Jobs

The Slot Frontend Engineer is the slot-client authority across Whimsy's slot-development engagements. The role builds and maintains the slot-game client codebase from scratch and owns it through integration, launch, and live operations.

Technical Constraints

• Language: TypeScript
• Renderer: PixiJS v8
• Animation: Spine-Pixi v8 (skeletal), GSAP (tweening)
• Build tool: Vite
• HTTP client: Axios
• Architecture: strict 5-layer separation + typed HFSM at gameplay layer
• Platform integration: third-party slot SDK via pluggable BackendAdapter only
• Regulatory model: jurisdiction-aware client behaviour via configuration (no code rewrites per market)
• Version control: Git
• Target platforms: modern mobile browsers (iOS Safari, Android Chrome) + desktop browsers in use
  
  Responsibilities
• Own the slot-client codebase.
• Own the typed HFSM modelling the slot spin lifecycle, including free spins, bonus rounds, and error / recovery transitions.
• Own the offline mocked backend used for development, QA.
• Own jurisdiction-aware compliance UI: a single client able to satisfy the rule set of different markets under audit without per-market code forks.
• Own session recovery and reconnection behaviour for mid-spin, mid-free-spins, and mid-bonus states.
• Own client-side performance budgets and the asset, atlas, and texture-memory strategy.
• Author and maintain frontend technical documentation: layer contract, HFSM state and transition diagrams, asset manifests, jurisdiction-profile schema.
• Actively use and document the use of AI tools (ChatGPT, Gemini, Claude) for scaffolding, refactor proposals, and documentation. Document outcomes alongside prompts so the workflow is reproducible by the team.

Requirements

• Strict layered architecture: Presentation / HFSM / Domain / Network / Platform; cross-layer access is Non-Compliance.
• Typed HFSM for slot lifecycle (idle, bet, spin request, etc.).
• Robust session recovery: correct resume mid-spin, mid-free-spins, mid-bonus without state inconsistency.
• Full externalisation of game data: paytables, reel strips, RTP, jurisdiction profiles, feature flags must be server/config-driven.
• PixiJS v8 slot rendering for mobile/desktop within performance budgets, with no visual artifacts during reels, cascades, or bonus flows.
• Spine-Pixi v8 expertise for skeletal animations (symbols, characters, bonus presenters), including layered states and event hooks.
• GSAP orchestration for complex sequences: spin-stop, win reveal, cascades, jackpots, bonus entries.
• Tunable animation parameters (easing, timing, anticipation, win effects).
• Asset strategy: atlases, texture packing, and memory-optimized loading for mobile draw-call and RAM constraints.
• Server-authoritative model: client never controls outcome, RNG, balance, or probability.
• Jurisdiction rules must be configuration-based, not code changes per market.
• No secrets/keys/SDK credentials in source, fixtures, or Git history.
• Performance targets: 60 FPS mid-tier mobile, 30 FPS minimum on low-end devices.
• Defined bundle-size and cold-load budgets under poor network conditions.
• Profiling expertise for rendering, animation, and runtime bottlenecks.
• Knowledge of GPU/render optimization: atlases, sprite sheets, render textures, instancing, and their trade-offs.
• Network resilience: timeouts, exponential backoff, idempotent retries (BackendAdapter), deterministic behaviour under packet loss, mid-spin disconnect/reconnect.
• Observability: structured client logging with correlation IDs for spin-level backend tracing.

Nice to have

• Experience with regulated slot / iGaming frontend
• Live ops: jackpots, tournaments, campaigns, A/B tests
• Localization: RTL, CJK support
• Remote config + A/B testing for mechanics and UX
• CI/CD pipelines (lint, type-check, tests, build, deploy, environments)
• Strong Git discipline (atomic commits, PR hygiene)
• Technical documentation: layer contracts, HFSM diagrams, runbooks (English)

What We Offer

• Greenfield backend - you design the architecture, choose the stack, own the outcome
• Small focused team: no bureaucracy, direct access to decision-makers
• Fully remote, async-friendly
• Competitive compensation, discussed individually
• A product that ships - not an endless pre-production

Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/

About the role

At RubyLabs, we’re seeking a senior AI Engineer (Node.js / Next.js / TypeScript) to shape our AI infrastructure and drive production-ready LLM experiences. You’ll work in a modern stack, making data-driven decisions around model performance, reliability, and cost.

You’ll own advanced prompt systems, structured outputs, and complex LLM workflows using LangChain or LlamaIndex. Observability, debugging, and evaluation are core to the role, leveraging Langfuse and AI gateways like OpenRouter to continuously improve model quality and operational efficiency. You’ll take full ownership of key AI features from experimentation to live production.

Key Responsibilities

• Advanced Prompt Engineering: Designing complex, dynamic prompt templates with conditional logic and efficiently reusing information and context within prompts to maximize generation quality and reasoning.
• Structured Outputs & Schemas: Implementing various response schemes (JSON mode, function calling, Zod/JSON schemas) to ensure AI outputs are predictable and ready for seamless integration into application logic.
• Prompt Engineering & Evaluations: Building robust evaluation pipelines and using Langfuse to collect feedback and score the quality of responses in real time.
• Tracing & Debugging: Performing deep debugging of complex LLM chains using Langfuse traces to identify bottlenecks and optimize for cost, latency, and context window usage.
• AI A/B Testing: Running systematic experiments across different models via OpenRouter (e.g., comparing Claude 3.5 Sonnet vs. GPT-4o) and analyzing results based on quantitative metrics.
• Data-Driven Decisions: Making deployment decisions for new prompts or models strictly based on quantitative benchmarks and trace data, rather than intuition.
• Output Scoring & Analysis: Developing scoring systems to analyze the “Problem → Solution” chain and identify root causes of hallucinations or logic errors using Langfuse analytics.
• Model Performance & Fine-Tuning: Regularly re-evaluating model performance as new architectures emerge and performing fine-tuning when necessary to meet specific domain requirements.

Qualifications

• Node.js & Next.js: Deep knowledge of the stack to build reliable services and handle complex LLM-generated data.
• Dynamic Prompting Skills: Proven experience in building prompts where content is highly dependent on input variables and context injection.
• OpenRouter Experience: Experience working with unified APIs, managing rate limits, and selecting the most cost-effective models for specific tasks.
• Langfuse (or similar): Understanding of LLM observability principles — setting up tracing, creating test datasets, and integrating scoring systems.
• Evaluation Methodology: Experience with frameworks like RAGAS or building custom “LLM-as-a-judge” systems.
• Analytical Mindset: Ability to transform raw generation logs into actionable business metrics and technical insights.
• Iterative Mindset: Focus on continuous product improvement through constant feedback loops.

Nice to have

• Fine-Tuning: Practical experience in fine-tuning models for specific domain tasks or JSON compliance.
• RAG Architecture: Understanding how to build and optimize Retrieval-Augmented Generation systems, including indexing, retrieval, and re-ranking.
• Python: Basic knowledge for working with data science scripts or AI evaluation libraries.

• Deep knowledge of B2B outbound: cold email, LinkedIn prospecting, email deliverability, AI in sales
• Ability to go deep on any outbound topic in 1–2 weeks and present it credibly
• Strong communication and stakeholder management skills — you coordinate designers, partners, marketing, and sales independently
• Self-starter with a founder mentality — you see a gap and fix it without being asked

Will be a plus:

• Experience running or speaking at webinars, workshops, or online events
