about the role
remote position, Romania only
We're looking for a Lead Solutions Architect to shape the technical approach of a 40-week, milestone-based program for one of our clients, a multi-brand software company: converting its applications to a target .NET version and migrating its MSSQL and Oracle databases, including change-data-capture (CDC) feeds, to PostgreSQL.
There are two architect seats on the program: one focused on blocker resolution and the application conversion approach, the other on converting inline and embedded SQL (“Lane C”) through to hypercare.
You'll be the senior technical voice in front of the customer.
what you'll do
- Lead the assessment and define the modernization strategy, deployment path, cutover order and rollback route for each application.
- Resolve technical blockers early and document a remediation path and resulting platform decisions for each.
- Define the application conversion and testing approach to the target .NET version.
- Lead the conversion of inline and embedded SQL from MSSQL/Oracle dialects to PostgreSQL.
- Agree performance and availability targets with the customer, based on legacy baselines.
- Guide engineers through parity, load testing, rehearsals and cutovers.
- Support hypercare and knowledge transfer to the customer’s operations and DBA teams.
requirements
must have skills:
- 10+ years in software engineering, with several years as a solutions or technical architect.
- Senior .NET architecture experience and hands-on legacy modernization (.NET Framework to modern .NET).
- Deep SQL across MSSQL and/or Oracle and PostgreSQL.
- Experience refactoring SQL embedded in application code and data-access layers.
- Track record of designing cutover and rollback strategies for production systems.
- Customer-facing technical leadership and confident decision-making.
- Fluent English, comfortable working directly with client engineers and stakeholders.
nice to have skills:
- Experience with CDC pipelines (AWS Kinesis, Kafka).
- Traffic-replay or shadow-testing approaches for parity validation.
- AWS experience, including managed PostgreSQL.
- Experience with automated SQL conversion tooling.
