About Foundation X (FXT)

FXT is a next-generation SaaS platform built for gaming and entertainment brands, making it simple for developers to transition from Web2 into Web3. With AI driven plug-and-play APIs, SDKs, and a robust live services backend, FXT helps studios cut complexity, accelerate time to market, and unlock new revenue streams through seamless Web2 + Web3 integration.

We are on a mission to simplify Web3 for game developers and create an economy that benefits developers and players within the FXT platform ecosystem.

 

The Role

We’re looking for a Software Engineer who thrives at the intersection of technical design and strategic planning, someone who can help define, shape, and execute the technical roadmap that will guide FXT’s evolution from MVP to scalable global platform.

You’ll work closely with the CEO and founding team to translate FXT’s vision into a clear, actionable, and technically sound roadmap. You’ll help define the system architecture, evaluate key technology decisions (AI integration, SDK modularity, API scalability, data pipelines, Web3 interoperability), and ensure engineering efforts align with product milestones and long-term goals.

This role is ideal for an engineer with strong architectural instincts who enjoys systems thinking, strategic problem-solving, and building from zero to one.

 

Responsibilities

Design and document the technical roadmap for FXT’s core platform, aligning with product and business priorities
Work with leadership to define milestones, MVP features, and scaling phases — from prototype to full production launch
Design system architecture for core components — APIs, SDKs, data flows, wallet systems, and AI integration layers
Evaluate technical trade-offs and make recommendations on stack choices, frameworks, and scalability solutions
Collaborate cross-functionally with product, data, and operations teams to ensure roadmap feasibility
Create and maintain documentation for internal teams and potential investors / grant submissions
Contribute to early codebase design, prototyping, and proof-of-concept builds.
Support technical recruitment and mentorship of future engineers as the team scales

 

Requirements

5+ years of software engineering experience with strong exposure to backend architecture and systems design
Proven experience in building developer platforms, SaaS products, or gaming infrastructure tools
Solid understanding of API design, microservices, and data architecture
Familiarity with Web3 technologies (smart contracts, custodial wallets, tokenisation) and AI integrations preferred
Proficiency in one or more of: TypeScript, Python, Go, or Node.js
Strong documentation, planning, and communication skills — ability to translate technical complexity into clear milestones
A builder’s mindset: resourceful, collaborative, and comfortable operating in an early-stage startup environment

 

Nice to Have

Experience with gaming SDKs, Unity/Unreal integrations, or cloud-based developer tools
Knowledge of AI/ML toolchains or API orchestration platforms.
Experience designing and validating early-stage architectures or proof-of-concept systems

 

What We Offer

Opportunity to shape a platform at the cutting edge of gaming & Web3
Opportunity to work on cross-disciplinary innovation — combining gaming, blockchain, and AI
Collaborative, ambitious, and forward-thinking team culture
Competitive salary
Flexible working environment (remote)
