Ilsan Tijhuis

I am an Engineering Manager with a strong software engineering background, currently leading multiple teams in the iGaming industry. My career has grown from hands-on development through team lead and engineering lead roles to shaping technical strategy and building effective teams. I care about delivering reliable software at scale and creating an environment where engineers can do their best work.


Experience

Engineering Manager

Bally's Intralot

I was promoted to Engineering Manager at Bally's Intralot, where I oversee multiple teams working on iGaming products. My primary focus is on ensuring teams deliver effectively — from removing blockers and keeping projects on track to contributing to the technical strategy for our domain. As one of the core domains in the business, keeping our services resilient and scalable enough to handle the demands of a live online casino is central to the role.

May 2025 - Present

Engineering Lead

Bally's

I worked for Bally's as an Engineering Lead, focusing with my team on services responsible for anything Player Account and Wallet related. One of the key projects was the deprecation of an old legacy front-end service, replacing it with more modern scalable solutions.

January 2024 - April 2025

Team Lead

Bally's

Gamesys got acquired by Bally's, and I was asked to form a new team responsible for migrating all services using Apigee (API management) off to secure alternatives. This involved working together with other teams and architects to come to solutions each and everyone was happy with. It also meant that work was being done across the whole business, which came with challenges due to different release processes, availability, scalability and performance requirements for the APIs and services using them. This project was finished in December 2023.

October 2021 - December 2023

Team Lead

Gamesys

After working about a year and half as Software Engineer I was given the opportunity to grow my career and become a Team Lead at Gamesys. My team was responsible for AAA (Authorization, Authentication and Access-Control), the login journey and password reset journey. Completed during this time the rollout of the new password reset microservice over multiple jurisdictions in the world. The team also migrated many legacy services over to scalable, fast-performing new microservices while adding new features requested by the business.

January 2020 - October 2021

Software Engineer

Gamesys

I started at Gamesys as a Software Engineer before my promotion to Team Lead. My daily activities included working in an Agile team on different (micro) services, from development till release. Many services which could only be released manually were upgraded to be able to release automatically to live. Worked on services related to KYC and also started to create a new password reset microservice.

September 2018 - January 2020

Software Developer

Topicus

At Topicus I was responsible as a Scrummaster and developer to develop software for healthcare companies and the public sector. Part of my job also consisted of doing dev-ops to keep applications running. Mostly I was programming in JVM languages, but also part of my job was to try out and work with the latest techniques and languages.
