Join bloop if you're passionate about using AI to solve complex software engineering challenges and want to be part of a team that's working to transform how developers interact with and modernize legacy code bases.

Software Engineer position focusing on Rust and AI at bloop, a company modernizing legacy code

Software Engineer (Rust, AI)

# Tl;dr

We're combining LLMs and transpilers to translate COBOL into Java. If you're proficient in Rust, are interested in static analysis, and have a strong product mindset, this role could be a great fit. Come and build LLM pipelines and agents, that help the largest companies modernise their legacy codebases.

# Background

All large companies are stuck with legacy code running critical systems, written in languages that are dying and running on architectures that are increasingly expensive to maintain.

Our code translation pipeline automates the menial task of converting code from one language to another.

Previously human engineers would have had to read the legacy code and translate the codebase by hand, file by file, into the target language.

We're pioneering a novel approach to this problem, and leveraging LLMs to produce readable code in a fraction of the time.

# What's the role?

AI Agents are currently the bleeding edge of applied AI research, and you may have seen projects like Devin, OpenDevin, SWE-Agent, or GitHub Copilot Workspace.

This role is to build an AI Agent to perform refactoring of the transpiled code, that could only be possible with an LLM.

You'll collaborate with a small, talent-dense team of AI Engineers and Compiler Engineers to design and implement the AI Agent.

You'll love what we're working on if you're interested in:

- LLM Agents
- New LLM models and architectures
- Programming languages and compilers

You'll be joining a small group of engineers who are obsessed with the challenges posed by code translation, and who want to build tools to improve the process of writing and maintaining software.

# Key requirements

- Proficiency in Rust (professional experience preferred)
- Hands on experience building with LLMs
- Strong fundamental understanding of LLM pipelines and agents

Also nice to have (bonus points)

- Experience evaluating LLM pipelines
- Understanding of programming language design

# Benefits and Perks

- Up to ~0.5% options
- Competitive salary
- 25 days holiday, in addition to bank holidays
- Top tier private medical insurance

Product Engineer (Rust, AI)

# Tl;dr

Core Rust engineering role at a startup backed by Y Combinator and leading VCs, building tools that directly help software engineers.

# Background

bloop's automatic code translation solution automates the menial task of moving code between a source and target language. Traditional approaches to this problem result in code that is unreadable, and the alternative of rewriting a system from scratch is unfeasibly expensive for many projects. We're pioneering a novel approach to this age-old problem, building on our expertise in solving coding problems with LLMs.

# What's the role?

We're automating code translation between two programming languages. To do this we're developing pipelines that utilise source to source compilers and LLMs that can scale to support massive amounts of code. 

You'll work at the heart of this, collaborating with a small, talented team to design and implement the core engine that powers the pipeline. You'll work on the forefront of compilers, automated testing, LLMs (training and local inference) and static analysis.
