Astrix builds conversational AI simulations that help organisations develop and measure human skills like leadership, communication, and decision-making — skills that traditional training struggles to evaluate.

We work with enterprise clients, consultancies, and institutions to create realistic, voice-based simulations powered by agentic AI, real-time audio processing, and analytics. Our platform sits at the intersection of AI, product, and human behaviour.

We’re now looking for a mid-level full-stack developer to join our existing team of data scientists and engineers and help scale the platform.

The Role

You’ll work across the stack, owning meaningful parts of the product end-to-end — from real-time audio capture through to dashboards and platform integrations.

This is not a ticket-factory role. You’ll be trusted to work independently, deliver against milestones, and collaborate closely with the founding team on product decisions.

• Scaling the Astrix platform for enterprise use
• Building and maintaining cross-platform desktop functionality (macOS & Windows)
• Real-time audio capture, streaming, and transcription pipelines
• Integrations with enterprise systems (e.g. SAP, SuccessFactors, LMSs)
• Improving performance, reliability, and security
• AI evaluation flows, analytics, and dashboards
• Iterating on product UX alongside the founders
  
   

Required Experience

• Full-stack experience delivering MVPs end-to-end
• Experience with Electron for cross-platform desktop apps
• Real-time audio capture and processing
• WebSocket-based streaming systems
• Integration with real-time speech-to-text APIs (streaming transcription)
• Experience with Cloudflare Workers
• Event-based data modelling and database design (session + event ingestion)
• React experience for integrating with the core platform
• Comfortable working independently with milestone-based delivery

Bonus (Nice to Have)

• Experience with real-time transcription (STT)
• Cloudflare Durable Objects or similar stateful real-time systems
• Audio/video streaming formats (WebM, Opus, PCM)
• Dashboard or analytics UI experience
• Startup or early-stage product experience
• Familiarity with Clerk or similar authentication providers

Working Model

• Fully remote
• CET timezone overlap preferred
• Full-time contractor
• Flexible start date (March ideal)

Compensation & Upside

• Competitive salary
• Opportunity to work deeply with:
  • Agentic AI
  • Conversational AI
  • Real-time systems used by enterprise clients

Who Thrives at Astrix

The kind of engineer who thrives here is someone who:

• Is a self-starter and doesn’t need micromanagement
• Is disciplined about milestones and deadlines
• Communicates clearly and proactively
• Is comfortable owning problems end-to-end
• Enjoys building real products used by real people

How to Apply

Send us:

• A short intro about yourself
• Your CV / LinkedIn
• (Optional but appreciated) examples of products, repos, or systems you’ve owned

What You’ll Do: 

• Architect and build internal tools to improve developer velocity and code quality 
• Own infrastructure solutions such as production testing and performance tooling
• Take projects from ideation through design, implementation, and production
• Use AI daily for coding, testing, design, and technical decisions
• Work with modern full-stack technologies and industry-leading tools 
• Collaborate closely with experienced engineers on high-impact projects 

• Influence the developer experience across the company

   

At Wix, we’re all about the flexibility of a hybrid setup — giving you the option to collaborate in the office when needed while also staying connected remotely.
We’re looking for Ukraine-based talents who can balance their time between in-office and remote engagement with the Wix team. This approach gives you the best of both worlds: flexibility of remote with the added benefit of in-person collaboration when it matters

• Deep expertise in TypeScript, React, and modern build tools (Vite, Next.js, SWC/ESBuild).
• Solid understanding of backend systems (Node.js preferred), including APIs and data flows
• Hands-on use of AI tools in daily development
• Professional-level English communication skills
• End-to-end product development experience (frontend, backend, cloud) is a plus

About the Team

We’re part of Wix’s Frontend Engineering (FED) Guild, serving as the Infrastructure group that empowers every frontend developer at Wix to move faster and deliver higher-quality code. Our mission is to design and maintain impactful tools that boost developer velocity, code quality, and performance.Our team is made up of exceptional developers, passionate engineers, and creative problem-solvers. You’ll work on developer-focused infrastructure - from scalable testing platforms and performance optimization tools to standardization frameworks and AI-driven solutions like automated code migrations and intelligent project bootstrapping.

About Wix

Wix makes it possible for anyone to succeed online. 

Since 2006, we've grown to around 5,300 employees in 22 countries, launched over 40 products, and serve over 299 million users and their visitors worldwide. 

At Wix, we push you to innovate, evolve in non-traditional ways, and collaborate. We operate in small teams that work closely together at a high level. 

Although we're already industry leaders in web creation and business, our work is nowhere near done.  Our goal is to become the main engine of the Internet so we can create a more open web for all.

We're proud to be an equal opportunity company. Wix was built around the idea that everyone has the right to be successful, online. This same vision defines us as a company: creating a work environment where everyone is welcome, and anyone has the right to succeed.

Working Style & Expectations

We are looking for committed, highly motivated professionals who take ownership seriously. This role requires consistent collaboration during U.S. Eastern Time business hours, reliability in scheduling, and strong follow-through. Being on time, prepared, and diligent is essential — this is a senior role on a system that underpins real operations, not an experimental project.

We value people who are excited by hard problems, communicate clearly, and treat commitments as non-negotiable.

1. AI/ML Developer Model Training & Fine Tuning

2. Data Model & Architect

3. Developers Microservices / API  ETL & Integration developement

We are building an end-to-end system that turns unknown physical parts into known, sellable products — automatically. The system ingests parts through vision and sensors, resolves identity using AI and structured knowledge, and publishes those parts into a fully integrated commerce, logistics, and search ecosystem.

This is not a research role. It is a production systems role spanning computer vision, large-scale data ingestion, retrieval systems, cloud infrastructure, and e-commerce integration.

What you will build

• A learning ingestion pipeline that identifies unknown physical parts using images, 3D data, and metadata, and improves continuously through human confirmation
• Vision and retrieval systems using multimodal embeddings and vector search to match parts across large catalogs
• A RAG-based knowledge system that ingests, parses, and normalizes manufacturer PDFs, schematics, and parts manuals into APIs
• Event-driven services that publish identified parts into inventory, commerce, shipping, and ERP workflows
• Search-optimized part representations engineered to be discoverable by Google, analytics systems, and downstream AI models

Why this is hard — and interesting

• Parts are visually similar, worn, incomplete, and inconsistent across manufacturers
• Manufacturer data is fragmented, unstructured, and often only available as PDFs and diagrams
• The system must operate across perception, inference, search, commerce, and logistics — not just ML
• Identification must be probabilistic, explainable, and correctable, while downstream systems require deterministic truth
• The platform must learn continuously without breaking accounting, inventory, or customer trust

This is a real-world intelligence problem, not a model-training exercise.

Technical environment

• Google Cloud Platform (Cloud Run, Compute Engine, GPU instances, Cloud Storage)
• MongoDB Atlas for operational and catalog data
• Vector search and retrieval systems for embeddings and similarity matching
• Event-driven and API-first architecture
• Computer vision, multimodal embeddings, and RAG pipelines in production

Required experience

• Senior-level experience building production AI or data-driven systems end-to-end
• Strong background in computer vision, retrieval systems, or multimodal ML
• Experience designing cloud-native systems on GCP or similar platforms
• Deep Python expertise; comfort owning architecture and trade-offs
• Ability to connect ML outputs to real business systems (commerce, ERP, logistics)

What success looks like

• Unknown parts can be ingested, identified, and published without manual data entry
• Manufacturer documents become structured, queryable knowledge
• Identified parts flow cleanly into e-commerce, search, and fulfillment systems
• The system improves over time without increasing operational risk
