Senior Software Engineer (backend)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer (backend) based in the United States.

This role offers the opportunity to work on highly critical backend systems that power intelligent, automated workflows at significant scale. You’ll focus primarily on improving the throughput, reliability, and performance of job processing and code execution systems. The position combines hands-on engineering with meaningful influence over technical direction, product evolution, and engineering practices. You’ll work in a collaborative, supportive environment where engineers are encouraged to take ownership from initial design through production and beyond. Although backend systems are the primary focus, the role offers broad exposure across infrastructure, developer experience, and other parts of the technology stack. You’ll tackle complex technical challenges involving distributed systems, containers, storage, execution environments, and high-volume workloads. This is an opportunity to make highly visible contributions while working sustainably with a team that values simplicity, speed, sound engineering, and continuous learning.

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.
