Senior Software Engineer (Onsite)
for section headings.
We need to use - for any list of duties/requirements/benefits.
We need
for prose.
We must not repeat job title as heading (not given). No Job ID.
We must preserve all substantive info.
We must not invent or summarize away detail.
We must not include sections with filler like "commensurate with experience". Not present.
We need to decide sections:
- About the role (maybe company overview). Could be "About the role" or "About RTX BBN Technologies". Use heading "About the role". Provide prose summarizing company description and role context.
- Responsibilities: list from "Responsibilities will include but are not limited to:" and also "What You Will Do" maybe combine? But we need to avoid duplication. We'll include responsibilities as list.
- Requirements: security clearance, citizenship, etc. Also maybe "U.S. Citizen, U.S. Person, or Immigration Status Requirements". We'll list.
- Qualifications: Must Have and Preferred.
- Skills: maybe we can extract from qualifications: Embedded C/C++, RTOS, etc. But we could put under Qualifications.
- Benefits: from "What We Offer" and benefits list.
- Pay: salary range.
- Schedule: maybe not present; we have flexible work schedules mentioned under benefits but not schedule specifics. Probably omit.
We must not create empty sections.
Let's extract details.
Company description: "At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Join us and help shape the future of aerospace and defense. RTX BBN Technologies is an organization which values work/life balance and encourages lifelong learning of new technologies. For over 70 years, scientists and engineers in diverse disciplines at RTX BBN Technologies have collaborated to solve real-world problems through research, exploration, development and prototyping. We challenge the status quo, pioneer new technologies, and create transformative solutions."
We can put that under About the role.
Responsibilities: from "Responsibilities will include but are not limited to:" list:
- Linux and VxWorks real-time software development on a wide range of embedded multi-threaded platforms,
- integrating with custom hardware,
- implementation of high-performance embedded solutions,
- middleware,
- and implementing control, detection, and tracking algorithms developed by the systems engineering team.
Also "What You Will Do" list:
- Design, develop, implement, test, debug and integrate high performance embedded real-time software within heterogenous systems composed of multiple processor types and FPGAs, with external sensor and control interfaces for deployed DoD real-time software systems hosted on embedded hardware.
- Collaborate with a cross-functional team testing your contributions and analyzing performance.
- Integrate components you develop into a larger system in preparation for real world testing and deployment.
- Teaching, coaching, and mentoring less experienced staff.
- Contributing to proposals as well as preliminary and critical design reviews.
- Ability to travel up to 15%
We could combine both into responsibilities list, but ensure not duplicate. We'll include all distinct items.
Requirements: security clearance active and transferable Secret, U.S. citizenship required, Onsite, maybe also "U.S. Citizen, U.S. Person, or Immigration Status Requirements". Also "Active and transferable U.S. government issued security clearance is required prior to start date." "U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance". "Security Clearance Type: DoD Clearance: Secret". "Security Clearance Status: Active and existing security clearance required on day 1". Also maybe "Position Role Type: Onsite". We'll list.
Qualifications Must Have:
- Typically requires a degree in STEM and minimum 5 years prior relevant experience or an Advanced Degree in a related field and minimum 3 years of experience or in absence of a degree, 9 years of relevant experience.
- Active and transferable Secret U.S. Government Security Clearance is required on day one.
- Experience including at least two of the following:
- Embedded C/C++ Software,
- High Performance Computer Systems,
- Embedded Real-Time Sensors and Control Applications,
- Software Architecture Design and Implementation.
- Experience using embedded Real Time Operating Systems (RTOS) (e.g., Green Hills, Integrity, Wind River VxWorks, Linux, etc.)
- Experience developing complex systems involving the integration of hardware, firmware, and software.
Qualifications We Prefer:
- Ada programming language.
- Proficiency using C/C++.
- Familiarity with digital signal processing algorithms and software.
- Knowledge of linear algebra concepts.
- Experience using the VSIPL high performance vector library or another vector processing library.
- Proficiency in MATLAB and/or optimizing algorithms in C/C++.
- Experience with real-time processing optimization.
Skills: maybe we can list from qualifications but we could just treat as part of Qualifications.
Benefits: from "What We Offer":
- robust total rewards package with compensation; healthcare, wellness, retirement, and work/life benefits; career development and recognition programs.
- parental (including paternal) leave,
- flexible work schedules,
- achievement awards,
- educational assistance and child/adult backup care.
- Also later: medical, dental, vision, life insurance, short-term disability, long-term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, Employee Scholar Program, parental leave, paid time off, and holidays.
- annual short-term and/or long-term incentive compensation programs depending on level.
We'll list benefits as bullet points.
Pay: salary range: 86,800 USD - 165,200 USD.
Schedule: not explicit; we have flexible work schedules under benefits but not schedule. We'll omit Schedule section.
Now produce HTML.
We need to wrap sections in

We'll start with a short p for metadata: maybe include date posted and location? The instruction: "Do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it." So we can include a
with date posted and location.
Let's craft:
Posted: 2026-09-16 • Location: Middletown, RI (Onsite)
Then sections.
We'll need to ensure we don't repeat info unnecessarily.
