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

Instead, you will: - Review backend pull requests for correctness and spec compliance - Enforce deterministic behaviour and rule consistency - Ensure APIs match frontend expectations - Flag logic drift, hidden assumptions, and edge case bugs - Help define and review automated test coverage - Advise on architecture, data integrity, and deployment basics - Think: guard rails, not velocity. Why this role exists This project has: - A strict ruleset - No RNG - No catch up mechanics - No “we’ll fix it later” tolerance I want a second set of experienced eyes to prevent: - Silent logic errors - “Helpful” but incorrect changes - Technical debt that only shows up months later Ideal background You’re a good fit if you have experience with: - Backend systems with complex rules - Game logic, simulations, or financial/ledger style systems - Code review and architectural oversight - Saying “this is wrong” clearly and early You do not need game industry experience, correctness matters more than genre.

Structural Engineer to review as-built dormer roof + foundations

I need a UK-based structural engineer confirm the structural design for my house project and produce a Building Control–ready pack. Part of the loft conversion (including a pitched dormer) has already been built and Building Control have said there are things missing from the previous engineer’s calculations because they do not show how the dormer integrates into the roof or how the ridge is supported. I now need an engineer to review the as-built structure (photos available) and issue revised calculations and drawings that building control can approve. I need someone who is able to put together the information required by building control. I attach the previous document but this is the reply I got from building control: I also need some calculations to confirm that the 2 story (1.5 story really...) extension built from 200mm structural insulated panels (SIPs) are suitable at 1m depth in clay soil. Good morning and thank you for sending through the structural calculations. Having had a quick look through that information, it appears there maybe some information missing in that document, as there is no reference to the pitched loft dormer section of the roof to the loft conversion and how that integrates with the main roof? We would normally expect the engineer to produce a drawing that shows all the roof timbers and structural supporting beams for a loft conversion. At present the only drawing section in the calculations document appears to show only the main roof section, with no reference to the additional load that will come from the pitched timber dormer section, that will need to connect into the main roof/ridge timber. The dormer side wall/timbers also need to be supported and generally those would need to be either double or triple timbers each side to support those side cheek walls. We would also query/question the fact that only a single ridge board is shown to the main roof. Generally, where a dormer roof is formed as part of a loft conversion, we would normally expect to see either a flitch beam or even a steel ridge beam used at that location where there may be additional loading paced on the ridge . This is something we feel the engineer would need to consider and provide calculations & additional drawing details for please as part of their design at this stage. If there are any other beams required as part of the extension works, then those should also be included within the structural calculations please. Please discuss this further with your engineer and re-submit any additional information when completed for the loft conversion.
