Senior Python Engineer, Turing

Miami Shores, FL, United States

Job Description Role Overview:

This position is within a project with one of the foundational LLM companies. The goal is to assist these foundational LLM companies in enhancing their Large Language Models.

One way we help these companies improve their models is by providing them with high-quality proprietary data. This data serves two main purposes: first, as a basis for fine-tuning their models, and second, as an evaluation set to benchmark the performance of their models or competitor models.

For example, for SFT data generation, you might have to put together or be provided a prompt which contains provided code and questions, you will then provide the model responses, and write corresponding Python code to solve the questions.

For RLHF data generation, you may need to create a prompt yourself or use one provided by the customer, ask the model questions, and evaluate the outputs generated by two versions of the LLM. You'll compare these outputs and provide feedback, which is then used to fine-tune the models. Please note that this role does not involve building or fine-tuning LLMs.

What does day-to-day look like:

Design, develop, and maintain efficient, high-quality Python code to train and optimize AI models.
Conduct evaluations (Evals) to benchmark model performance and analyze results for continuous improvement.
Familiarity with Python frameworks and libraries
Evaluate and rank AI model responses to user queries across diverse domains, ensuring alignment with predefined criteria.
Develop comprehensive explanations and rationales for evaluations, showcasing excellent reasoning and technical expertise.
Lead efforts in Supervised Fine-Tuning (SFT), including creating and maintaining high-quality, task-specific datasets.
Collaborate with researchers and annotators to execute Reinforcement Learning with Human * Feedback (RLHF) and refine reward models.
Design innovative evaluation strategies and processes to improve the model's alignment with user needs and ethical guidelines.
Create and refine optimal responses to improve AI performance, emphasizing clarity, relevance, and technical accuracy.
Conduct thorough peer reviews of code and documentation, providing constructive feedback and identifying areas for improvement.
Collaborate with cross-functional teams to improve model performance and contribute to product enhancements.
Continuously explore and integrate new tools, techniques, and methodologies to enhance AI training processes.

Requirements:

3+ years of strong experience with Python programming language.
Industry experience and knowledge of code quality, formatting, and best practices of software development
Experience with Python’s testing ecosystem, including unit, integration, and property-based testing.
Knowledge of multi-threading and asynchronous programming in Python.
Ability to work with architectural patterns and refactor code without introducing regressions.
Strong debugging skills, including fixing memory and concurrency issues.
Fluent in conversational and written English communication skills

We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions.

A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance.

If you match these requirements and wish your job involved more variety and less bureaucracy, let's talk: info@fusionbox.com.

5 years of using Python pythonically
3 years of React Experience
Django Experience Preferred
US-Based
Must be able to communicate complex technical concepts clearly and professionally in spoken English.

Full-Stack Engineer, AIDAR

Hamburg, Germany

## Remote-friendly within Germany

You'll join as our full-stack developer, working directly with Janek across backend systems, frontend, and data pipelines, and with Caspar on product strategy and design as features take shape. The product is live and running, and it's time to scale it, evolve it, and make it sing. This is early in the startup's journey: no hierarchies between you and the founders, fast communication instead of layers of approval, and priorities that shift quickly as the product and the market do. We communicate directly and expect the same in return, always with respect. Work when you work best, whatever hours suit you, as long as the output holds up; we care about getting things right, not about being seen at a desk. We aim to be a responsible company to work for, and the responsibility you get in return grows as the team grows.

Experience with Flutter, or solid frontend experience combined with a strong willingness to learn Flutter
Comfortable working with large databases and complex datasets
Based in Germany is a must
Able to take ownership of open-ended problems: analyze the situation, evaluate different approaches, and ship the best solution. This role is about solving problems, not implementing perfectly specified requirements
Interested in thinking beyond individual tasks. We're looking for someone who wants to understand the bigger picture, from our users' daily challenges to how every technical decision contributes to the product
Hands-on experience with AI/ML (LLM agents, embeddings, recommendation systems, etc.) is a plus, but not required
Comfortable using AI-assisted coding tools to increase productivity while maintaining a robust, sustainable codebase
Enjoys working closely with a two-person founding team, with direct feedback, shared decisions, and no layers between you and what gets built
