About the Engineering Hub
The Renaissance Philanthropy AI and Engineering Hub provides on-demand development technical assistance in support of grant-funded educational technology projects. Our support allows mission-driven teams to overcome hurdles and achieve their technical and impact goals.
Why Join Us?
We solve educational technology problems that require creativity, analytical rigor, and a deep understanding of emerging AI capabilities. Members of our team are trusted technical partners who help shape product strategy, architect novel solutions, and prototype new ideas from first principles. We move quickly, operate with a high degree of independence, and take pride in delivering reliable, thoughtfully-designed systems that make a meaningful difference.
This summer, we’re launching LEVI Literacy, with a goal of halving the number of struggling readers in the US within 5 years. We are seeking an expert in modern voice AI systems to support this work. The ideal candidate will be familiar with recent research advances, deeply understand the complexities of data-to-model pipelines, and have experience working with various speech or voice processing systems in production, including but not limited to automated speech recognition (ASR).
Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms spanning oral reading, spoken vocabulary tasks, and whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right, and fair, for every student. As part of the Engineering Hub, you'll bring deep speech technology expertise to complement our teams' strengths in learning science, product, and the classroom.
If you’re excited about applying modern speech AI technologies to address real-world learning challenges—and want the opportunity to experiment, innovate, and guide others—this is the place for you.
What You’ll Do
As a Research Engineer (Speech AI/ML) on our Engineering Hub, you will:
Technical Strategy & Consultation
Provide hands-on guidance to product and research teams, shaping technology roadmaps from model selection and fine-tuning strategy to deployment architecture.
Review architectures, prototypes, and designs for feasibility, quality, and maintainability — including streaming vs. batch, on-device vs. cloud, and latency, cost, and privacy tradeoffs.
Advise teams on adapting modern speech AI technologies — automatic speech recognition, foundation speech models, phoneme-level recognition and pronunciation assessment, speaker diarization, speaker identification, speech-plus-LLM pipelines — and on when off-the-shelf systems will and won't work for children's speech or naturalistic classroom environments.
Support technical hiring by helping teams identify both ML and domain-specific (speech) capabilities they need.
Prototype, Build, and Evaluate
Develop proof-of-concepts that explore new applications of AI and validate the viability of emerging approaches.
Fine-tune and adapt modern foundational speech models (e.g., Whisper,wav2vec2, HuBERT, WavLM) for children's speech, including phoneme-level recognition and pronunciation scoring against known reading targets.
Design and review end-to-end speech data pipelines — classroom audio collection, annotation workflows, and training/evaluation datasets — with student privacy built in from the start.
Develop proof-of-concepts that validate emerging approaches to recognizing, scoring, and analyzing children's speech in classroom conditions, and translate them into deployable, scalable features.
Lead evaluations beyond the standard word error rate metric: phoneme-level accuracy, robustness to classroom noise and overlapping speech, and fairness across dialects, accents, and English language learners.
Collaborate, Adapt, and Learn
Work directly with non-technical stakeholders to convert product needs into actionable technical requirements.
Build solutions that balance functionality, robustness, and the data collection needed for authentic impact measurement (e.g., A/B testing, RCTs).
Clearly communicate the limitations, risks, and failure modes of speech systems — where models underperform, for whom, and in what conditions — and when these can (or cannot) be mitigated.
Continuously expand your expertise as speech and language technologies evolve.
Education
PhD in Computer Science, Machine Learning, Electrical Engineering, or a related field preferred.
Candidates with a Master’s degree and strong practical experience will be considered. Publications in speech/NLP are a plus.
You may be a great match if you have:
Proven experience building and operating production-grade ASR or speech-processing technology systems.
Deep familiarity with modern speech processing system architectures and the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment.
Hands-on experience in one or more of: children's or atypical speech, pronunciation assessment, forced alignment, spoken-response verification, speaker diarization, or low-resource domain adaptation.
Working knowledge of the privacy and compliance considerations around voice data from minors (e.g., COPPA, FERPA) — or the judgment to develop it quickly.
A passion for educational technology, strong communication skills, and the ability to collaborate across disciplines.
Publications at top ML/speech conferences (NeurIPS, ICML, ACL, Interspeech, ICASSP)
Nice to have: familiarity with LLM-based analysis of transcribed speech; publications in speech or spoken language processing; experience building tools for students, teachers, or learning organizations.
Candidates with experience developing tools for students, teachers, or learning organizations are strongly encouraged to apply.
Outcomes
In 2-3 years, a successful Research Engineer will have assisted multiple product teams bring their education-focused, mission-driven ideas to life through technical guidance, hands-on development, and support for team capacity-building. Conditional on team needs, candidates will also have contributed to open-source projects and presented collaborative published work at conferences.
Values
You will thrive within our team, if you:
Have strong mission and vision alignment: You believe in the power of science, innovation, and technology to create a brighter future for all.
Exhibit high agency: You can move mountains and break perceived constraints.
Inspire others and are highly collaborative: You can motivate others to join your mission and goals. You understand the value of going further by working with others.
Value exceptional talent and the power of networks: You can spot or nurture exceptional talent and believe in the value of building networks and the power law of talent.
Are comfortable working in fast-moving and ambitious teams: You are not afraid of ambiguity and enjoy working at pace.
You are not afraid of ambiguity. You ask tons of questions. Intellectual curiosity is your default operating mode. You are comfortable working in fast-moving and ambitious environments.
You are as excited about being part of building Northwest Arkansas into a destination for entrepreneurs and young professionals as you are about deploying capital. You love building community.
Diversity
We encourage anyone who is interested in this role to apply, regardless of whether you feel you meet 100% of the qualifications. The top candidates will bring their own unique perspectives, experiences, and backgrounds from a variety of industries along with many but not necessarily all the skills listed above.
