What we’re looking for

• 1+ year of commercial experience shipping production software as a Full-Stack Engineer
• Strong Node.js and React skills
• Experience working with and maintaining a large existing codebase

Ready to build, improve and ship? Let’s talk!

Location: 100% remote (EMEA, CET±2), with team gatherings in person a few times a year
Hours: Full-time, 40 hours per week
Pay: €60.000 to €90.000 annually, adjusted by experience and location

At Miaplaza, we build homeschool platforms that kids aged 4–18 actually want to use — Miacademy, MiaPrep, and our Online High School are serving over 150.000 students today. Our product foundations are strong. What we want next is a step change in how our products feel: more expressive illustration, more purposeful motion, more moments of craft that turn a lesson into something a kid remembers.

We're hiring a Senior Product Designer whose craft anchor is illustration and motion. Our design team is small and senior, five designers when you join, and each brings a distinct strength: brand, design systems, research, and now yours

The role

You'd own product design for the student learning experience end-to-end: from problem framing through delivery, in a Product Trio with a PM and EM who have strong opinions and expect yours. This is product work with real trade-offs — pedagogical, technical, and business — and you're accountable for how it lands, not just how it looks.

Beyond Curriculum, you'd set the illustration and motion bar for all of Miaplaza: the standards, motion principles, and character direction that the other designers and the design system build from.

A defining part of the role is art-directing AI-assisted production. You'd build the prompts, references, and review process that let a small team produce quality illustration and motion at a scale hand-crafting alone can't reach. We don't expect you to know every current tool — we expect the taste and judgment to direct output rather than accept defaults.

You'd report to the Head of UX, with regular 1:1s covering craft, product, and career growth. The direction is upward: deeper craft leadership, cross-product influence, or both.

You must have all of these to be considered:

• A portfolio of shipped digital product work — not only concepts or standalone pieces
• At least 2 years working inside a product team, collaborating with PMs and engineers
• Strong illustration or motion skills, with at least 1 year focused on either as a primary craft
• Proficiency in Figma
• Some experience directing or guiding visual work produced by others — freelancers, junior designers, or AI tools

You’ll stand out if you also have:

• Deep motion skills in product contexts: interactions, transitions, onboarding, character animation
• Experience using AI image or motion tools as production accelerators
• Confidence running your own usability research, not just receiving findings
• Multi-brand or education-focused design experience
• Accessibility practice, especially for neurodivergent audiences

This probably isn’t right for you if:

• Your work hasn't yet lived inside a live product with real constraints
• You prefer well-scoped tasks over shaping ambiguous problems
• You see AI tools as either a threat to craft or a shortcut around it

Our hiring process

As a remote company, we receive a large number of applicants, and finding the best fit for this role is our top priority — that’s why our process is longer than usual. At every stage, we try to be respectful of your time and grateful you’re spending it with us.

1. Application and eligibility check — work authorization, timezone, availability
2. Async assessment — 12 scenario-based, multiple-choice questions (~30 min) + when qualifying; 3 open questions (max. 45 min)
   1. If you pass the multiple choice section, you will be asked to complete 3 open written questions (max. 45 min)
3. Portfolio review — the design team will review your best work and thinking
4. Behavioral interview — a conversation with our People team about how you work
5. Take-home design task — ~60 minutes, scoped for this role, AI tools encouraged
6. Hiring team interview — with a design team member and the Head of UX
7. Skip-level conversation — with executive leadership
8. Reference checks

We give honest, timely feedback at every step. Job searches are hard; we don't want to make yours harder.

Compensation and setup

The pay range for this role is €60,000 - 90,000. Miaplaza’s compensation philosophy ensures equity and competitiveness while considering regional differences in labor costs. Placement within a range is determined based on factors such as demonstrated skills, internal equity, and local labor market rates for the candidate’s geographic area.

Miaplaza is a growing, self-funded EdTech company. We're an equal opportunity employer and welcome applicants from all backgrounds. If you need accommodations at any point in the process, just let us know.

Codebridge is looking for an Applied AI Engineer to build the AI functionality of a corporate learning platform end to end. Agents — planning, tool use, acting across the product — are the core, surrounded by retrieval, content generation, and labs. Everything is model-agnostic across Claude, OpenAI, and Gemini. 

     Responsibilities

• Design and ship agents — the core of the role: planning, tool use, memory, and guardrails, orchestrated with LangChain/LangGraph, exposed via MCP where it fits, running behind a provider-abstraction layer with model routing and cost control
• Build product features end to end — from the front end through backend services to the model call in the cloud
• Set up and tune retrieval: ingestion, chunking, retrieval quality, reranking, and grounded generation with citations
• Evolve the content-generation pipeline: grounded generation from ingested sources, structured outputs that survive provider differences, and accuracy checks that keep generated material true to source
• Develop hands-on lab environments in a sandboxed execution platform: mock APIs, auto-verification harnesses that grade learner work, and managed multi-provider model access with per-user budgets
• Take charge of evaluation infrastructure: task datasets, deterministic and model-based graders, regression suites, and cross-provider benchmarks

     Requirements

• 4+ years in software engineering, with production systems you can walk through end to end
• 1+ years shipping production LLM applications — agents, tool use, retrieval — with hands-on work across at least two of the three major platforms (Anthropic, OpenAI, Google)
• Depth in agent development: tool use, memory, multi-step orchestration, and MCP — you've built and debugged MCP servers, not just consumed them
• Claude Code as a daily working tool, plus working fluency with the OpenAI API and Gemini — or a demonstrated ability to get there fast, since the abstractions matter more than any single SDK
• Evaluation fluency: task datasets, deterministic and model-based graders, regression suites. "I tested it manually and it looked fine" is an unfinished sentence
• Solid Python for LLM tooling, with experience in LangChain/LangGraph or an equivalent orchestration framework
• Comfort with sandboxed cloud execution environments, CI, and API security basics
• Clear technical communication — you can review someone else's work rigorously and kindly, and explain a model limitation to a non-engineer without jargon
• A responsible, outcomes-focused mindset
• Advanced English or higher
  
  Nice to Have: 
• Experience with TypeScript/Node/React 
• Provider certifications (Anthropic, OpenAI, or Google Cloud AI) or demonstrable equivalent depth 
• Experience with learning platforms, developer education, or technical enablement 
• Experience with LLM gateway/routing layers, structured-output schemas across providers, or multi-model evaluation tooling 
• Public evidence of technical judgment: open-source contributions, technical writing, or talks 

     What we offer

• Technical Ownership: You own the AI architecture and the standards behind it
• Modern AI Work: Agents, retrieval and evaluation as the everyday job, not a side experiment
• Collaborative Environment: A team that values partnership, creativity, and mutual respect
• Flexible Work: Work remotely from the comfort of your home or join us in our modern Kyiv office
• Generous Time Off: 20 paid vacation days + 15 sick leave days annually
• Professional Growth: Compensation for courses, certifications, and learning resources
• Cutting-Edge Tools: Access to premium AI tools (Cursor Pro, Claude Code, GitHub Copilot, etc.)

• HR&Technical Interview

About Realityjam

Realityjam (Virtual Reality Jam Ltd) is a UK-based game development studio and multiplayer game development platform on a mission to reimagine how games are made and how careers in the industry are built.

Our Industry Access Program is a two-year pathway that empowers the next generation of coders, artists, and creators to forge real careers in game development — without traditional education barriers. Learners work on live MMO titles from day one, earning credits on published games while developing professional-grade skills in a fully remote, community-driven environment.

We are now looking for an experienced Technical Artist, 3D Artist, or Unity Generalist with experience using Blender and Unity as a trainer to join our growing pool of specialist trainers.
 

The Role

As a Game Development Trainer, you will deliver approximately two days of structured, hands-on training per week to cohorts of aspiring game developers and technical artists working through the Realityjam Industry Access Program, during UK business hours. The exact hours are somewhat flexible, the time required can be structured around other commitments.

Your sessions will blend practical instruction with real-world context. Learners are actively contributing to live game projects via our education program, so your teaching will be grounded in production-grade workflows rather than abstract theory. You will report to the Programme Lead and work collaboratively with the wider training team to ensure session content aligns with the programme's curriculum and learning outcomes.

This is a freelance, remote role ideally suited to a working games professional with some experience as an educator who wants to share their expertise, shape the next generation of technical artists, and be part of a movement redefining game development careers.
 

Key Responsibilities
 

Training Delivery
 

• Deliver one structured training day per week (approx 8 hours) covering technical art and 3D modelling fundamentals and advanced workflows.
• Educational content and learning materials have been planned and produced by our team, you'll be required to deliver this content using our own bespoke learning environment.
• Deliver live, remote-first sessions that are practical, engaging, and rooted in industry-standard production pipelines.
• Set and assess learner exercises, portfolio tasks, and project milestones aligned with programme learning outcomes.
• Adapt session content to the varying skill levels and backgrounds of learners across the three programme pathways (Scion Foundation, Published Game, and 2 Years Experience tracks).
   

Learner Support
 

• Provide feedback and guidance to learners on their work, helping them build portfolios that reflect genuine production quality.
• Flag learner progress, attendance, or wellbeing concerns to the Programme Lead in a timely manner.
• Participate in occasional programme team check-ins and trainer briefings as required.
   

Primary Training Tools
 

Training sessions will be built around the following industry-standard tools, proficiency in both is required; 
 

• Unity Engine

Scene assembly, asset import pipelines, prefab workflows, materials and shaders, lighting, LOD, and optimisation for real-time game environments.
 

• Blender

3D modelling (hard surface and organic), UV unwrapping, retopology, rigging fundamentals, baking, and FBX/glTF export for game engines.

Desirable Skills & Experience
 

• Demonstrable professional experience as a Technical Artist or 3D Artist within the games industry, with a strong portfolio of shipped or in-development work.
• Advanced proficiency in Blender, Substance Painter, and Unity — comfortable teaching each tool at a production level.
• Deep understanding of real-time art pipelines: polygon budgets, texture atlasing, normal map workflows, PBR materials, and performance optimisation.
• Ability to communicate complex technical concepts clearly to learners at different skill levels.
• Self-directed and reliable — able to plan and deliver sessions with minimal oversight in a remote environment.
• Comfortable working asynchronously and communicating via Discord and remote collaboration tools.
• Previous experience in training, mentoring, or education — formal or informal.
• Familiarity with MMO or online game art pipelines and the specific constraints they involve.
• Experience with Unity's Universal Render Pipeline (URP) or High Definition Render Pipeline (HDRP).
• Knowledge of shader graph, VFX graph, or procedural material creation workflows.
• Interest in game development access, diversity, or community-building initiatives.
