Senior Rust Engineer / Middleware Architect

Senior Rust Engineer / Middleware Architect

Remote | B2B Contract | Full-time

Who Are We?

We’re a fast-moving product team embedded in a major public company with over 40 real-world legal and property services across multiple countries. From real estate deals and corporate registry checks to KYC and lien verification our solutions touch millions of lives and billions in assets.

We’re now building something new : a unified platform to replace decades of siloed tech. Backed by the leadership and resources of a large-scale company, we operate like a startup inside an enterprise with startup speed, ownership, and product focus.

What Do We Do?

Our mission is to build the next-generation legaltech / proptech platform modern, scalable, and built around real user needs. We’re moving away from legacy regional stacks and designing a global backend infrastructure that’s modular, efficient, and future-proof.

At the heart of this transformation is the middleware routing service that will power secure, high-performance data flows across the entire system.

Why Do We Do It?

Because access to legal and property services shouldn’t depend on bureaucracy, outdated systems, or regional constraints. We want to standardize trust across borders making it as easy to verify a corporate registry in Poland as it is to confirm a lien in Spain.

This platform is the infrastructure for that vision.

How Do We Work?

We combine the agility of a small product team with the scale and stability of a major enterprise.

Product-driven : No feature bloat. Everything we build serves real users.

Remote-first : Work where you're best we optimize for results, not office hours.

Engineer-led : Architecture decisions come from those who build, not from layers of management.

AI-augmented : We actively integrate LLMs and AI-powered tooling into our dev workflows.

Who’s on the Team?

We’re led by a hands-on architect who’s previously scaled fintech and legaltech systems, and who’s not afraid to jump into the codebase. Our growing team includes frontend and backend engineers, designers, and product managers many with experience in AI, data platforms, and public services.

We’re pragmatic, collaborative, and allergic to fluff.

Why Is There a Vacancy?

Because this service is mission-critical and we need a specialist who can build it right.

Who Are We Looking For?

You’re an experienced Rust developer or systems architect who :

Builds reliable, fast, and secure services.

Thrives in an ownership-heavy environment.

Can make tough architectural calls, communicate clearly, and execute independently.

Isn’t scared of low-level systems or abstract concepts.

Has worked on or is eager to work on multi-tenant infrastructure, SQL routing, and performance-critical services.

What Professional Skills Matter?

• 4+ years in systems / backend engineering, 2+ years in Rust.
• Experience building microservices and / or middleware layers.
• Strong understanding of auth-based routing, secure system design, and multi-tenant architectures.
