Gravira Group

Luck doesn’t happen. It accumulates.

At Gravira Group, we believe exceptional results are built through thousands of smart decisions, fast experiments and people who care enough to ask one more question.

That’s what Gravity of Luck means to us.

We’re building one of the fastest-growing iGaming products in Tier-1 markets, and we’re looking for a hands-on Media Buyer who knows how to turn creative testing, data and disciplined execution into profitable growth.

About Gravira Group

Gravira Group is a fast-growing international iGaming company focused on Tier-1 markets.

We build and scale our own products by combining Product, Acquisition, CRM, Payments, Engineering and Analytics into one high-performance system.

We move fast.

We make decisions based on data.

We trust ownership over bureaucracy.

Our main acquisition focus is Facebook (Meta) and Canada, and we’re looking for a Media Buyer who can take ownership of paid acquisition and scale profitable traffic.

Why this role exists

Paid acquisition is one of the key growth engines of the business.

Scaling isn’t simply about increasing budgets.

It’s about finding the right combination of angle, creative, funnel, traffic source and GEO, then knowing when to scale, when to optimize and when to stop.

Your mission is to turn testing and data into profitable acquisition across Tier-1 markets, with a strong focus on Canada.

You’ll own campaigns from planning and launch through optimization and scaling, with direct impact on acquisition performance and revenue.

What You’ll Own

• Planning and executing paid acquisition campaigns across Facebook (Meta) for Gambling in a policy-compliant way.
• Working across iOS, PWA and Android flows.
• Building, testing and scaling bundles including angles, creatives, pre-landers, landers and funnels.
• Optimizing campaigns against CPA/FTD, ROAS, CTR, CVR and payback targets.
• Running structured A/B and multivariate testing.
• Managing and pacing $30k+ monthly budgets with clear caps, rules and daily P&L control.
• Setting up and maintaining tracking in Keitaro and/or Binom.
• Ensuring clean attribution and reliable campaign reporting.
• Analysing cohorts and GEO/channel performance.
• Making daily scale/kill decisions based on data.
• Working closely with Design on static, motion and UGC creatives.
• Collaborating with CRM on retargeting initiatives.
• Working with Product and BI on dashboards, reporting and performance insights.
• Sourcing and validating new traffic sources, placements and whitelists.

• Negotiating with traffic source representatives where relevant.

   

What Success Looks Like

Six months after joining Gravira Group:

• Paid acquisition is scaling profitably across Tier-1 markets.
• Canada is delivering consistent and scalable acquisition performance.
• Campaign budgets are managed with clear discipline and daily P&L visibility.
• New creative angles, bundles and funnels are being tested consistently.
• Winning combinations are identified and scaled quickly.
• Underperforming campaigns are identified and stopped before they create unnecessary losses.
• Tracking and attribution remain clean and reliable.
• Campaign decisions are driven by data, cohort performance and clear profitability targets.

• The acquisition team has a repeatable process for testing, validating and scaling new opportunities.

   

We’re Looking For Someone Who

• Has 2+ years of media buying experience in the Gambling vertical, primarily with Facebook (Meta).
• Has proven experience launching and optimizing iOS, PWA and Android apps or flows.
• Has recent successful campaigns from the last 2–3 months that you can walk us through — from goal and setup to results.
• Has hands-on Tier-1 experience, with Canada (CA) being a must.
• Has practical experience with Keitaro and/or Binom.
• Is comfortable managing $30k+ monthly budgets with disciplined testing and daily optimization.
• Can consistently find and generate new bundles across angles, creatives and flows.
• Understands performance metrics and can make fast scale/kill decisions.
• Takes ownership of results and can work independently.
• Is reliable, execution-focused and comfortable working at speed.

• Communicates clearly in written and spoken English.

   

Nice to Have

• Experience with allowlists, policy approvals and responsible-gaming messaging for Tier-1 markets.
• Familiarity with spy tools such as Adplexity or Anstrex.
• Experience working with UGC and motion creative pipelines.
• Experience with GA4, Looker, Tableau or advanced spreadsheet analysis.

• Strong understanding of creative testing and performance-driven production workflows.

   

Why Gravira Group

This is a role for someone who likes to see the direct connection between their decisions and the numbers.

You’ll have direct access to decision-makers and short feedback loops.

You won’t need to wait weeks to test an idea.

You’ll have autonomy to launch, analyse, optimize and scale — with clear responsibility for the results.

We value:

Ownership over micromanagement.

Speed over unnecessary processes.

Testing over assumptions.

Profitability over vanity metrics.

And people who are willing to take responsibility for what happens after they press Launch.

Build Gravity of Luck

At Gravira Group, luck isn’t random.

It’s the result of curiosity.

Of ownership.

Of speed.

Of hundreds of tests, decisions and optimizations that compound over time.

If you know how to turn a new angle into a winning bundle, a winning bundle into scalable traffic, and data into the next decision, you’ll feel at home here.

Build Gravity of Luck with us.

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:

About the role

We are looking for a Senior Technical Writer to design and automate AI-driven software documentation for end users, developers, and system integrators.

The mandatory requirements are 4+ years of technical writing experience, prompt engineering and AI tools, APIs, systems and data models, Git, YAML, or Markdown, and an upper-intermediate English level.

Must haves

• 4+ years of technical writing experience, with demonstrated expertise in software documentation (SaaS, cloud platforms, or developer-focused content).
• Deep familiarity with prompt engineering and ability to design effective prompts, configure AI tools, and iterate based on output quality to achieve consistent documentation.
• Strong understanding of documentation architecture and information design. Ability to analyze different documentation types and design patterns that scale.
• Technical comfort with APIs, event streaming, batch processing, system architecture, and data models. Ability to understand complex concepts and write documentation that captures them accurately.
• Proficiency with Markdown, YAML, Git, and version-controlled workflows. Comfortable in code editors and command-line environments.
• Strong written and verbal communication skills, with an ability to write clear, user-centered documentation and communicate technical concepts to diverse audiences.
• Attention to detail and excellent organizational skills with the ability to manage multiple priorities and maintain consistency across documentation systems.
• Problem-solving mindset with ability to think critically about processes and advocate for improvements to documentation systems and workflows.
• Experience in fast-paced, cross-functional product environments with the ability to adapt to changing priorities.
• Bachelor's degree in computer science, English, or a related field, or equivalent work experience.

Nice to haves

What you will do

• Partner with product, engineering, and operations teams to understand documentation needs and user workflows, then design documentation architecture and automation patterns that serve multiple audiences – end users, developers, and system integrators.
• Establish documentation standards and build governance and quality gates directly into the automation system to ensure all generated documentation – user guides, API documentation, integration guides, in-product help, and release notes – maintains consistency and user value.
• Build and refine prompt templates, style guides, and content models that enable developers and writers to generate consistent, high-quality documentation at scale.
• Write, edit, and review documentation to model excellence, validate automation output quality, and identify patterns that strengthen prompts and templates.
• Measure documentation impact using analytics and user feedback to identify gaps and inform improvements to the automation system, content strategy, and documentation approach.
• Document all systems, configurations, prompts, and decision logic thoroughly so the team can maintain, evolve, and improve the automation system independently.
