We need to output HTML fragment with sections: About the role? Actually we have "What to Expect", "Job Overview", "How You Will Contribute", "What You Will Bring", "Must-Have Requirements", "Nice-to-Haves". Also compensation info: base salary range. Should we include Pay section? Yes, we have salary range. Should we include Benefits? Not given specifics beyond "competitive compensation (salary and equity) and benefits." That's vague; we could include Benefits section? The rule: include a section ONLY when posting has real, specific content for it. "competitive compensation (salary and equity) and benefits." is vague but mentions benefits generally. Might be considered not specific enough. Safer to not create Benefits section unless specifics. Pay section we have salary range, so include Pay.
We need headings using for section headings: e.g., About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. But we can choose headings that match content: maybe "About the role", "Responsibilities", "Requirements", "Qualifications", "Skills", "Pay". However we must not repeat job title as heading. Use headings that reflect sections we have.
We need to map content:
- About the role: could be the introductory paragraph about Heron Power and what to expect. That's "What to Expect Heron Power is a startup..." plus maybe "Job Overview". Could combine.
- Responsibilities: "How You Will Contribute" bullet list.
- Requirements: "What You Will Bring" plus "Must-Have Requirements". Could separate: Qualifications (must-have) and Skills (nice-to-haves). But we have headings: Requirements, Qualifications, Skills. We'll decide.
Better: Use "About the role" for intro, "Responsibilities" for How You Will Contribute, "Requirements" for Must-Have Requirements, "Qualifications" for Nice-to-Haves? Actually qualifications often are must-haves. But we can follow typical: Requirements = must-have, Qualifications = nice-to-have, Skills = maybe scripting etc. However we have overlapping.
Simplify: Use sections: About the role, Responsibilities, Requirements (must-have), Nice-to-haves (maybe as Skills). Pay.
We must not create sections with filler. Ensure each heading has substantive content.
Let's extract content:
Intro: "What to Expect Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything. Our first focus goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron Power’s leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products over the past decade. We understand that no one individual knows everything. We will all learn a lot together and from each other. We strive to build a collaborative, enriching environment conducive to personal, technical, and career growth. You can expect to work in a dynamic and collaborative environment, driven by first principles engineering, solving difficult problems."
Job Overview: "The Systems Integration Engineer, SST & BESS Applications will own application-specific testing of Heron's solid state transformer (SST) across its core use cases: powering AI data centers, utility-scale BESS, and PV plants. That means bringing up hardware in the lab and at pilot sites, writing scripts to drive test equipment and power converters, and debugging performance against what each application demands, from MPPT performance and PPC/EMS/BMS communication to AI load smoothing and DC protection coordination. You will work hand in hand with the Systems Integration team: they own the SST platform; you own the applications."
How You Will Contribute bullet list:
- Own end-to-end application testing of a novel high C-rate battery pack (SuperBBU) with Heron's SST, validating ripple mitigation, backup capability, slew rates, and power-loss profiles.
- Support SST and utility-scale BESS integration testing at pilot sites, covering EMS-to-SST communication, black start and grid-forming coordination, charge/discharge cycling, and round-trip efficiency.
- Support integration testing of the SST with commercial off-the-shelf DAS, SCADA and EMS systems.
- Own Heron's first pilot deployments: review field performance, identify feature gaps, and work with SW/FW teams to turn findings into product improvements.
- Write and maintain Python-based test automation to command power converters, sequence tests, log data, and turn manual procedures into repeatable automated loops.
- Safely operate power converters, chillers, contactors, and protection hardware, and set up cabling, instrumentation, and data acquisition for high-power test runs.
What You Will Bring (must-have):
- 5+ years of hands-on experience in power electronics, energy storage, EV, grid, or a comparable hardware-intensive environment.
- Strong grasp on DC circuit fundamentals: resonances, parasitics, slew rates, and inductive spikes.
- You can correlate test data with simulation results.
- Strong scripting and test-automation skills to drive instruments and power converters and to log and analyze data.
- Working knowledge of power conversion and battery systems: inverters and converters, BMS, DC pre-charge, contactors and protection, and thermal and cooling loops.
- Comfort with lab instrumentation (oscilloscopes, power analyzers, DAQ systems) and comms protocols such as CAN and Modbus TCP.
- Scrappy mindset: you get things done with a hundred hurdles in front of you.
Nice-to-Haves:
- Experience with solid state transformers or grid-forming inverters.
- Familiarity with utility-scale BESS commissioning, grid-support functions, or EMS integration.
- Prior experience in systems-level testing of power electronics or energy storage products
- Hands-on experience with circuit and system simulation tools such as LTspice, Simscape, or PLECS.
- If you are passionate about the energy transition and enjoy working at the frontier of power electronics and grid integration, we would love to hear from you.
Pay: "Heron Power provides competitive compensation (salary and equity) and benefits. The base salary range for this role is from $140,000 to $185,000K." Note: "$185,000K" seems typo maybe $185,000. We'll keep as given.
We should not include navigation etc.
Now produce HTML fragment:
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should use those exact headings when we have content. If we don't have content for a heading, we should not include it. So we need to map our content to those headings.
Thus we need sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Pay (maybe Benefits if we have). We have no Schedule.
We need to decide what goes where.
About the role: intro + job overview? Could be combined.
Responsibilities: How You Will Contribute.
Requirements: Must-Have Requirements.
Qualifications: Nice-to-Haves? Or maybe Qualifications = Must-have? But we already used Requirements for must-have. Qualifications could be nice-to-haves.
Skills: maybe the specific technical skills like scripting, instrumentation, etc. But we already have those in must-have. Could split: Requirements = experience years, Qualifications = domain knowledge, Skills = technical skills. However we risk duplication.
Better: Use About the role (intro+job overview), Responsibilities (How You Will Contribute), Requirements (Must-Have Requirements), Qualifications (Nice-to-Haves), Skills (maybe we could list specific skills like Python, CAN, Modbus, oscilloscopes etc). But we already have those in must-have; we could move some to Skills.
Let's extract skills: Strong scripting and test-automation skills, comfort with lab instrumentation, comms protocols, etc. Those are skills.
Thus:
- About the role: intro + job overview.
- Responsibilities: How You Will Contribute bullet list.
- Requirements: 5+ years experience, strong grasp DC fundamentals, correlate test data, scrappy mindset.
- Qualifications: Working knowledge of power conversion and battery systems, comfort with lab instrumentation and comms protocols? Actually those could be skills. Hmm.
Maybe better: Requirements = must-have (experience, fundamentals, scripting, knowledge, instrumentation, scrappy). Qualifications = nice-to-haves. Skills = maybe we could list specific technical skills like Python, CAN, Modbus, LTspice etc. But we risk thin sections.
Given instruction: "Prefer a few substantive sections over many thin ones." So better to have fewer sections. Let's use About the role, Responsibilities, Requirements, Qualifications, Pay.
We can put all must-have under Requirements, nice-to-have under Qualifications, and Pay separate.
Thus:
for section headings: e.g., About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. But we can choose headings that match content: maybe "About the role", "Responsibilities", "Requirements", "Qualifications", "Skills", "Pay". However we must not repeat job title as heading. Use headings that reflect sections we have.

But the instruction says use headings like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. It didn't say we must use exactly those, but we should use those headings for sections. It says: use for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should use those exact headings when we have content. If we don't have content for a heading, we should not include it. So we need to map our content to those headings.

Heron Power provides competitive compensation (salary and equity) and benefits. The base salary range for this role is from $140,000 to $185,000.
We corrected the typo: removed extra K. Check for any boilerplate removed: we removed "Join us in accelerating the electrification of everything at Heron Power." That's maybe part of intro but could be kept? It's a call to action, maybe considered boilerplate? It's not navigation/legal/EEO. It's a closing statement. Might be okay to keep but could be considered fluff. The instruction: Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. That line is not those. It's a motivational sentence. Could keep. But we already have intro ending with "You can expect to work in a dynamic and collaborative environment, driven by first principles engineering, solving difficult problems." The "Join us..." is extra. Might keep as part of About the role? Could add at end of
