Nice to Have

• Experience with vector databases or embedding search (e.g., MongoDB Atlas Vector Search, pgvector, Pinecone).
• Familiarity with agent frameworks, the Model Context Protocol (MCP) or the Claude Agent SDK.
• Reading-level familiarity with C# / .NET and Angular / TypeScript, enough to trace how your services are called.
• MLOps experience: Docker, CI/CD pipelines, model versioning (MLflow or similar) and cloud deployment (Azure or AWS).
• Prior work on a multi-tenant B2B SaaS product.
• NLP work on unstructured business text such as documents, emails or research content.
• Understanding of data privacy and security practices for customer data used in AI features.

About the project:
A connected beauty technology company building a smart mirror (in-store, running proprietary software) and a mobile app on iOS and Android. Behind both sits the company’s intelligence layer, which includes an AI Skin Analyzer, a virtual makeup artist, and a routine builder. Skin analysis already runs on proprietary models — the next step is live, realistic rendering on a real face, on a phone and on a wall-mounted mirror.

The role:
This role has more ownership than most: there is no existing face-rendering team to join, and you’ll set its standards. It also has more physical hardware than most software roles — you’ll work with a real Smart Mirror and real devices, and some of the hardest problems (light, skin, cameras) only show up there.

We are hiring an engineer to own the real-time face rendering behind three products:

• Treatment Preview — previews cosmetic treatments on the user’s own face (wrinkle smoothing and brow lift for neurotoxin-style treatments, lip and cheek volume for dermal fillers);
• AR product try-on — letting a shopper see a specific lipstick, blush, or foundation shade from the catalog on their own face, live, with accurate color matching;
• Guided makeup looks — walking a user step by step through a complete makeup look rendered live on their own face, built on the same shared engine.

This is a hands-on senior IC role. You’ll be the person who knows how the face engine works, building it rather than integrating someone else’s. The Flutter app team builds the screens around your work, and ML engineers own the analysis models. You own everything between the camera frame and the pixels on screen.

What you’ll work on:

• Build a shared face-rendering engine for Android and iOS: camera frames in, face tracking, region masks and warps, GPU shading, and frames out to a Flutter texture;
• Build Treatment Preview: smoothing, warps, and volume effects rendered behind a Flutter texture, guided by a wrinkle mask that updates slower than the frame rate, keeping effects stable on a moving face;
• Build realistic makeup rendering: lips, cheeks, base, eyes, with finishes (matte, satin, gloss, shimmer) that respond to light and work across the full range of skin tones;
• Connect the product catalog to the face: a pipeline that turns a product’s shade and finish into rendering parameters, scalable to thousands of products;
• Build multi-step guided makeup looks on the new engine;
• Optimize for real hardware: modern iPhones, mid-range Android phones, and a Smart Mirror running a 4K USB camera all day in-store;
• Measure quality: stability, color accuracy against real product swatches, and failure rates by skin tone, lighting, and face angle.

Tech stack:

• Rendering: OpenGL ES 2.0/3.0 (GLSL) on Android, Metal on iOS;
• Face geometry: ML Kit face detection for capture; dense face landmarks and blendshapes for rendering;
• Image processing: C++ with OpenCV;
• Native: Kotlin and C++ on Android, Swift on iOS;
• App: Flutter (Dart) with Bloc — you’ll write the platform-channel and texture boundary, and the app team writes the UI;
• Test devices: iPhone, Galaxy-class Android, and the company’s Smart Mirror.

Requirements:

• 5+ years of professional software engineering, including substantial real-time graphics work — you have written and shipped GPU shaders (GLSL, Metal, HLSL, or similar) in a product that ran at frame rate on real devices. This is the single most important requirement;
• Hands-on work with face tracking or face geometry: landmarks, face meshes, UV mapping, region masks, warps, or morphs (AR filters, virtual try-on, avatars, and face retouching all count);
• Native mobile development on Android (Kotlin/Java, NDK/C++) or iOS (Swift/Objective-C), with willingness to work on both;
• Experience putting ML models in a real-time pipeline, designing rendering around the model being the slow part;
• Practical grasp of color and image processing: color spaces and gamma, blending, frequency separation, filtering;
• An eye for realism and the discipline to measure it;
• Comfort working in an existing codebase;
• Clear English, spoken and written, with a working style that holds up across time zones.

Will be a plus:

• Shipped a virtual makeup try-on, beauty filter, or face-retouching product;
• Flutter external textures or platform views, or embedding native rendering in any cross-platform UI framework;
• Training or fine-tuning segmentation models (face parsing, lips, skin) and building the datasets behind them;
• Physically based shading, or measuring color from real product swatches;
• Experience with inclusive evaluation across Fitzpatrick skin types, lighting conditions, and ages;
• Low-level Android camera work (Camera2, UVC/external cameras) or embedded devices;
• Knowledge of aesthetic medicine, or experience building consumer features near medical claims.

Working hours:
Our engineering team works in Central European time, and our leadership team is on the US East Coast. Your working day ends at 20:00 CET, and dependable availability through the afternoon until then is a firm requirement of this role. That’s the window where your day overlaps with the US morning, when decisions get made, priorities get set, and cross-team questions get answered.

Not required — please apply anyway if you don’t have these:

• Beauty or cosmetics domain knowledge;
• Flutter or Dart experience;
• A computer science or graphics degree.

We offer:

• Remote work;
• Legal support;
• Paid sick leaves, vacations, and public holidays;
• Medical insurance;
• Free English classes.

Binariks is looking for a Data & AI Engineer (Semantic Layer) to design the knowledge that AI agents reason over. This covers how drugs, payers, coverage rules, prescribers and patient journeys connect, and the shared vocabulary every agent relies on.

The project is an emerging AI decision-intelligence platform for pharmaceutical commercial teams, developed for a US healthcare data and analytics company. It turns daily specialty-pharmacy, hub, payer and clinical data into AI-generated recommendations that show why they were made and who acts on them, then measures whether they worked. The role will join a senior Binariks team working alongside the client's product and engineering teams on AWS.

What we are looking for:

• 5+ years in data engineering, analytics engineering, or solutions engineering, with a solid track record in client-facing environments
• Experience integrating data/semantic context with LLM applications (RAG, GraphRAG, metadata-driven retrieval, or structured outputs) using Python
• Deep expertise in conceptual, logical, and physical data modelling - spanning ER, dimensional, and canonical models, with the ability to map complex business concepts directly to clean data structures
• Hands-on experience with modern data platforms: strong SQL, hands-on experience with AWS or GCP (AWS preferred), and working knowledge of Databricks (Delta Lake, Unity Catalog)
• Experience with data catalog and metadata management with tools such as DataHub, Collibra, Alation, Unity Catalog, Dataplex or Glue, including business glossaries and lineage
• Strong interpersonal skills to facilitate discovery workshops, translate domain jargon into robust technical designs, and articulate trade-offs clearly to non-technical stakeholders.
• Working proficiency in English (B2+)
• High comfort navigating ambiguity, rapid context-switching, and operating embedded directly within client organizations

Your Responsibilities:
 

• Design semantic models, business glossaries, and domain taxonomies to capture complex business logic, utilizing ontology standards (such as RDF/OWL or graph models) where applicable
• Implement semantic models (business entities, metric definitions) directly within Databricks Unity Catalog
• Design the foundational semantic contracts for AI agents (shared vocabulary, entity IDs, permission models, context scoping)
• Integrate knowledge graphs with LLM applications (implementing GraphRAG and semantic context retrieval)
• Build, automate, and refresh graph structures from underlying relational and lakehouse data sources
• Manage graph quality through validation, version control, lineage tracking, provenance, and data governance
• Facilitate discovery sessions with domain SMEs to capture business terms, logic, rules, and relationship mappings

Will Be a Plus:

• Practical background with OWL, RDF, SKOS, SHACL, or Protégé
• Experience building and querying graph databases (Neo4j, AWS Neptune, Stardog, GraphDB) via Cypher or SPARQL
• Hands-on work with GraphRAG
• Familiarity with regulated domain standards such as FHIR (Healthcare) or ACORD (Insurance)

RankHouse is a link-building agency specializing in guest posts and link insertions, with a strong focus on the iGaming industry.

We help businesses strengthen their online presence through relevant publisher placements, managing the entire process from website research and negotiations to content placement and publication.

 

We're looking for an experienced B2B Sales Partner who already has an established professional network in iGaming and is interested in turning those connections into long-term business opportunities.
 

What You'll Do

• Identify and approach potential clients through your existing professional network.
• Connect with decision-makers at iGaming operators, casino and sportsbook providers, and SEO or digital marketing teams.
• Manage the full sales cycle, from initial conversations and identifying client needs to negotiating and closing deals.
• Build and maintain long-term relationships with your clients.
• Generate repeat orders, identify upselling opportunities, and grow existing accounts.
• Collaborate with the RankHouse team on pricing, proposals, and service delivery.
   

What We're Looking For

• Proven experience in B2B sales or business development within the iGaming industry.
• An established network of relevant professional contacts, particularly among SEO Managers, Heads of SEO, CMOs, Marketing Directors, and other decision-makers.
• Experience independently negotiating and closing B2B deals.
• Strong communication, relationship-building, and negotiation skills.
• Ability to identify client needs and develop long-term commercial relationships.

Experience selling SEO, link-building, digital PR, or related marketing services would be a strong advantage.
 

Important: We're looking for someone who can bring relevant industry relationships and close deals, not someone focused solely on cold lead generation.
 

What We Offer

• Commission on new sales: Earn commission for every successfully closed and paid order.
• Recurring commissions: Continue earning from repeat orders generated by your assigned clients.
• Higher earning potential: Additional rewards for higher-margin deals and growing client accounts.
• Flexible cooperation: Work remotely, manage your own schedule, and combine this opportunity with other professional activities.
• Operational support: RankHouse handles publisher research, negotiations, placements, and order fulfillment, allowing you to focus on sales and client relationships.
• Long-term opportunity: Build and develop your own client portfolio with ongoing earning potential.
   

Commission rates and commercial terms are discussed individually based on experience, responsibilities, and the cooperation model.

Earning potential: $1,500–3,000+ per month (commission-based).

No fixed salary. Your earnings depend on successfully closed deals, repeat orders, and account growth. Higher-margin sales offer additional commission opportunities.
