Senior Software Engineer (backend)

Accountabilities:

• • Influence the technical direction and architecture of critical backend systems responsible for job processing, workflow execution, and code execution.
  • Design, build, test, and maintain robust, highly available systems capable of supporting substantial data throughput and growing customer workloads.
  • Improve the performance and scalability of job and action processing systems to meet increasing demand and reliability requirements.
  • Develop internal and customer-facing controls for job prioritization, execution management, and workload balancing across multi-tenant environments.
  • Build and enhance capabilities that allow customers to safely execute code within the platform.
  • Investigate complex infrastructure, runtime, storage, and system-level issues using logs, traces, metrics, tests, and focused reproductions to identify root causes.
  • Write and review high-quality, maintainable, well-tested code while contributing improvements to engineering standards and developer productivity.
  • Take ownership of technical problems and solutions throughout their lifecycle, from implementation through production monitoring, customer feedback, and continuous improvement.
  • Identify opportunities to improve both the codebase and engineering processes, and actively contribute to making the broader team more effective.
  • Collaborate across the technology stack when needed, contributing to infrastructure, backend, and frontend initiatives beyond the primary area of responsibility.
  • Explore and refine the use of AI and LLM-based tools to improve engineering productivity, development workflows, and software delivery.
  • Share technical knowledge and learnings with colleagues and the wider engineering community through documentation, collaboration, and technical content.

  Requirements:

  • 6+ years of professional software engineering experience with a demonstrated track record of building and maintaining production-quality software.
  • Strong backend engineering fundamentals and an interest in working on high-throughput, highly available, and distributed systems.
  • Experience or strong interest in areas such as Linux systems, namespaces, file descriptors, Unix sockets, mounts, networking, and process isolation.
  • Experience with container runtimes, orchestration systems, code execution platforms, or similar infrastructure technologies is valuable.
  • Knowledge of filesystems and storage technologies, including POSIX behavior, content-addressed storage, or crash recovery, is a plus.
  • Experience working with low-level system primitives using languages such as Rust or Go is advantageous.
  • Strong debugging and problem-solving abilities, including the ability to isolate complex issues through logs, traces, metrics, testing, and targeted reproductions.
  • Comfortable working across a broad technical environment rather than being limited to a single specialized area.
  • Willingness to work with technologies such as Ruby, Rails, React, TypeScript, Rust, Go, PostgreSQL, Redis, AWS CDK, and Docker, with the understanding that expertise in every technology is not required.
  • Strong sense of ownership, accountability, curiosity, and willingness to contribute wherever the team needs support.
  • Ability to prioritize meaningful business and technical problems rather than pursuing complexity for its own sake.
  • Interest in developer experience, engineering efficiency, build performance, testing quality, and effective use of modern development tools including LLMs.
  • Strong communication and collaboration skills, with a respectful and supportive approach to working with colleagues.
  • Ability to work effectively in a sustainable environment that values reasonable working hours, realistic planning, continuous learning, and long-term performance.
  • No specific educational background is required; demonstrated technical capability, foundational knowledge, and professional experience are the primary considerations.
  • Candidates should be based in the Eastern Time Zone, with a preference for proximity to the Greater Boston area.

  Benefits:

  • Target salary range of $210,000–$220,000, plus equity.
  • Fully remote work within the United States.
  • Opportunity to work on highly visible backend systems with significant technical impact.
  • Broad technical exposure across backend engineering, infrastructure, execution systems, and developer experience.
  • Supportive and collaborative engineering environment with strong opportunities for learning and professional growth.
  • Emphasis on sustainable workloads, reasonable working hours, and taking holidays without a culture of overwork.
  • Strong focus on developer productivity, engineering quality, and effective use of modern AI-assisted development tools.
  • Inclusive workplace that values diverse perspectives, respectful collaboration, curiosity, and continuous improvement.
