Space Systems Expert

Alpheva; United States; Remote; USD 262,000 - 331,000; Part time

Job summary

Alpheva is seeking a senior space systems engineer for remote, project-based work focused on orbital mechanics, spacecraft subsystems, mission assurance, and ground operations. You will review responses for correctness, craft reference answers, and define scoring criteria grounded in rigorous spacecraft engineering standards.

The role requires senior judgment, clear traceability, and the ability to justify corrections with evidence. Engagements are variable by project and pay is hourly.

Qualifications

• 7+ years of substantive experience in space systems engineering.
• Ability to exercise senior-level judgment in orbital mechanics, spacecraft subsystems, mission assurance, and ground operations.
• Ability to write precise reference answers, assess competing approaches, and justify corrections with traceable evidence.

Responsibilities

• Review model responses and worked examples for correctness against orbital mechanics and mission constraints.
• Write reference answers and scoring criteria grounded in spacecraft systems engineering.
• Explain consequential errors, evidence gaps, and rationale behind corrections.

Job description

Bring senior space systems expertise to AI evaluation projects focused on orbital mechanics, spacecraft subsystems, mission assurance, and ground operations.

Review model responses and worked examples for incorrect system assumptions, missing operational constraints, and unsupported analytic confidence. Assess whether the reasoning meets professional standards for the stated task.

Write reference answers and scoring criteria grounded in orbital mechanics, spacecraft subsystems, mission assurance, and ground operations. Explain consequential errors, evidence gaps, and the reasoning behind your corrections.

This is remote, project-based contract work. Scope, hours, and assignments depend on project matching; the listed hourly range applies to matched work.

Requirements

• 7+ years of substantive experience in space systems engineering.
• Demonstrated senior-level judgment in orbital mechanics, spacecraft subsystems, mission assurance, and ground operations, with substantial responsibility for reviewing or delivering this work.
• Ability to write precise reference answers, assess competing approaches, and justify corrections with traceable evidence.
