Role:

Auto-IT builds the dealer management systems that run automotive, agricultural, and equipment dealerships across Australia, New Zealand, and Asia - part of the Perseus Operating Group within Constellation Software, with engineering across Australia, New Zealand, Pakistan and India.

We run a mature SQL Anywhere 17 production database, and we are migrating it to PostgreSQL 18. Years of dealership data sit in it, and query performance and schema quality translate directly into whether a service advisor waits three seconds or thirty. You will spend your time making the current database measurably better while helping build and prove the path to the next one.

You will need real technical depth in backup, recovery, availability, and the infrastructure the database runs on, and you will work closely with the DevOps and Infrastructure team across all of it. Your primary focus, though, is performance and improvement - how the data is modelled, how it is indexed, and how quickly we can query it.

What you'll do

• Profile and improve the performance of our production SQL Anywhere 17 database - identify the queries that hurt, read the execution plans, and fix them at the query, index, or schema level.

• Establish baselines and instrumentation so performance can be measured, and so regressions are caught before customers report them.

• Improve the schema over time: constraints, data types, and indexing that enforce correctness in the database instead of leaving it to the application layer.

• Work alongside application developers on the SQL embedded in our PowerBuilder and .NET codebases, and help them write queries that hold up under production data volumes.

• Translate schema and SQL from SQL Anywhere 17 to PostgreSQL 18, and reason carefully about where the two dialects differ in ways that change results, not just syntax.

• Build and extend the comparison harnesses that prove a migrated query returns what the original returned, against real data.

• Plan and execute data migration and reconciliation - extraction, load, validation, and the evidence that nothing was lost or quietly altered.

• Contribute to the technical direction of the migration, and to the design decisions that are still open.

• Document what you learn. Much of what makes this database behave the way it does is currently undocumented.

Technical environment

SAP SQL Anywhere 17 - query plans and optimiser behaviour · index selection · server and cache tuning · SQL Remote replication · dbunload, dbvalid, dbbackup · embedded SQL within PowerBuilder

PostgreSQL 18 - Azure Database for PostgreSQL Flexible Server · EXPLAIN (ANALYZE, BUFFERS) · B-tree, partial, expression, and GIN indexing · partitioning · autovacuum and bloat · extensions including pgvector

Migration - the move from SQL Anywhere 17 to PostgreSQL 18 is underway and its technical direction is still being set. You are expected to help shape that direction, not only implement against it: the design decisions that remain open, how we validate the result, and the standard of evidence we hold it to.

Application context - PowerBuilder (Units, Equip) · .NET and Blazor Server (Enable) · platform tooling

Platform and tooling - Microsoft Azure · Git · TeamCity · containerised SQL Anywhere instances used as the reference for expected results · scripting in Python or PowerShell

What you'll bring

Essential - Deep, practical SQL. Demonstrable performance tuning experience on a production relational database, with real examples of queries you have diagnosed and fixed, and the ability to explain why the fix worked. Relational schema design, including indexing strategy and the tradeoffs it involves. Comfort reading and reasoning about execution plans. A habit of proving changes with evidence. Working knowledge of database backup, recovery, and availability, and of the infrastructure a production database depends on.

Scripting ability for the automation this work needs. Clear English, and the communication discipline distributed work demands.

Desirable - PostgreSQL specifically · SAP SQL Anywhere or Sybase ASA · heterogeneous database migration between dialects · replication, whether SQL Remote or PostgreSQL logical replication · Azure Database for PostgreSQL Flexible Server · exposure to PowerBuilder codebases · the automotive, agricultural, or equipment dealership domain.
