What is a senior backend software engineer?

Senior Backend Software Engineers are experienced professionals responsible for designing, developing, and maintaining the server-side logic, databases, and APIs that power web and software applications. They work closely with front-end developers, product managers, and other team members to ensure robust, scalable, and secure systems. In addition to coding, they often mentor junior engineers, conduct code reviews, and help shape the architecture and technical direction of projects. Their expertise enables businesses to handle high volumes of data, users, and complex business logic efficiently.

How does a senior backend software engineer typically collaborate with frontend teams and other stakeholders during the development process?

Senior Backend Software Engineers frequently work closely with frontend developers, product managers, and sometimes UX designers to ensure seamless integration between server-side logic and user-facing features. This collaboration often involves participating in planning meetings, discussing API contracts, and reviewing architectural decisions to ensure scalability and performance. Clear communication and regular sync-ups are essential, as backend engineers need to translate business requirements into robust technical solutions while addressing any integration challenges that arise.

What are the key skills and qualifications needed to thrive as a senior backend software engineer, and why are they important?

To thrive as a Senior Backend Software Engineer, you need advanced programming skills (such as Python, Java, or Go), a deep understanding of system architecture, and a relevant degree or equivalent experience. Familiarity with databases, cloud platforms (like AWS or Azure), containerization tools (Docker, Kubernetes), and CI/CD pipelines is typically required, along with knowledge of best practices in API design and security. Exceptional problem-solving abilities, strong communication, and leadership skills help you effectively collaborate and mentor junior engineers. These competencies are crucial for building robust, scalable systems and ensuring the technical success of complex projects.

The main difference between a Senior Backend Software Engineer and a Backend Developer lies in experience, responsibilities, and scope. Senior engineers handle complex systems, mentor teams, and contribute to architecture, while backend developers focus on coding and maintaining backend features. Both roles require strong technical skills, but senior roles demand more leadership and strategic input.

Job description

As a Senior Backend Software Engineer on our Diagnostics team, you'll build the part of Regard that reads a patient's medical chart — labs, medications, vitals, procedures, prior notes, history — and determines which conditions are present, along with the evidence supporting each one. You'll design and develop critical backend services and drive them end-to-end through the full product lifecycle: ideation, planning, design, execution, deployment, and iteration.

Our senior engineers are true technical leaders by driving architectural decisions, mentoring teammates, and leading major projects that help set the bar for engineering excellence. You'll collaborate closely with product, design, clinicians, and fellow engineers to ship high-quality solutions that empower physicians and improve patient care.

 

About Regard

Our mission is to bring world-class healthcare to everyone. Regard is an AI-powered Proactive Documentation platform that advances how care is delivered by reviewing all patient data in the EHR to recommend diagnoses and surface clinical evidence. Regard drafts a note even before the physician sees the patient, enabling an approach that gets documentation right at the point of care - we call it Proactive Documentation. This improves quality of care, reduces physician burden, and improves hospital finances. We are excited by challenges, mission-oriented work, and meaningful relationships. We work closely with some of the top health systems in the country and are leading the change that healthcare - one of the largest and most inefficient industries in the world - needs. We want you to join us.

 

Our Tech Stack:

  • Backend: Python, Go, PostgreSQL, Redis, Celery

  • Frontend: TypeScript, React

  • Infrastructure & DevOps: AWS, Docker, Kubernetes, GitLab CI/CD, Datadog

  • AI: OpenAI, Anthropic

  • Clinical standards: FHIR, ICD-10, SNOMED, LOINC, RxNorm

 

Responsibilities:

  • Collaborate with product, design, and clinicians to design medium-to-large projects, often starting from an ambiguous problem statement and balancing speed to market, user experience, business goals, and technical architecture quality

  • Own backend services and drive improvements across system design, observability, testing, performance, and support

  • Model clinical data and design the schemas and service contracts that new product surfaces are built on

  • Work directly with clinicians to understand what a diagnosis requires, and turn that intent into logic and tooling they can extend themselves

  • Mentor and review code from other developers across backend services

  • Maintain and improve the quality of the codebase and tooling in your area of responsibility through proactive fixes and by proposing projects that improve the overall backend codebase

  • Participate in operational activities including on-call, monitoring, and production support

 

Minimum Qualifications:

  • BS in Computer Science or equivalent experience

  • 6+ years of professional experience with software development

  • Proficient in Python or Go with demonstrated ability to write and maintain production-quality code

  • Proven experience building data-intensive applications, backed by strong data fluency in designing and evolving schemas consumed across cross-functional teams

  • Able to participate in on-call operational support for your areas of responsibility

  • Able to travel up to 4 weeks a year for company co-working and/or retreat weeks

  • Practical experience leveraging AI coding tools in day-to-day software development (e.g., Cursor, Claude Code, Codex)

 

Preferred Qualifications:

  • Exposure to clinical or healthcare data (e.g., FHIR, EMR integrations, clinical terminologies, or revenue cycle)

  • Comfortable with systems that produce ranked, scored, or probabilistic output and evaluating that output against imperfect ground truth

  • Experience in a startup and/or high-growth environments

  • Experience building tools for non-engineer domain experts

  • Experience managing cloud infrastructure and LLM integrations

  • Experience working on a mature enterprise SaaS product

  • For this role, Regard is currently only considering candidates who are authorized to work in the US without visa sponsorship, and are within the New York City metro area, San Francisco Bay Area, or Los Angeles

  • Our expectation for this role is to be in the office 2 days per week. We also require more frequent in-office work during the onboarding period and team onsite weeks up to once per month.

  • We will provide relocation assistance to anyone who does not already reside in the NYC metro area

  • For those who enjoy working from the office on a more regular basis, we offer catered lunches and other fun perks

  • Additionally, hybrid employees have the flexibility to work from locations outside of their home office from up to 6 weeks per year

  • 99% employer paid health benefits (Medical, Dental, and Vision) + One Medical subscription

  • 18 PTO days/yr + 1 week holiday break

  • Monthly health & wellness budget
