Full-stack Engineer (Rust/System Performance)
Full-stack Engineer (Rust / System Performance)
We’re pushing computers beyond their limits
We’re building a platform that removes OS-level bloat and pushes Windows devices beyond their factory performance, extending lifespan, unlocking speed, and reducing global e-waste.
This isn’t another SaaS dashboard- This is system-level performance engineering — close to the OS, where small changes create massive impact.
Backed by 2.6M+ users through AtlasOS and 5,000+ daily downloads, we’re now turning this into a scalable SaaS platform across consumer and enterprise markets.
We have distribution.
We have demand.
Now we’re building the product that scales it.
About eclean
eclean is a B2C & B2B IT optimization SaaS built to extend device lifespan and eliminate performance loss. Created by the team behind AtlasOS, we’re solving a real problem at global scale; slow devices, unnecessary hardware upgrades, and growing e-waste.
By pushing devices to perform better than when they were new, we help consumers, gamers, and enterprises save money while reducing environmental impact.
The role
We’re looking for a Full-stack Engineer who wants to build something technically challenging and meaningful. You’ll work across Rust, Tauri, Svelte, and Go — shaping both the product and how performance is delivered at scale.
You’ll have real ownership:
Build features end-to-end
Solve hard technical problems
Make decisions that directly impact millions of users
What you’ll work on
Build and evolve our desktop application using Rust + Tauri
Develop high-performance UI with Svelte
Work across the stack with our Go backend
Identify and eliminate performance bottlenecks at system level
Improve how software interacts with Windows internals
Ship fast, iterate, and continuously improve real user experience
Tech stack; Rust · Tauri · Svelte · Go · Windows internals
Who this is for
Enjoys working close to the OS layer
Likes solving performance problems, not just building CRUD apps
Prefers ownership over process
Comfortable figuring things out independently
This role is not for
Those who want clearly defined tasks and slow-moving environments
Those who prefer abstraction over understanding system behavior
Requirements
Strong experience with Rust and modern software development
Experience with Svelte / Go / Tauri is a strong plus
Excellent problem-solving and debugging skills
Fluent in English
Nice to have:
Experience with Windows APIs / system-level development
Swedish
Why join now
Proven distribution (millions of users)
Early-stage product with real traction
High-impact technical challenges
Opportunity to shape architecture and product early
This is a rare moment, before scale is fully unlocked, but after product-market demand is proven.
Engagement
6-month contractor role with strong potential to convert to full-time
Fully remote (Sweden preferred but can consider EU based)
You are comfortable working as an independent contractor
