About SIMBA Voice Agents by Speechify
SIMBA lets companies deploy natural, human-sounding AI voice agents in 71+ languages with sub-second latency. We don't just hand customers a product and wish them luck — every customer gets a Forward Deployed Engineer who builds their agents, joins their Slack, and iterates with them weekly. We're building the future of voice AI, and we're looking for someone who can sell that vision and help bring it to life.
