Backend Game Logic Engineer

I’m building a persistent, browser based strategy MMO. The UI is largely in place, I need an experienced backend engineer to implement the core game engine and logic, strictly following a written specification. This is a logic heavy role, not a UI or design role. What you’ll be responsible for You will implement the backend systems that power the game, including: - Colony state and ownership - Resource production, storage caps, and protection - Build / research / training / shipyard queues (time-based, server-authoritative) - Fleet travel, ETA calculation, and recall windows - Deterministic combat resolution (no RNG) - Colonisation, conquest, and hard anti-griefing rules - Technology effects on units, fleets, and travel - APIs consumed by an existing frontend UI The game is fully deterministic: Given the same inputs, outcomes must always be identical. - Non negotiable constraints Please do not apply if any of these are a problem: - No randomness in combat, travel, or production - No “simplifying” mechanics - No redesigning rules or systems - No adding features that are not in the spec This role is implementation, not interpretation. What I’ll provide - A detailed game design document defining all mechanics - Clear formulas for combat, travel, sensors, queues, and tech - An existing frontend UI to integrate against - Fast feedback and decisions (no stakeholder mess) Tech stack - I’m flexible on stack, but you should be comfortable with: - REST or equivalent API design - Relational data modelling - Time based systems (queues, timers, delayed resolution) - Writing automated tests for deterministic logic Please state: - Your preferred backend stack - How you would test deterministic systems - Deliverables (initial milestone) As a first milestone, I expect: Backend logic + API for: - Colony command screen (timers, resources, queues) - Fleet launch, ETA calculation, recall logic - Active missions list - Basic automated tests validating core formulas - Budget & engagement Open to hourly or milestone based pricing - Looking for quality over speed - Long term work possible if this goes well When applying, briefly describe: - A system you’ve built where correctness mattered more than UX - How you avoid logic drift over time

Prompt Engineer – AI Systems & Automation Specialist

I'm looking for someone who can build a solid and reliable prompting framework that delivers measurable ROI for business use cases, not just impressive demos. We need a prompt engineer who thinks like a systems architect, not just someone who can write clever prompts. You'll be designing, testing, and optimizing prompts for production-grade AI workflows. This isn't about getting ChatGPT to write poems; it's about building reliable, scalable prompt chains that solve real business problems. Deliverables What You'll Do: Design and optimize prompts for LLM-powered automation workflows (GPT-4, Claude, open-source models) Build evaluation frameworks to measure prompt performance against business KPIs Develop prompt templates and chains for multi-step reasoning tasks Document prompt engineering patterns and create reusable libraries Collaborate on agentic AI systems using frameworks like LangChain Debug and iterate on prompts when model outputs don't meet specifications Required Skills & Experience: 2+ years hands-on prompt engineering experience (personal projects count if well-documented) Deep understanding of prompt patterns: chain-of-thought, few-shot learning, system prompt architecture, retrieval-augmented generation (RAG) Experience with prompt evaluation and A/B testing methodologies Familiarity with tokenization, context window management, and model-specific quirks Strong technical writing—you can explain complex prompt logic clearly Python proficiency for prompt testing and automation integration Preferred (Not Required): Background in ML/AI fundamentals (understanding of transformers, embeddings, fine-tuning concepts), at least foundational AI/ML understanding, you don't need to train models, but you understand concepts like temperature, context windows, and model limitations. Experience with n8n, Make, or similar automation platforms Exposure to agentic frameworks (LangChain, AutoGPT patterns, function calling) In your application, please begin your cover letter with the word "CONTEXT:" followed by a one-sentence summary of what makes our AI engineering approach different based on this job description. Applications without this will not be reviewed. Assessment Task (Required with Application) Instead of multiple interview rounds, complete this practical assessment: Scenario: A client wants to automate customer support ticket classification. Tickets should be categorized into: Billing, Technical, Feature Request, or Escalation. The model sometimes misclassifies urgent technical issues as "Feature Request." Your task: Write the system prompt you would use Provide 3-5 few-shot examples you'd include Explain your reasoning for structural choices Describe how you would evaluate and iterate on this prompt Time estimate: 30-45 minutes. We value thoughtful reasoning over speed. This task reveals: Do they understand edge cases? Can they structure prompts systematically? Do they think about evaluation? AI-generated responses typically miss the nuanced "why" behind choices. What Success Looks Like Prompts that work reliably at scale, not just in demos Clear documentation that another engineer could pick up Data-driven iteration, not just "try things until it works." To Apply: Submit your assessment response and a brief note on a prompt engineering challenge you've solved. Generic applications will not be reviewed.
