About the role

This is a Senior Level role in the Technology field (Software engineering) at Oscar Health. Senior roles usually expect substantial experience, ownership of results and often the ability to guide others.

We could not match this job title to one occupation in the official wage statistics, so no pay estimate is shown. Pay is not in the source listing; ask the employer for the range and compare in the 240 job niches.

Does the pay work here? (estimate)

Gross salary a year Filing State income tax rate %

Estimate for a wage earner: 2026 federal brackets and standard deduction (IRS), Social Security 6.2% up to $184,500, Medicare 1.45% (+0.9% above $200,000 single / $250,000 married), and a state rate you set; set your own state tax rate.

How to prepare and behave

This is editorial guidance, not information from the employer.

Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
Be honest about gaps; say what you did to learn and how fast you can close them.
Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
Send a short thank-you message within a day, mentioning one thing you discussed.
Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

The city

The job is in Los Angeles, CA. Below is what the official statistics say about living and working there.

How Los Angeles compares. Among the 145 largest places in California, Los Angeles is #1 by population, #141 for homeownership (#1 = highest), #121 for household income (#1 = highest), #39 for rent (#1 = cheapest). Its county, Los Angeles County, is #7 of 58 counties for average pay ($83,554).

The place in numbers

Los Angeles has 3,857,263 residents (ACS 2020–2024), about 9.8% of the population of California. It covers 471 square miles of land, which works out to roughly 8,198 people per square mile. The median age is 37.2, about the same as the state median (37.2 against 37.9).

Housing

The median gross rent is $1,933 a month (rent plus utilities), 5% below the state median ($1,933 against $2,036). Over a year that is 28.3% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $921,200, which is 11.2 times the median household income ($81,939); a ratio above 5 usually means buying is out of reach without savings or a second income. 36.0% of households own their home, 36% below the state average (36.0% against 55.9%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.

Work and pay

The Los Angeles-Long Beach-Anaheim, CA metropolitan area has 6,271,560 jobs in the BLS wage survey, and the median pay across all occupations is $55,850 a year, 10% above the national median ($55,850 against $50,980). The biggest occupation groups are office and administrative support (702,480 jobs, median $52,710); food preparation and serving related (588,660 jobs, median $38,460); healthcare support (537,460 jobs, median $35,630). The area is most specialised in arts, design, entertainment, sports, and media (2.2 times) and healthcare support (1.7 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($136,490) and legal ($128,110). In 2026M09 the unemployment rate of Los Angeles County was 4.5%. 66.4% of residents aged 16 and over are in the labour force. The city lies in Los Angeles County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 59.8% drive alone, 6.1% use public transit, 3.2% walk, 19.5% work from home. 22.2% of workers commute 45 minutes or more, 14% above the state average (22.2% against 19.4%).

People and education

38.5% of adults aged 25 and over hold a bachelor's degree or higher, 4% above the state share (38.5% against 37.1%). 35.7% of residents were born outside the United States, 32% above the state share (35.7% against 27.0%). The poverty rate is 16.6%, 38% above the state rate (16.6% against 12.0%).

Climate

The warmest month is Aug, averaging 75°F (23.9°C), and the coolest is Dec at 53°F (11.8°C). About 332 mm (13 inches) of precipitation falls in a year; Feb is the wettest month (75 mm) and Jun the driest (1 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.

Nearby cities to compare

Closest cities in this guide: Santa Monica (5 miles, rent 24% higher); Inglewood (6 miles, rent 8% lower); Hawthorne (8 miles, rent 8% lower); Burbank (13 miles, rent 13% higher). Rent differences are against Los Angeles; use the Compare tab to put any two cities side by side.
