Senior Software Engineer - Rust - Consumer

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Senior Software Engineer – Rust – Consumer based in Brazil. Join a globally distributed engineering team building intuitive, high-performance financial products designed to make cryptocurrency accessible to millions of people worldwide. As a Senior Software Engineer, you will shape the technical direction of customer-facing applications and build robust backend services that power trading, payments, and crypto experiences. You will take ownership of complex engineering challenges, from architectural design and implementation to product launches and measurable customer outcomes. Working closely with product leaders and cross-functional engineering teams, you will influence roadmaps, drive technical decisions, and deliver solutions that scale. You will also mentor fellow engineers, establish best practices, and help raise the bar for engineering quality across the organization. The team embraces an AI-first development approach, encouraging engineers to leverage intelligent tools to accelerate delivery and expand their technical capabilities. This is an opportunity to combine deep Rust expertise, product thinking, and end-to-end ownership to shape the future of consumer-facing digital finance. Accountabilities - Lead technical architecture and delivery: Own the design, development, and delivery of customer-facing Rust backend services supporting trading, payments, and cryptocurrency experiences, making architectural decisions that prioritize scalability, reliability, and long-term maintainability. - Drive complex engineering initiatives: Take ambiguous, multi-quarter projects from initial discovery through implementation, launch, and measurement, breaking down complex challenges into manageable workstreams that enable parallel execution.

- Own end-to-end product outcomes: Go beyond backend implementation to understand the broader customer experience, collaborate across frontend and backend systems, and ensure technical solutions address real user needs. - Shape product strategy and roadmaps: Partner with product leadership to define priorities, influence feature decisions, evaluate trade-offs, and take accountability for the outcomes and performance metrics of delivered solutions. - Coordinate cross-functional initiatives: Work closely with trading infrastructure, platform engineering, and other product teams to establish technical alignment, manage dependencies, and deliver initiatives that span multiple teams. - Mentor and develop engineers: Support the growth of mid-level engineers through mentorship, thoughtful code and design reviews, technical documentation, and the development of shared engineering standards. - Champion AI-assisted engineering: Integrate AI tools into daily development workflows to accelerate coding, explore unfamiliar codebases, validate implementations, and solve problems across technical domains. Help establish effective practices for AI-assisted software development across the team. - Promote engineering excellence: Maintain high standards for code quality, system design, technical decision-making, and customer experience while balancing rapid delivery with reliability and long-term product quality. Requirements - Professional experience: At least 6 years of backend software engineering experience, with substantial hands-on expertise in Rust. - Rust and distributed systems: Strong knowledge of asynchronous programming, network services, distributed systems, RPC protocols, Kafka, and event-driven architectures. - Architecture and technical ownership: Proven experience designing and operating production systems, making architectural decisions, understanding their long-term consequences, and evaluating technical trade-offs.
