A quick note as you apply We kindly ask that you apply through the website rather than emailing careers@modulate.ai.
For the questions “Your fit for the role,” “Your values/goals,” and “Why Modulate?” on our application form, we kindly ask that you focus your responses on experiences and motivations that directly relate to the role.
Please avoid including details that would reveal protected demographic information (such as race, age, gender, ethnicity, or sexual orientation), as we strive to assess all candidates equitably and without bias.
We also want to hear your authentic voice. While it can be helpful to use tools to support your thinking, we ask that your responses reflect your own perspective.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
