Job summary

Meta’s Applied AI (AAI) team within Multimedia & Multimodality seeks a Software Engineer to own data and evaluation pipelines across image, video, audio, and speech modalities. You will design scalable pipelines and evaluation metrics, and mentor engineers to raise the bar on quality and impact.

You will contribute to state-of-the-art multimodal research and production systems, building agentic workflows, data provenance, and robust evaluation harnesses for real-world deployments.

Qualifications

• 3+ years building ML systems in production or research.
• Strong Python and PyTorch.
• Experience with speech, audio, or music ML - ASR, TTS, codecs, music information retrieval, self-supervised audio representation learning, or audio generative modeling
• Experience with large-scale data pipelines and distributed training
• Track record of translating research ideas into working, measurable systems

Responsibilities

• Design and build agentic workflows and pipelines, including human-in-the-loop and expert-in-the-loop designs, to automate data production and scale output past what manual authoring supports.
• Design and own data pipelines at scale: ingestion, filtering, pseudo-labeling and captioning with attribute classifiers, and provenance tracking for audio corpora.
• Build evaluation infrastructure: objective metrics (speaker/style similarity, codec and generator quality), human listening-test pipelines, and the correlation analysis that ties the two together.
• Improve training efficiency and reliability — distributed training, GPU utilization, codec and tokenizer retraining, experiment management.
• Reproduce and extend state-of-the-art research: implement new methods from papers into our codebases and run rigorous ablations.
• Mentor engineers on the team, contribute to hiring and onboarding, and raise the bar on evaluation and quality practice.
• Build and train generative and representation models for speech, sound, and music — including text-, audio-, and video-conditioned generation, infilling, editing, and style transfer.

Job description

Summary:

Applied AI (AAI) is Meta’s organization focused on making our AI models best-in-class, starting with coding. Within AAI, the Multimedia & MultiModality team covers the multimedia domain across every modality, on both the input and the output side of a model: image, video, audio, speech and music. We work directly with research, model-training and engineering partners across MSL, TBD and FAIR. Current problems include evaluating video experiences, diagnosing multimedia model behavior, producing domain-expert agent tasks, and building the data and measurement pipelines multimodal capabilities are trained and judged against.

About the role

You will take a modality or a capability area, decide what data is worth producing and how it should be measured, and carry it from an open question through to a pipeline that runs and a measurement the org relies on. This is a multimodal role, not a text-only role. You will work across image, video, audio and speech, as model inputs and as model outputs, and the data and evaluations you own will cover media, not text alone. You will choose where the pod invests, own outcomes beyond your individual contribution, set standards other engineers build against, and raise quality without becoming the review bottleneck.

Required Skills:

Software Engineer, Multimedia & Multimodal AI Responsibilities:

1. Design and build agentic workflows and pipelines, including human-in-the-loop and expert-in-the-loop designs, to automate data production and scale output past what manual authoring supports.

2. Design and own data pipelines at scale: ingestion, filtering, pseudo-labeling and captioning with attribute classifiers, and provenance tracking for audio corpora.

3. Build evaluation infrastructure: objective metrics (speaker/style similarity, codec and generator quality), human listening-test pipelines, and the correlation analysis that ties the two together.

4. Improve training efficiency and reliability — distributed training, GPU utilization, codec and tokenizer retraining, experiment management.

5. Reproduce and extend state-of-the-art research: implement new methods from papers into our codebases and run rigorous ablations.

6. Mentor engineers on the team, contribute to hiring and onboarding, and raise the bar on evaluation and quality practice.

7. Build and train generative and representation models for speech, sound, and music — including text-, audio-, and video-conditioned generation, infilling, editing, and style transfer.

Minimum Qualifications:

1. 3+ years building ML systems in production or research settings

2. strong Python and PyTorch

3. Demonstrated experience with speech, audio, or music ML - ASR, TTS, audio codecs, music information retrieval, self-supervised audio representation learning, or audio generative modeling

4. Experience with large-scale data pipelines and distributed training

5. Track record of translating research ideas into working, measurable systems

Preferred Qualifications:

1. Publications at top venues (ICASSP, Interspeech, ISMIR, NeurIPS, ICML, ICLR) in speech, audio, or music

2. Generative modeling of continuous data (diffusion / flow matching, audio or vision), and demonstrated ability to switch domains and ramp quickly

3. Audio DSP depth — pitch detection, FFT, real-time signal processing

4. Experience with disentangled or controllable generation (voice, emotion, style, instrumentation)

5. Experience building evaluation harnesses and human-eval pipelines for generative audio

6. Music domain expertise: stem separation, mixing, lyrics/vocal conditioning

7. Experience designing benchmarks or evaluations for model capability, with attention to grading reliability, reproducibility and label quality

8. Experience building data pipelines for image, video, audio, speech or complex media formats, including versioning, lineage and provenance

9. Experience designing AI agents, orchestration, or human-in-the-loop systems

10. Hands‑on experience evaluating or red‑teaming multimodal models, or creating the data used to improve them

11. Understanding of Responsible AI practices and building quality controls into AI output

12. Experience with zero-to-one work: forming a charter and standing up process while priorities are still moving

13. Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)

14. Experience with zero-to-one work: forming a charter and standing up process while priorities are still moving

15. Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)

16. Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
