Principal Engineer (Backend/.NET) choosing between FNZ, Autodesk, and MedMetrix — looking for engineering + career advice

Hi everyone,

I’m a Principal Software Engineer (backend, .NET, AWS) currently working in India (~38.8 LPA fixed + 10% bonus), and I’m evaluating a few opportunities. I’d really appreciate insights specifically from an engineering, system design, and long-term career growth perspective.

Here are the options:

MedMetrix

₹58 LPA fixed
EST shift (5:30 PM – 2:30 AM IST)
From what I understand, work may be more service/operations-heavy

Autodesk

₹40 LPA fixed + 10% bonus
~$30K stock over 4 years + ₹3L joining bonus
Strong product company, but role is Senior Software Engineer (down-level from my current Principal role)

FNZ (in process)

Expecting ~₹55L+
FinTech domain (wealth management platform)
Trying to understand if the work is core product engineering vs client delivery

What I care about:

Backend/system design challenges at scale
Clean architecture, distributed systems exposure
Long-term growth (next 3–5 years)
Avoiding roles that are mostly operational/support-heavy

Questions:

How is the engineering quality and system design exposure at FNZ vs Autodesk?
Does FNZ involve significant client-driven/customization work, or is it core product engineering?
For someone already at Principal level, is taking a down-level role (Autodesk SSE) worth it for brand + learning?
How bad is long-term night shift (MedMetrix) from your experience in terms of productivity and growth?
Which option would set me up better for high-quality backend/product roles in the future?

Would really appreciate insights from people who have worked in these companies or similar environments.

Thanks!
