<p><strong>Janea Systems (USA)</strong> is a dynamic team of the best & brightest software engineering specialists and solutions innovators, from around the world. From kernel to cloud, we provide high-impact software development services to Fortune 500 companies.<br> <strong><br></strong>This is a future opportunity role, not a live start. We evaluate strong freelance ML engineers ahead of client demand so that when a project matches your profile, we come to you with concrete scope, rate and start date — not with a three-week search. Being accepted into the pool is not a guarantee of work, and we will be direct with you about timing: it may be weeks or it may be months. In exchange, we keep our process short, we do not ask for unpaid work, and once you are in, you hear about relevant projects before we go to market.</p> <p><strong> </strong></p> <table width="585"> <tbody> <tr> <td width="130"> <p><strong>Basis</strong></p> </td> <td width="455"> <p>Independent contractor.
