campaign frameworks;
• Deep understanding of outbound mechanics: email infrastructure, LinkedIn, sequencing, KPIs;
• C1+ English — comfortable running strategic calls with founders and executives in North America;
• Available during US/Canada business hours (overlap with EST/PST required)

We are looking for an experienced Technical Lead & Product Manager for a .NET development team. You should be strong in problem-solving, system design, and solution architecture, with a proactive approach to your work. You will lead the team technically, own the product roadmap, work directly with customers and stakeholders, take initiative and drive work to completion from planning through deployment.

Must-have:

Technical

• C# 7+, .NET Core, MVC 5, Web API
• MS SQL, Azure Table/Queue, Blob Storage
• Distributed caching & caching strategies
• Dependency Injection (Autofac)
• REST API design, secure authentication (Cookie, OAuth, JWT, OpenID)
• SOLID principles, Clean Architecture, maintainable & scalable code
• 10+ years in software development

Leadership & Product

• Led a dev team — planning work, reviewing code, keeping delivery on track
• Worked with stakeholders or customers to figure out what to build and why
• Comfortable running standups, planning sessions, and retrospectives
• Can write a clear spec or technical doc without it turning into a 40-page essay
• Happy to jump on a call with a customer, show a demo, and take notes on what they need
• Proactive — spots problems early, moves things forward, doesn't wait to be told
• Fluent English

Nice-to-have:

• Frontend: JavaScript, Ajax
• DevOps, CI/CD, Azure deployments

Why this role:

• Fully remote
• Competitive salary, performance bonuses, with long-term contract potential
• Real ownership — you shape both the technical direction and what gets built
• Work with a modern financial tech stack
• Small team, real impact — no layers, no waiting for approval

Role:

Our platform connects businesses with financial institutions in real-time — helping them manage cash flow and access financial data without the usual friction.

You will not just maintain what exists — you will help grow the product. That means shaping what gets built next, working with customers to understand what they actually need, and turning that into features that make a real difference. You will have a say in the roadmap.

On the technical side, you will lead the team — making architectural decisions, reviewing code, handling deployments, and making sure what goes to production is solid. We don't have a dedicated QA, so quality is on the team.

Day to day you will also keep things moving — running standups, planning work, talking to customers, showing demos, and writing up what needs to be built clearly enough that the team can just get on with it.

This is a hands-on role. You will write code, not just review it. But more than that — you will be the person who owns the product technically and helps it grow.
