About the Role:
An impressive mission requires an equally impressive Senior Software Engineer.
As a key technical contributor at VIA, you will be instrumental in architecting and constructing the pioneering, secure, and scalable software that underpins VIA's mission. You will directly influence how critical data is protected and shared, leveraging our advanced Web3, quantum-resistant technologies.
This role offers a chance to significantly contribute by creating high-quality, secure software and tackling intricate data problems for individuals who are driven by innovation and dedicated to excellence.
In this role, you will:
  • Architect and implement secure, reliable, and scalable microservices, applying deep understanding of software architecture principles and best practices.
  • Integrate VIA's Web3 components and privacy-preserving technologies to deliver cutting-edge features and innovative platform functionality.
  • Define, document, and drive adoption of end-to-end software development lifecycle (SDLC) processes, ensuring clarity and efficiency from initial concept through deployment and maintenance.
  • Spearhead the creation, development, and optimization of automation pipelines for continuous integration, testing, and deployment (CI/CD), ensuring efficient and reliable application releases.
  • Develop and execute comprehensive automated testing strategies, including unit and integration tests, to deliver high-quality, robust software.
  • Proactively monitor, troubleshoot, analyze, and optimize the performance of deployed applications, working to mitigate bottlenecks.
  • Serve as a subject matter expert and provide technical leadership in privacy and security, guiding project delivery and ensuring VIA's solutions meet the highest standards.
  • Clearly articulate complex software designs, architectural choices, and technical processes to diverse audiences, including technical peers and non-technical stakeholders.
  • Collaborate effectively with various cross-functional teams to ensure alignment, solve problems, and achieve successful project outcomes.
  • Rapidly grasp new technical concepts and effectively apply this knowledge to address complex challenges and develop innovative solutions that meet customer needs.
  • Continuously explore and thoughtfully integrate relevant advancements in privacy, cryptography, and distributed systems to contribute to VIA's cutting-edge products.
What you will bring to this role:
  • Bachelor's degree or higher in computer science, mathematics, engineering, or science
  • 5+ years of relevant full stack or backend development experience
  • Strong experience with cloud-based software development in a microservices environment and cryptography techniques, including:
  • Developing RESTful APIs (using frameworks such as FastAPI) secured by OAuth2/Auth
  • Integrating asymmetric and/or symmetric encryption in applications
  • Thorough working knowledge of data structures, algorithms, databases (SQL and NoSQL), and in-memory data storage
  • Extensive knowledge of parallel processing, message brokers, and/or distributed task queues
  • Working knowledge of Docker containers
  • Previous experience leading an Agile team of developers a plus:
  • Proven on-time delivery of multiple quality software projects
  • Ability to advocate for technical excellence, maintaining the highest standard of software engineering practices
  • Model an ability to identify blockers and use critical thinking to provide creative solutions
  • Proficiency in documentation and the desire to clearly communicate technical processes to both non-technical and technical audiences.
  • Exposure to the following a plus: IETF RFCs, blockchain systems, zero-knowledge proofs
  • Service mesh (Istio), zero trust architecture and observability
  • Working knowledge of Helm charts
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
