NestJS, NodeJS, Vue

Redis, SQL Server & Snowflake

AWS (cloud-first architecture)Strong .NET Architects who've worked in modern cloud and micro-services environments, or who can operate confidently across Node/TypeScript ecosystems, are absolutely encouraged to apply.

What matters most is architectural depth, SaaS scalability experience, and strong engineering principles.

You'll:

Design large-scale, high-performance SaaS architectures

Lead microservices and event-driven design initiatives

Champion DevOps-aligned architecture patterns

Work across distributed/offshore teams

Operate comfortably at both strategic and deep technical levels

Influence AI architecture and modern data practices

3-5+ years in a Software Architect role

Strong engineering background (C#/.NET or modern JS/TS stacks)

Experience within mature B2B SaaS environments

Deep knowledge of cloud architecture (ideally AWS)

Experience with microservices, event-driven systems

Strong understanding of OLAP, OLTP, ETL & data warehousing

DevOps-first mindset

Excellent stakeholder engagement skills

Interested?

If you're an Architect who wants real influence in a scaling SaaS environment - without being boxed into one technology - this is a strong opportunity.
