ABOUT ROCKET LAB

Rocket Lab is the end-to-end space company building rockets, spacecraft, and critical subsystems that keep the world connected, protected, expand humanity’s reach to the Moon, Mars, and beyond. We move fast, build real hardware for meaningful missions, and make the impossible routine. Come shape the future with us.

SPACE SYSTEMS

Rocket Lab’s Space Systems division builds complete spacecraft, precision payloads to the components and subsystems that allow them to thrive in space including solar panels, flight software, star trackers, optical systems, separation systems, and radios.

The Space Systems division has enabled more than 1,700 missions, ranging from interplanetary exploration, in-space manufacturing to national security and defense initiatives. We have built spacecraft, payloads, and components for missions to the Moon and Mars, working with partners including NASA, the Space Development Agency, and the U.S. Space Force. Whether it’s a single high-performance spacecraft, constellation, or the vertically integrated components that help get to space — our Space Systems division is empowering the boldest and most ambitious space missions.

SENIOR SOFTWARE SYSTEMS ENGINEER II

Rocket Lab Optical Systems solves mission-critical space domain and Intelligence, Surveillance, and Reconnaissance challenges for Department of Defense and Intelligence Community customers. Our vision is to revolutionize the space-based payload market with innovative and novel designs for space, terrestrial, and airborne environments.

• Verify the correct software build and configuration are under test, confirming the as-tested configuration matches the intended verification
• Support authoring, derivation, and verification of software and firmware requirements, and maintain requirements traceability throughout the development lifecycle, addressing conflicts or gaps
• Participate in technical interchange meetings (TIMs) and represent the organization in project discussions with internal stakeholders and external partners
• Mentor other engineers on systems engineering, requirements, and verification and validation (V&V) methodologies
• Ability to support travel or off-site work, as needed

QUALIFICATIONS YOU’LL BRING AS SENIOR SOFTWARE SYSTEMS ENGINEER II:

• Demonstrated experience working with minimal supervision in complex projects
• Excellent communication and interpersonal skills with the ability to collaborate with multidisciplinary teams and explain complex implementation processes to other organization members

This position may require prolonged periods of sitting, standing, walking, computer work, and occasional exposure to moderate levels of noise, dust, and fumes in production areas.

WHAT TO EXPECT 

We’re on a mission to unlock the potential of space to improve life on Earth, but that’s not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work, and out-pace. We pride ourselves on having each other’s backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.

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 Tucson, AZ. Below is what the official statistics say about living and working there.

How Tucson compares. Among the 80 largest places in Arizona, Tucson is #2 by population, #76 for homeownership (#1 = highest), #71 for household income (#1 = highest), #14 for long commutes (#1 = fewest). Its county, Pima County, is #3 of 15 counties for average pay ($61,936).

The place in numbers

Tucson has 547,073 residents (ACS 2020–2024), about 7.4% of the population of Arizona. It covers 242 square miles of land, which works out to roughly 2,259 people per square mile. The median age is 34.6, 11% younger than the state median (34.6 against 39.0).

Housing

The median gross rent is $1,145 a month (rent plus utilities), 26% below the state median ($1,145 against $1,543). Over a year that is 24.1% 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 $266,200, which is 4.7 times the median household income ($57,073). 51.9% of households own their home, 23% below the state average (51.9% against 67.4%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.

Work and pay

The Tucson, AZ metropolitan area has 389,630 jobs in the BLS wage survey, and the median pay across all occupations is $47,760 a year, 6% below the national median ($47,760 against $50,980). The biggest occupation groups are office and administrative support (46,550 jobs, median $44,920); food preparation and serving related (36,210 jobs, median $34,990); sales and related (33,700 jobs, median $36,070). The area is most specialised in architecture and engineering (1.5 times) and protective service (1.3 times), where the share of workers is above the national share. The best-paying groups with at least 5,000 jobs are management ($100,780) and computer and mathematical ($97,560). In 2026M09 the unemployment rate of Pima County was 4.8%. 60.7% of residents aged 16 and over are in the labour force. The city lies in Pima County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 68.0% drive alone, 2.3% use public transit, 2.6% walk, 13.8% work from home. 7.9% of workers commute 45 minutes or more, 45% below the state average (7.9% against 14.2%).

People and education

31.1% of adults aged 25 and over hold a bachelor's degree or higher, 7% below the state share (31.1% against 33.3%). 13.4% of residents were born outside the United States, 4% above the state share (13.4% against 13.0%). The poverty rate is 18.9%, 51% above the state rate (18.9% against 12.5%).

Climate

The warmest month is Jun, averaging 82°F (27.5°C), and the coolest is Dec at 45°F (7.4°C). About 323 mm (13 inches) of precipitation falls in a year; Jul is the wettest month (82 mm) and May the driest (4 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: Catalina Foothills (10 miles, rent 23% higher); Drexel Heights (10 miles, rent 17% higher); Tanque Verde (11 miles, rent 18% higher); Flowing Wells (13 miles, rent 10% lower). Rent differences are against Tucson; use the Compare tab to put any two cities side by side.
