Rime builds voice AI for enterprises running customer experiences at scale. Our text-to-speech models are purpose-built for high-volume conversational deployments, engineered for the pronunciation accuracy, latency, and deployment flexibility that production environments actually demand.
We started from a different premise than the rest of the field: voice AI isn't bottlenecked by model architecture. It's bottlenecked by data. So before we trained a single model, we built our own corpus: full-duplex, studio-quality conversational speech, recorded and annotated by PhD linguists. That's our moat. It's also why enterprises pick Rime when pilots need to convert into production.
We're backed by top-tier investors including Unusual Ventures, and we've built a team at the intersection of product, research, and craft. Building voice models is an art. We intend to master it.
We're hiring a Machine Learning Scientist to push the frontier of speech synthesis and speech understanding at Rime.
What You'll Own
Design, train, and evaluate speech synthesis models, autoregressive and non-autoregressive.
Drive research on full-duplex and half-duplex multi-modal architectures, including unified S2S systems.
Choose and iterate on speech representations: neural codecs, semantic tokens, mel features, continuous latents.
Build rigorous evaluation, objective and perceptual. Hold the bar on quality and prosodic control.
Collaborate with our linguists on TTS frontend behavior so modeling and frontend choices reinforce each other.
Deep familiarity with the speech synthesis literature, contemporary and historical — Tacotron, FastSpeech, VITS, VALL-E, the codec-LM lineage. Opinions on what worked and why.
Hands-on training with neural codecs (EnCodec, DAC, Mimi, etc.) and multiple representation choices.
Experience with full- or half-duplex multi-modal modeling (Moshi, LLaMA-Omni, streaming S2S).
Strong attention to detail on data quality. You notice when an annotation pipeline is silently degrading or when an eval set has leakage.
Willing to roll up your sleeves on unglamorous data and training work — paired with the agency to build pipelines so the team isn't stuck doing it by hand.
Working knowledge of TTS frontend (G2P, normalization, prosody) and experience working with linguists.
Strong PyTorch fundamentals. Comfortable with training loops, distributed training, model internals.
PhD or equivalent research experience in speech, audio, ML, or computational linguistics or a track record that makes the credential irrelevant.
Nice to have
Multilingual TTS experience.
Background in prosody or paralinguistics.
Published work in speech, audio, or core ML venues.
Experience taking research models to production: quantization, distillation, streaming inference.
Category-defining voice AI infrastructure, not incremental research deltas.
Direct collaboration with founders, including a CEO with a Stanford computational linguistics PhD.
Real impact on company trajectory.
Meaningful equity upside.
High ownership, high standards, low bureaucracy.
What We Offer
Competitive base + meaningful early-stage equity
Remote-friendly
Visa sponsorship available
Access to a proprietary, full-duplex, studio-quality conversational speech corpus
Compute and tooling to do the work
Direct influence on the future of voice AI
At Rime, we...
Are outliers
Cut through the hype to focus on the craft
Move fast with agency and freedom
Maintain a growth mindset, finding joy in the struggle
Do the right things, knowing that it'll lead to making money
If that sounds like you too, you'll be a great fit for Rime!

Our revenue team has a unique mission to help customers understand the deep impact that highly capable AI voice models can bring to their business and users. This Founding Account Executive role is a mixture of technical understanding, vision, partnership, and value-driven strategy.
You’ll be a key driver of opportunities through the entire sales cycle, from prospecting and deal execution to long-term account growth. You’ll work with researchers, engineers, and solution strategists to help customers evolve their industry with AI.
This role is ideal for someone who thrives in early-stage environments, loves building from zero, and is excited to help define how Rime’s voice AI technology is deployed across industries.
Own the full sales cycle — from cold outbound to signed contract. You find your way to the right buyers, earn their trust, and close.
Generate your own pipeline. You're a hunter who builds from zero — outbound, events, partner channels, whatever works.
Become a product expert. Run technical discovery, demo credibly to engineering and product teams, and translate capability into a clear business case.
Serve as a trusted advisor. Deeply understand your customers' priorities and help them deploy voice AI in ways that actually move their business forward.
Inform the roadmap. Synthesize market signals, customer feedback, and competitive intel — what you learn in the field shapes what we build.
Drive expansion. The initial contract is the floor. You build relationships that grow accounts over time.
A genuine hunter. You create your own pipeline, move deals forward with urgency, and don't wait to be told what to do next.
Technically fluent. You understand APIs, AI pipelines, and developer workflows — not as a talking point, but because you're genuinely curious.
Customer-obsessed. You care about outcomes, not just signatures, and you build relationships that last beyond the close.
Energized by hard problems. Bespoke deals, new verticals, and undefined playbooks don't intimidate you — they motivate you.
A sharp communicator. You write clearly, present with confidence, and adapt from a platform engineer to a C-suite exec.
Rime is an AI lab — you're not just selling software, you're working alongside the researchers and engineers building frontier voice models.
Voice AI is at an inflection point. The companies that win now will define the category — and you'll be one of the first commercial leaders helping shape that.
Direct exposure to how frontier AI gets built and deployed at scale, across some of the most demanding industries in the world.
Competitive compensation with meaningful equity and real performance upside — we want to build a small, high-performing team that has real ownership.

SF Bay Area (hybrid)
Salary range: $197,000 - $232,000
Reports to: VP of Marketing
About the role
Product marketing at Rime is not a support function, it's a core part of how we build and sell. We're looking for someone who's ready to own real scope: shaping how the market understands our products, sharpening what we build next, and producing the content that fuels our GTM engine.
You'll work closely with product owners, not downstream of them, bringing customer and market signals directly into roadmap conversations, and pushing back when priorities drift from what the market actually needs. At the same time, you'll be a prolific creator: fully focused on powering the pipeline, generating a steady stream of sharp, credible content that trains our sales team, fuels campaigns, and earns visibility in an AI-driven search and discourse landscape.
This is a hands-on, high-output role for someone who wants outsized ownership.
If you’ve had experience in fast-paced product marketing roles at developer platform, AI, or API companies, this could be the perfect role for you.
Represent the customer: Champion the needs and pain points of our customers through interview analysis, market research, competitive intelligence, and by engaging with analysts and our sales teams.
Own the story: Create positioning and messaging frameworks for our products, personas, and features by working closely with product and sales to understand needs and pain points. Develop persona specific messaging tailored for the needs of demand generation, SDR, sales, and channel partners.
Enable the team: Ensure everyone at the company understands our product and our customers in a way that is relevant to their jobs. Working with Product Management, produce sales collateral including playbooks, sales plays, pitch decks, case studies, competitive analysis etc.
Launch the product: Build and drive the strategy for launches by building plans and partnering with product management, demand generation, sales, and customer success.
Educate the market: Work with Demand Generation on a content strategy to support our pipeline goals; produce creative, compelling collateral (blogs, whitepapers, webpages, demos, videos, etc) and campaigns.
Bring your unique perspective: Develop and implement best practices and frameworks that improve outcomes for the company and the impact of product marketing.
View the written word and narrative as craft, not something to outsource to LLMs.
You’ve built (or helped build) product marketing as a function from scratch within a fast-paced startup environment
You know how to turn deeply technical capabilities into reasons a buyer actually cares.
Have strong product marketing experience for LLMs, AI agents, developer tools, APIs, or technical products.
Have a proven track record of owning launches end-to-end in a fast-paced environment.
Have experience working with and guiding senior partners to launch new products, features, and programs.
Excel at cross-functional collaboration.
Possess strong storytelling skills, with experience crafting compelling narratives that interrupt patterns and stand out from the crowd. You roll up your sleeves to write, record, and publish content yourself.
You have a strong product marketing background working on technical products that directly influence the growth of the company
You represent the voice-of-the-customer and can distill actionable product roadmap recommendations from customer feedback, market research, and competitive analysis.
Curious, sharp, energetic and a little relentless. You push on ideas, including your own. You want to win, and you want to win as a team.
