Workload — Full-time
Duration — 3months+

We are looking for a Mobile Software Engineer to help build and evolve a decentralized mobile wallet powered by a deterministic Rust SDK. This role focuses primarily on Swift development while requiring strong systems thinking and comfort working across Swift Rust FFI boundaries. The tech stack that you will interact with will be Swift, Rust, Kotlin, Rust FFI, and Objective C, mostly in that order. You will be working with engineers and developers on the mobile team within our org. This is an opportunity to work remotely in a team that uses modern coding practices and operates without a centralized backend, prioritizing client-side verification and security. Responsibilities Collaborate with engineers to design, implement, and ship new wallet features.Implement wallet features on top of a deterministic SDK, ensuring correctness and security across the full stack.Improve our mobile SDKs. This may involve improvements to the foundational Rust SDK.We use AI-assisted development tools. Engineers are expected to critically evaluate and validate all generated code.Improve our continuous integration.Requirements Either: 3+ years professional software engineering experience, with significant experience in Swift (production iOS apps). Exceptional recent graduates with demonstrable systems, distributed systems, compiler, or cryptography experience.Strong understanding of deterministic state machines and ability to reason about correctness in financial or security-sensitive systems.Comfortable working across language boundaries (Swift Rust FFI), including understanding of memory ownership, threading, and error propagation.Conceptual understanding of cryptographic primitives (hashes, signatures, key derivation, Merkle trees).Experience building mobile applications that rely on complex local business logic or SDKs.Strong debugging skills across stack boundaries (mobile SDK networking).Proficient with Git and modern collaborative workflows.Strong Linux/macOS command-line skills.Ability to work remotely in a self-directed environment.Strong written and spoken English.This is not a typical UI-focused mobile role. Candidates should be comfortable reasoning about state, correctness, and security in adversarial environments.Nice to Have Working knowledge of Rust.Experience working with Rust FFI or other foreign-function interfaces.Experience with Android development.Understanding of UTXO vs account-based blockchain models.Familiarity with SPV or client-side transaction verification.Experience with cryptographic or privacy-preserving systems.Background in distributed systems.Comfort verifying and correcting AI-generated code in security-sensitive environments.

📝 Note:
What you'll do: Compatibility Testing: Conduct compatibility testing to ensure seamless interoperability between various IoT devices, sensors, gateways, protocols, and platforms. Functional Testing: Verify the functional correctness of IoT applications by testing features such as data collection, storage, processing, real-time monitoring, control, and integration with other systems. Performance Testing: Evaluate the performance of IoT systems under different workloads, network conditions, and environmental factors to identify bottlenecks, latency issues, and scalability limitations. Security Testing: Conduct thorough security assessments to identify and mitigate vulnerabilities in IoT devices, communication protocols, data transmission, storage, access controls, and authentication mechanisms. Estimate your work. Mentor less experienced team members to help them succeed and grow. Participate in the requirement discussion meetings and daily calls, and provide feedback on inconsistencies and open issues. Take part in knowledge sharing with other tech freaks. What we expect: At least 4 years of professional experience as a mobile tester. Experience with test case management tools (e.g. TestRail, Qase) and Atlassian tools. Solid knowledge in the field of software quality assurance. At least B2 English skills (both written and spoken). Out-of-the-box thinking and creativity (we care about your problem-solving skills). Precision, curiosity, perceptiveness, patience. Self-reliance, responsibility for assigned tasks, and effective time management. Keeping track of the industry trends and taking the initiative to incorporate these into the company technologies. Engagement and team-play. It’d be nice if you have: Experience in projects involving physical devices (e.g. wearables). Knowledge of the creation and maintenance of automated tests. Practice in API testing (Postman preferred) and database testing. Experience with web app testing and web-debugging proxy tools (e.g. Charles, Proxyman). ISTQB Foundation (or higher) certificate. Experience in working in Agile or Scrum environments.
