About Openmesh and Xnode
Today, a few major corporations control most of the world's data and IT infrastructure, creating information asymmetry and a lack of trust. This is detrimental to businesses and society as a whole, leading to social inequality, scandals, and corruption. Openmesh aims to address this issue by providing an open-source cloud infrastructure and a global open data network. We aim to store important global data without intermediaries and act as a decentralized hub for the crypto and web3 ecosystem. Our goal is to expand our data coverage to include public health and scientific research data by 2023 and 2024.
Openmesh allows users to create their own decentralized data cloud, connecting globally, securely sharing data, and reducing deployment costs. Our network is designed to collect, store, process, stream, and provide data connectivity without requiring registration, licensing, or payments. Think of Openmesh as the internet's open data fabric, providing universal access and preventing interference from regulators, governments, corporations, and even its creators.
Core Products
Our flagship product, Xnode, is an essential part of Openmesh. Xnode is a revolutionary platform that enables developers to build decentralized data clouds quickly and easily. It provides data connectivity, data APIs, and query & analytics engines. With Xnode, developers can save time by creating data clouds within minutes rather than weeks or months. They only need to pay for computing and storage, avoiding licensing and setup fees. Xnode can reduce the operating costs of data clouds by 10-15 times and significantly improve deployment efficiency.
Pythia is our powerful analytics and query engine. It empowers users to transform raw data into actionable insights and enables them to design, build, visualize, and deploy robust data products.
Unified APIs provide a single endpoint for all crypto and web3 data, making it accessible to anyone without any costs or fees.
Our Vision
At Openmesh, our vision is to democratize data and address information asymmetry on a grand scale. We believe that access to reliable and unedited information is a fundamental right in a free and democratic society. To realize this vision, Openmesh has been designed to have no single authority that can manipulate data distribution or control who can access it. Our infrastructure and technology stack are open-source and governed by an open-source community.
About the Role
As the Senior Technical Product Manager of Unified APIs, you will play a vital role in shaping the future of decentralized data infrastructure. Your responsibility will include leading and guiding the improvement, scaling, and innovation of Unified APIs. Through this product, developers, businesses, data scientists, and financial forensic officers will have a single endpoint for all their web3 data. You will also contribute to expanding our data coverage to new areas, including public health and scientific research.

Hey everyone,
I’m looking for recommendations or to connect directly with a marketing team / agency that genuinely understands the Forex trading space — especially community-led growth.
I run many public XAUUSD signals Telegram channel that has grown organically to 12,000+ members over the years (since 2020). No ads, no clickbait, no fake screenshots. The channel is completely free and will stay that way because the core idea has always been transparency and live testing rather than selling promises.
A few things about the community:
• Signals focused only on FX & XAUUSD
• Consistent average accuracy around ~78%
• Clear risk management & lot sizing shared with every setup
• Priority is always capital protection, not overtrading
• Everything is public so anyone can track performance in real time for as long as they want
The growth so far has been word-of-mouth and organic, but now I want to scale this community responsibly and reach 100,000+ free members this year without turning it into a hype machine.
I’m not looking for generic social media marketers. I’m specifically interested in people/agencies who:
• Understand traders, not just traffic
• Can grow communities ethically and sustainably
• Know how to position transparency as a strength (not fake luxury marketing)
• Have experience with Telegram / Instagram / Reddit / Trading communities
If you’re a marketer in this niche, or you’ve worked with someone solid before, I’d really appreciate guidance, referrals, or a conversation.
Thanks in advance 🙏
Happy to share more details in DMs.

Senior Rust Developer

About the Role
We're looking for a Senior Rust Developer to join our core engineering team and own the systems that sit closest to the market. This means low-latency order execution engines, high-throughput market data pipelines, real-time streaming infrastructure, and integrations with both centralized and decentralized exchanges. Every millisecond and every line of code matters here, and you'll be the person making sure it all holds up under pressure. This is not a role for someone who wants to write Rust adjacent to trading. You'll be building the backbone of live production systems where correctness, safety, and raw performance have direct P&L consequences. You'll work alongside quantitative researchers and other engineers to implement and deploy strategies, and you'll have meaningful input into the infrastructure decisions that shape how we build and scale. If you've spent years pushing Rust to its limits in high-performance environments and you want that work to matter in real markets in real time, this is the role.
Responsibilities
Design, build, and maintain high-throughput, low-latency trading systems in Rust
Develop and optimize order execution engines, market data feeds, and real-time processing pipelines
Build reliable integrations with centralized and decentralized exchanges across CEX and DEX environments
Architect systems for real-time streaming data and WebSocket communication at scale
Write safe, well-tested concurrent code leveraging async runtimes including Tokio and async-std
Collaborate with quantitative researchers to implement and deploy trading strategies into production
Profile, benchmark, and eliminate performance bottlenecks across critical system paths
Contribute to infrastructure decisions around deployment, observability, and fault tolerance
Requirements
5+ years of professional software engineering experience
2+ years building and maintaining production systems in Rust, and you will be tested on it
Deep command of Rust's ownership model, lifetimes, traits, and async patterns
Experience with high-performance networking including TCP/UDP, WebSockets, and gRPC
Strong understanding of concurrency primitives and lock-free data structures
Familiarity with financial systems, trading platforms, or real-time data pipelines
Linux systems programming and performance tuning experience
Comfortable working independently in a fast-paced, remote-first environment
Nice to Have
Experience with cryptocurrency exchanges, DeFi protocols, or blockchain RPC nodes
Knowledge of FIX protocol or other financial messaging standards
Open-source Rust contributions
Experience with FPGA or kernel-bypass networking such as DPDK or io_uring
Familiarity with quantitative trading concepts including order books and market microstructure
Infrastructure experience with Docker, Kubernetes, Terraform, or Prometheus/Grafana
