Why This Job is Featured on The SaaS Jobs
Backend engineering roles in SaaS become most consequential when they sit at the intersection of product evolution and operational scale, and this one is framed around building the backend systems that power products from prototype through large deployments. The remit spans services, APIs, data models, and infrastructure, with an emphasis on security and performance, signalling a platform-minded role rather than a narrow feature lane. The stated collaboration with product, hardware, and full-stack teams also points to a SaaS environment where backend decisions are closely tied to end-to-end user experience and delivery constraints.
For a long-term SaaS career, the value here is repeated exposure to the classic problems that compound over time: designing interfaces that can survive changing requirements, managing tradeoffs between iteration speed and maintainability, and building systems that remain reliable as usage grows. Work that blends architecture with day-to-day delivery tends to develop strong judgment around observability, scalability, and operational readiness, all of which transfer across SaaS domains.
This role fits engineers who prefer owning foundational components and making technical decisions with broad product impact. It is also well suited to professionals who enjoy cross-functional problem solving and keeping enough context across the stack to choose pragmatic designs, particularly in environments where backend systems must support multiple client surfaces and deployment stages.
The section above is editorial commentary from The SaaS Jobs, provided to help SaaS professionals understand the role in a broader industry context.
Job Description
About the Team
The Software Engineering team is responsible for designing and building the scalable, performant, and secure backend systems that power our products—from early prototypes to large-scale deployments. We collaborate closely with product, hardware, and full-stack teams to ensure our infrastructure enables fast iteration while setting a strong foundation for long-term growth.
About the Role
As a Backend Engineer, you will design and build services, APIs, and infrastructure that support evolving product needs. You’ll apply a deep understanding of backend systems and maintain enough end-to-end context—from hardware to cloud—to guide technical decisions that best serve the product and team.
We’re looking for engineers who thrive in fast-paced, collaborative environments and care deeply about building robust systems that scale.
This role is based in San Francisco, CA. We use a hybrid work model of four days in the office per week and offer relocation assistance to new employees.
In this role, you will:
Architect, build, and maintain high-performance, secure backend systems.
Design APIs, data models, and infrastructure to support evolving product needs.
Balance near-term development velocity with long-term maintainability and scalability.
Collaborate with cross-functional teams to ensure cohesive, end-to-end solutions.
You might thrive in this role if you:
Have 7+ years of professional software engineering experience, with a focus on backend systems.
Have a proven track record of building and scaling systems from early stage to large scale.
Are proficient with Python and Go, and familiar with a range of server-side technologies.
Have a strong grasp of system design, performance optimization, and security best practices.
Can reason about full-stack tradeoffs from hardware through cloud infrastructure.
(Nice to have) Have experience with distributed systems and cloud architectures.
(Nice to have) Bring a background in instrumentation, analytics, and performance tuning.
(Nice to have) Are familiar with hardware-cloud integrations or applied AI services.
