Job description
Senior Software Engineer
Context
Takes full technical ownership, leading several technical complex designs. Contributes to development / change of sub-modules; responsible for results of sub-modules.
Works at Train level. Interfaces with other sectors in complex environment, may require negotiation.
Understands the contribution of other domains to the product; operates on module level and oversees the relations on function level. Takes end -to-end view, taking into account impact on other areas (e.g. research, customer, marketing).
Structural troubleshooting capabilities on functional level and manages many technical uncertainties at sub-module level and develops creative solutions to solve uncertainties. Can take responsibility for customer problems (end-customer/sectors in Operations), coming up with solutions for specific issues. Represents the competence in Product Development Cycle.
Masters a field and WoW in own function. Has visible impact in department or groups in other disciplines. Based on in-depth expertise in own module/technical discipline, finds solutions that are not obvious for others. Looks forward and acts proactively ( e.g. raising risks).
As a Technical Lead Designer, steers the work of 6-10 engineers.
Designs, develops, tests and integrates software for ASML s machines and applications. Implements analytics, data, control and algorithm applications that give ASML customers the power to reach optimal performance during manufacturing.
