I've spent the last 15 years building engineering teams around systems that have to make good decisions fast and at scale. Most recently at Lyft, where I led the mapping organization — 30+ engineers across five countries — and we moved more than 96% of rides off Google Maps onto our own mapping product. Before that I worked on machine learning and conversational AI at Microsoft Bing, and I did a PhD on learning in heterogeneous robot groups, which is a long way of saying that distributed decision-making has held my attention for a while. <p style="border:0px solid rgb(229,231,235);font-family:'Titillium Web', sans-serif, Inter, Arial, Helvetica, sans-serif;margin:0pt 0px;color:rgb(66,66,66);font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);line-height:1.38;">What pulled me to flexa is that it's the same class of problem with something physical at the other end. We dispatch energy of the Enpal customer fleet in real time against energy markets. If our infrastructure is a few seconds late or a few percent off, customers lose money and the grid gets less flexibility than it could have had. That makes cloud engineering a first-order product concern here rather than a supporting function — which is why this role sits close to the decisions that actually matter. <p style="border:0px solid rgb(229,231,235);font-family:'Titillium Web', sans-serif, Inter, Arial, Helvetica, sans-serif;margin:0pt 0px;color:rgb(66,66,66);font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);line-height:1.38;">How I work: I'd rather hand you the whole problem, context and constraints included, than a ticket. I care that engineers can see the consequences of what they build, and I'll be direct with feedback and expect the same back — the fastest way to lose a year is for everyone to stay polite about an architecture that isn't working.<p style="border:0px solid rgb(229,231,235);font-family:'Titillium Web', sans-serif, Inter, Arial, Helvetica, sans-serif;margin:0pt 0px;color:rgb(66,66,66);font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);line-height:1.38;"> <p style="border:0px solid rgb(229,231,235);font-family:'Titillium Web', sans-serif, Inter, Arial, Helvetica, sans-serif;margin:0pt 0px;color:rgb(66,66,66);font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);line-height:1.38;">You won't find everything already built. Some of it is greenfield, some of it needs replacing, and you'll have real influence over which is which. If that sounds like your kind of problem, I'd like to hear from you — and if you're not sure your profile is a perfect match, apply anyway and let's talk. <p style="border:0px solid rgb(229,231,235);font-family:'Titillium Web', sans-serif, Inter, Arial, Helvetica, sans-serif;margin:0pt 0px;color:rgb(66,66,66);font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);line-height:1.38;">Looking forward to meeting you,<p style="border:0px solid rgb(229,231,235);font-family:'Titillium Web', sans-serif, Inter, Arial, Helvetica, sans-serif;margin:0pt 0px;color:rgb(66,66,66);font-size:14px;font-style:normal;font-weight:400;text-transform:none;background-color:rgb(255,255,255);line-height:1.38;">Willi
