Sr Software information

What does a senior software engineer do?

A Sr Software Engineer is responsible for designing, developing, and maintaining complex software applications. They often lead technical projects, mentor junior team members, and collaborate closely with stakeholders to ensure software meets business objectives. Their role typically involves writing high-quality code, reviewing code from peers, and making architectural decisions. Sr Software Engineers are also expected to stay updated with industry trends and best practices to improve software performance and reliability.

What are the key skills and qualifications needed to thrive as a senior software engineer?

To thrive as a Senior Software Engineer, you need strong proficiency in programming languages (such as Java, Python, or C#), software architecture, and a bachelor’s degree in computer science or a related field. Expertise with development frameworks, version control systems like Git, and cloud platforms such as AWS or Azure is commonly required, along with certifications like AWS Certified Solutions Architect. Leadership, problem-solving, and effective communication skills help you mentor junior engineers and collaborate across teams. These skills ensure the delivery of robust, scalable solutions and foster innovation within complex technical environments.

What are some common challenges faced by senior software engineers when leading project teams, and how can they effectively overcome them?

Senior Software Engineers often encounter challenges such as balancing hands-on coding with mentoring less experienced team members, managing project timelines, and ensuring code quality across the team. Effective communication and proactive planning are key to overcoming these hurdles. By fostering a collaborative environment, setting clear expectations, and leveraging agile methodologies, Senior Software Engineers can guide their teams to successful project delivery while supporting professional growth within the team.

Job description

Hi, we're Oscar. We're hiring a Senior Software Engineer, Backend to join our Engineering team.

Oscar is the first health insurance company built around a full stack technology platform and a focus on serving our members. We started Oscar in 2012 to create the kind of health insurance company we would want for ourselves—one that behaves like a doctor in the family.

About the role

As a Senior Software Engineer, you will build reliable and maintainable applications, infrastructure, and interfaces that make interacting with the health care system easier for members and providers. You will work with partners, product managers, and designers to solve challenging problems. Senior Engineers collaborate with other engineers on the team to improve technology and apply best practices.

Work Location:

Oscar is a blended work culture where everyone, regardless of work type or location, feels connected to their teammates, our culture and our mission.

This is a hybrid position, you will need to live within commutable distance to our New York City office (in Hudson Square), our Tempe office (off the 101 at University Dr), or our Los Angeles office (in Marina Del Rey), and will be expected to come into the office at least two days each week.

Pay Transparency:

The base pay for this role is: $158,400 - $207,900 per year. You are also eligible for employee benefits, participation in Oscar's unlimited vacation program, company equity grants, and annual performance bonuses.

Responsibilities
  • Become the expert on your team's business and technical domains.
  • Lead the planning, execution and release of complex technical projects.
  • Work with partners, product managers, and designers to solve challenging problems.
  • Collaborate with other engineers on the team to improve technology and apply best practices.
  • Implement step-wise technical migrations of our existing services and applications.
  • Own small to medium features or infrastructure projects from technical design through completion with little required guidance.
  • Independent contributor to their team. Work effectively across the codebase with appropriate guidance from code owners.
  • Make steady, well-paced progress without requiring frequent significant feedback from more senior engineers.
  • Compliance with all applicable laws and regulations
  • Other duties as assigned
Qualifications
  • 5+ years of professional software engineering experience, working with a variety of technologies, and have increasingly impactful accomplishments
  • Experience proposing, experimenting, and iterating, whether it be a new shiny technology or an arcane, ill-conceived data structure; our company may be new, but the health industry isn't!
  • Experience with technical contributions, improving the quality of what you create, and are excited to build fault‑tolerant, and scalable software systems.
  • Demonstrates solid understanding of the practical application of CS concepts within their team.
  • Consistently writes stable, correct, and maintainable code with little oversight; writes modular, adaptable code with guidance.
Bonus Points
  • Experience supporting libraries and writing in Python and Golang.
  • Experience owning observability stack tooling, e.g. Grafana, BigQuery, Kubernetes.
  • Experience working in data and engineering tooling, e.g. discovery libraries, data replication, data transfer tools, authentication, authorization libraries.

At Oscar, being an Equal Opportunity Employer means more than upholding discrimination‑free hiring practices. It means that we cultivate an environment where people can be their most authentic selves and find both belonging and support. We're on a mission to change health care -- an experience made whole by our unique backgrounds and perspectives.

Pay Transparency: Final offer amounts, within the base pay set forth above, are determined by factors including your relevant skills, education, and experience. Full‑time employees are eligible for benefits including: medical, dental, and vision benefits, 11 paid holidays, paid sick time, paid parental leave, 401(k) plan participation, life and disability insurance, and paid wellness time and reimbursements.

Reasonable Accommodation: Oscar applicants are considered solely based on their qualifications, without regard to applicant’s disability or need for accommodation. Any Oscar applicant who requires reasonable accommodations during the application process should contact the Oscar Benefits Team (accommodations@hioscar.com) to make the need for an accommodation known.

Artificial Intelligence (AI) Guidelines: Please see our AI Guidelines for the acceptable use of artificial intelligence during the interview process at Oscar.
