What I need help with: Run mock recruiter intro calls (30–45 minutes) and give direct feedback Improve my 60–90 second “Tell me about yourself” to be clear and confident Help me structure answers for common screening questions (role fit, strengths/weaknesses, project impact, conflict, availability, salary expectations) Polish my English phrasing so it sounds natural and concise Optional: create a short “answer bank” I can practice (bullet notes + sample responses) Requirements: Strong spoken English 3–5+ years technical background (software engineering or highly technical recruiting) Comfortable discussing real engineering topics at a high level (APIs, databases, cloud, debugging, system design basics) Please include: - A short note about your technical background - Your rate per 1 interview with me I prefer to start with a paid 30-minute trial mock call, then continue weekly if it’s a good fit. Cheers

Translate Technical PDFs into German

I need a precise, native-level German rendition of several technical/scientific documents that I currently have only as PDFs. Accuracy of terminology is paramount; the text covers specialised concepts and data that must read naturally to a German-speaking engineer or researcher without losing any nuance. You will receive the original PDFs and return the translated content in a format that lets me edit and reuse it easily—Word (.docx) or an equivalent editable file is fine as long as the structure mirrors the source PDF. Acceptance criteria 1. Technical vocabulary is rendered with correct, industry-standard German terms. 2. All tables, figures and captions stay in their original positions and sequence. 3. Final file opens without layout issues and matches the pagination of the source.

STAR-CCM+ + TAITherm Cabin HVAC Thermal Comfort Debug/Fix

Automotive Cabin Heating Thermal Comfort Simulation Fix (STAR-CCM+ .sim + TAITherm Human Thermal / Berkeley Comfort) We are looking for an engineer who can run and troubleshoot an automotive cabin heating thermal comfort simulation using: - Simcenter STAR-CCM+ (.sim) for cabin airflow/temperature fields - TAITherm Human Thermal / HTE + Berkeley Comfort for occupant comfort outputs Task goal (what you need to deliver) We have a simplified cabin model. Under a cold ambient heating scenario, the current results are abnormal: occupant thermal sensation/comfort improves briefly and then becomes colder again (e.g., TS drops toward -1 and continues decreasing). We need you to diagnose the root cause and correct the model setup/coupling/mapping so the outputs are physically reasonable. Target requirements (high level): - Transient duration: 1800 s (30 min) - Monitoring temperatures: foot/foot-vent zone around ~35°C, head point around ~20°C (exact monitor definitions will be shared privately) - Comfort trend: overall thermal sensation & comfort must be normal/stable (after heating ramps up, it should not “get colder again”) What we expect from you - Identify why comfort trend becomes colder (typical causes include MRT/radiation boundary, incorrect field-to-human mapping of Ta/Tr/velocity/RH, initialization/restart issues, boundary leakage on cut surfaces, etc.) - Provide corrected settings + clear explanation of what was wrong and what you changed - Provide plots/outputs for monitoring temperatures + comfort metrics (TS/PMV/PPD or equivalent) Required experience (please do NOT apply if you don’t have this) - Hands-on experience with STAR-CCM+ transient cabin HVAC/thermal - Hands-on experience with TAITherm Human Thermal / Berkeley Comfort (not only CFD) - Ability to actually run the case (access to software/licenses or a workable setup) Confidentiality Due to confidentiality, we will share the detailed model files and full requirement document after you confirm capability. Please answer these in your proposal: 1) Have you used TAITherm Human Thermal / HTE + Berkeley Comfort in real projects? Share 1–2 lines of what you did (no confidential details). 2) Do you have access to STAR-CCM+ and TAITherm comfort/human modules to run the model? (Yes/No) 3) List your top 3 likely causes when cabin heating comfort “gets colder again” (keywords are fine: MRT/radiation, mapping, restart/initialization, boundary condition, cut-surface leakage, etc.) 4) What is your estimated time (days) to deliver corrected results + explanation? 5）Tell me how much you would charge for my task. —————————— Keywords: STAR-CCM+ .sim, Simcenter, cabin HVAC heating, automotive thermal management, TAITherm 2020, ThermAnalytics, Human Thermal Model, Human Modeling Extension (HTE), Berkeley Comfort Model, thermal sensation (TS), PMV, PPD, MRT (mean radiant temperature), radiation boundary, coupling/mapping, transient 1800s, monitoring points, HDF5 .tdf, .vfs .slf .tlf - Simcenter STAR-CCM+ (Transient / CHT / Radiation) - TAITherm / RadTherm (Human Thermal / HTE) - Thermal Comfort / Berkeley Comfort / PMV-PPD - Automotive HVAC / Cabin Thermal Management - CFD Post-processing / Data analysis (HDF5)
