AI Engineer - Model Post Training

Wider Security LLC Newport, RI 🇺🇸 Remote

Newport, RI

1mo ago Closed

$100 - $250/hr Part time Ai Engineer Ai Model Optimization Ai Model Training

This position is no longer accepting applications (closed Oct 18, 2026).

Job Description

Wider Security LLC is hiring a part-time, fully remote AI Engineer to focus on post-training and alignment for large language models at scale. The work centers on supervised fine-tuning and safety-focused evaluation, with hands-on experience needed to support model tuning from 7B through 70B and beyond.

This role is built for an async-first team and emphasizes measurable outcomes across training, calibration, and adversarial robustness. You will help lead end-to-end post-training workflows, from data preparation through evaluation and deployment-oriented integration.

What you’ll do

Lead and contribute to post-training workflows including supervised fine-tuning, instruction tuning, DPO, RLHF, RLAIF, and related alignment techniques
Use QLoRA and other efficient fine-tuning methods across models spanning 7B to 70B+ parameter ranges
Train models to produce reliable structured outputs under adversarial input conditions
Build and run evaluation pipelines for safety-critical behavior, including adversarial test suites, red-team integration (for example, Garak), and regression tracking across model versions
Calibrate decision thresholds to support tiered policy configurations, including logprob-based confidence calibration at the serving layer
Design training approaches that preserve inference-time policy specification, enabling behavior changes without retraining
Curate and prepare training data, evaluation sets, and preference data pipelines
Iterate on training strategy to improve task performance, calibration, and adversarial robustness
Document approaches and decisions clearly for a distributed, async-first team

What you’ll need

US citizenship and current residency in the United States (firm requirement)
Concrete, verifiable production experience post-training open-weight LLMs, with experience at 7-8B, 13-30B, or 30B+ scales welcomed, and larger-scale experience a plus
Experience with modern open-weight model families such as Llama, Qwen, Mistral, or similar
Hands-on experience with QLoRA, LoRA, and efficient fine-tuning methods for large models
Background in alignment approaches including SFT, DPO, RLHF, RLAIF, or constitutional AI approaches
Experience training models for reliable structured output (JSON, schema-constrained generation, function-call style outputs)
Familiarity with serving stacks such as vLLM, TGI, or similar, plus comfort working with logprob-level model outputs
Deep familiarity with distributed training frameworks including DeepSpeed, FSDP, Megatron-LM, or similar
Proficiency in Python and comfort with multi-GPU, multi-node training infrastructure
Ability to work independently and manage time effectively in a part-time, async-first environment

Technologies

Python, QLoRA, LoRA, SFT, DPO, RLHF, RLAIF
constitutional AI, vLLM, TGI, DeepSpeed, FSDP, Megatron-LM
Llama, Qwen, Mistral, Garak

Eligibility

Applicants must be US citizens currently residing in the United States. The company is unable to consider applicants outside the US or without US citizenship, regardless of work authorization status.

Strong preferences

Direct experience training safety classifiers, content moderation models, jailbreak or prompt injection detectors, or other trust-and-safety ML systems
Experience with adversarial evaluation frameworks such as Garak, promptfoo, or similar
Comfort with deployment constraints typical of regulated or restricted-network environments

Bonus qualifications

Published research or open-source contributions related to LLM training, alignment, or AI safety
Prior work at an AI lab, a foundation model team, or on a production safety classifier
Experience designing or operating tiered policy systems where model behavior can be modulated at inference time

Location: Newport, RI (remote)
Job type: part time
Pay: USD 100 - 250 per hour
