Senior AI Software Engineer

Written by Rebel Recruiters on .

Role: Senior AI Software Engineer – TypeScript

Location: Nottingham City Centre, hybrid- twice /week in the office.

Salary: Up to £75k plus benefits, stock options

Have you been waiting for a new tech start-up to come to Nottingham with all their greenfield work, cool shiny tech, and infinite potential to make you filthy rich as one of their first hires?

Well, look no further: they’ve arrived!

Looking for what will be their 4th dev (including a hands-on co-founder) you are a senior TypeScript Software Engineer who absolutely loves AI, with big aspirations. You live and breathe your craft: not satiated with your 9-5, you love tinkering with new and emerging tech in your free time and have come to have quite an affection for OpenAI, LLMs, and AI in general, and have been fortunate enough to get to play with it in your job, too- Langchain is a particular favourite!

You know you’re a great engineer but feel your talents might be being wasted in your current role, where you’re siloed and don’t get to flex your creative development muscles anywhere near as much as you’d like…that is not the case here.

This is a true tech company- the tech is the business, so you’ll never be an afterthought: without you and your fellow software builders, the company can’t exist!

You’ll be treated as a founding member of the team, will have a big say in technical direction, will help build up the team, and be getting your hands dirty with lots of shiny, greenfield development-what’s not to love?!

This is a hybrid role, so you’ll be going into the office twice per week. It’ll be a great time to have social interactions with your team, share ideas, and feel the buzz of what you’re all creating!

At a glance, you’ll be great with:

  • Proficiency in Langchain JS, LangGraph JS, Typescript
  • Demonstrable experience building Multi Agent AI Systems
  • Hands-on experience with major LLM providers such as OpenAI
  • Experience in designing and implementing web applications
  • Strong understanding of AI ethics and data privacy principles
  • Knowledge of best practices in secure software development
  • Front-End Development and CSS skills

If you’ve got any experience with the following- commercial or personal- it would be very useful:

  • Experience with Svelte Kit, Supabase, and Postgres
  • Familiarity with Effect TS
  • Knowledge of cloud platforms (AWS / Azure / Google Cloud)
  • Understanding of basic information security principles
  • Awareness of GDPR and its implications for AI and data handling (preferred)

If this sounds like the role you’ve been waiting for, apply now or drop me a line to find out more!

We welcome diverse applicants and are dedicated to treating all applicants with dignity and respect, regardless of background.

Salary: Up to £75K + 12% pension, life insurance and more.

Are you someone who loves our planet and wants to do good in a role with a biodiversity-focused global organisation?

Would you like to do more with your technical skills? Are you somebody who’s dreamed of working to support and connect people and systems for the benefit of species conservation? Read on.

Thankfully, as you read this there are organisations already working on deeply detailed and technical systems aimed at recovering and regenerating ecosystems. These are essential in promoting collaboration and preventing biodiversity loss or limiting loss in scenarios where it is unavoidable. These systems range from databases on endangered species and key biodiversity areas to things like tracking pollution, monitoring species and the recovery of regions or sites. They are integrated into companies, governments and organisations all over the world and help all to understand how ecosystems interact and influence one another and how we, as humans, can protect them.

A passion for nature or the environment more broadly will serve you well here, as a conservation org. they are hyper-focused on impact and making their work accessible, integrating partners and customers into their platform to expand who is making use of this data for decision-making.

The CIO here has real ambitions to see the tech evolve across this 2,000+ people org with ~10 regional offices and teams spread more broadly than that across biodiversity hotspots (physical & political). That includes hardware, software, data science, and the whole shebang.

So, what will you be doing specifically?

Designing, building and maintaining the tech foundation that underpins a key database and platform. This will include investigating issues and implementing fixes to build in resilience and remove points of failure. You’ll also bring documentation up to standard; much was completed by consultants and wasn’t always updated by internal members of the team so there is some work to do in enabling the evolution of this platform and this may include switching to Python and Django or other technologies in the longer-term – 2+ years.

The skills priorities are Ruby on Rails and exp building APIs, exp with geospatial data and GIS tools is highly desirable. The role will be 70:30 Backend : Leadership, with some infrastructure and security tasks in there.

There are a number of partners who collaborate on various other interlinked tools, so cross-team collaboration experience will be beneficial. If you’ve touched on security or some DevOps tools and cloud technologies, but not extensively, there is support to grow your knowledge in the form of partners/teammates and funding for courses, textbooks or other materials if needed.

Experience Required:

  • Ruby on Rails – Backend focused
  • PostgreSQL
  • Docker
  • DevOps – AWS
  • Leadership Experience

It’s a small team of 5, including the systems manager, that is part of a broader conservation tech ecosystem of 5 to 6 other teams and systems that occasionally collaborate or share resources, including with some of those partner orgs.

You’ll be involved with the design, review code and work closely with, scientists, ecologists, and climate researchers, prioritise work and engage some stakeholders or 3rd parties, as some internal teams such as GIS and data analysts and program managers to support them in delivering projects across various tiers of the conservation sector.

Interested in addressing biodiversity loss and turning things around? Do say hello 😊.
