Senior Rust Developer (Secure Backend with Web Portal)/Fully remote

Excellent contract opportunity for a Rust Developer to design and implement a secure Back End with an integrated web portal. The ideal candidate will combine strong Back End expertise (APIs, databases, messaging) with Front End integration using HTMX and Tailwind CSS for dynamic, responsive, and modern user experiences.

You will play a key role in building a robust, scalable, and compliant system with strong security foundations. Experience with Dioxus is a plus, especially for cross-platform or desktop/web hybrid use cases.

Key Responsibilities

• Design and maintain secure Back End services and web portal using Rust.
• Develop and integrate REST APIs (design, documentation, versioning).
• Implement Server Side rendering (SSR) with Rust template engines (Askama, Tera).
• Build responsive, accessible UIs with HTMX + Tailwind CSS.
• Integrate PostgreSQL via SQLx (async, type-safe queries) and manage database migrations.
• Work with messaging systems (Kafka) for event-driven communication.
• Implement authentication and authorization (OAuth2, OIDC, JWT, RBAC/ABAC).
• Apply security best practices (OWASP Top 10, input validation, CSRF/XSS prevention, TLS/HTTPS).
• Ensure observability through logging, metrics, and tracing (eg, tracing, OpenTelemetry).
• Collaborate on architecture, scalability, and DevOps (containerization, CI/CD).

Required Qualifications

• Strong experience building production-grade applications in Rust.
• Proficiency with Rust async ecosystem (Tokio, async/await).
• Hands-on experience with REST API development and integration.
• Practical knowledge of PostgreSQL + SQLx.
• Experience with Kafka or equivalent messaging systems.
• Familiarity with HTMX and SSR (Askama, Tera, or similar).
• Experience with Tailwind CSS for modern, responsive UI design.
• Solid understanding of authentication/authorization standards (OAuth2, JWT).
• Applied knowledge of web security best practices (OWASP, TLS, CSRF, XSS, SQLi).
• Git-based workflows and collaborative development practices.
• Strong problem-solving and communication skills.

Preferred Qualifications (Nice-to-Have)

• Experience with Dioxus for cross-platform Rust UI development.
• Knowledge of containerization (Docker) and orchestration (Kubernetes).
• Familiarity with CI/CD pipelines (GitHub Actions, GitLab CI, or similar).
• Experience with monitoring/observability tools (Prometheus, Grafana, ELK/EFK stack).
• Knowledge of caching solutions (Redis, Memcached).
• Exposure to compliance frameworks (GDPR, ISO 27001, eIDAS, or similar).
• Interest in multi-language support and accessibility standards.
