TRAPDOOR Labs is looking for a talented and motivated Software Engineer to join our growing team.

You will work on developing secure, high-performance software solutions, contributing to innovative projects in the cybersecurity space. While this role may involve taking the lead on certain tasks or mentoring others, the primary focus will be on hands-on development, problem-solving, and applied research.

Key Responsibilities:

  • Design and develop exciting new software projects.
  • Work closely with the team to deliver high-quality solutions.
  • Collaborate with customers and internal stakeholders to understand requirements and deliver to their needs.
  • Contribute to applied research initiatives to improve and evolve our cybersecurity capabilities.
  • Support and share knowledge with peers, occasionally guiding junior team members.

About You:

  • You have solid experience in software engineering, with a strong understanding of secure coding principles.
  • Comfortable working with low-level desktop development for Windows and Linux.
  • Skilled in languages such as C, C++, C#, Python, and VueJS, and willing to learn new tools and technologies as projects demand.
  • Enjoys digging into challenging problems, exploring new ideas, and learning through applied research.
  • Able to take initiative and work independently while collaborating effectively within a small, close-knit team.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
