Role Description

In this role, you will lead the improvement of performance, reliability, and implementation quality of the CPU microarchitecture used across Signaloid's products. You will:

  • Be responsible for improving the instruction set architecture of Signaloid's processor platforms.
  • Be responsible for improving the tools for functional emulation of the microarchitecture of Signaloid's processor platforms.
  • Be responsible for coordinating with the RTL Implementation Lead and Compiler Tools Implementation Lead to achieve company-wide objectives and key results related to performance, reliability, and implementation quality of Signaloid's processors and computing platforms.
  • Coordinate with the Compiler Tools Lead to deliver support for new programming languages and runtime systems on top of Signaloid's processor platforms.

After a year in this role, based on your demonstrated performance, you will have the opportunity to:

  • Lead new architectural design work across Signaloid's compute architectures.
  • Lead the implementation of your own architectural ideas in collaboration with a larger team.
  • Contribute to the strategic direction of Signaloid's computing platforms.
  • Expand your role to encompass other areas in which you have demonstrated exceptional competence.
  • Thorough understanding of architectural and microarchitectural concepts of modern computing systems.
  • Good understanding of the required steps from source code compilation to binary execution in modern computing systems.
  • Three or more years experience writing low-level C/C++.
  • Experience developing C/C++ software for deployment in commercial products.
  • An ability to communicate complex engineering ideas succinctly and clearly.
  • Honesty, empathy, and a willingness to see the world from the viewpoint of others.

Additional Desirable Attributes, Skills, and Experience:

  • Familiarity with Python, Rust, and Go.
  • Familiarity with cross-compilation toolchains, LLVM, and RISC-V architecture.
  • Good understanding of digital arithmetic and number formats used in modern computing systems.
  • Applied mathematics background (with good working knowledge of probability theory, statistics, Bayesian methods).
  • Background in the role of uncertainty in measurements and in engineered systems.

Our Recruiting Procedure

  • All positions require you to write a one-page cover letter (you can also substitute the cover letter for a snippet of code that will run on the platform; be creative!). We use the cover letter / code snippet to screen for communication skills, as clear communication is essential in a remote working environment.
  • Applicants who pass the cover letter screening receive an initial 15-minute Zoom screening call with a member of our People Development Team to discuss your CV.
  • Applicants who pass the screening interview, regardless of the position they are interviewing for, will be given a real-world project to solve over the course of one week (or two weeks if you are currently employed in a full-time job). In exchange for your time, we give you two books relevant to the rest of the interview process.
  • Applicants who successfully complete the project are invited for an interview with people from our core teams which will use the project you completed as a discussion point.
  • In the final stage, applicants are invited for an on-site interview with members of the team in Cambridge, or a "virtual onsite" interview where a team from Signaloid will be at your disposal to implement a solution to a representative challenge you could face in the role.

A flexible remote-first work environment

  • Be part of an international team with the flexibility to choose where you live, as long as you are available to be online during the hours 09:00 to 17:00 UK.
  • Regularly join the rest of the team for in-person sessions somewhere in Europe (travel and lodging expenses covered by Signaloid).

Competitive compensation

  • Yearly bonus based on company's Objectives and Key Results (OKR) performance and bi-yearly bonus based on your project team's OKR performance.
  • Simple transparent compensation across the company.
  • All full-time employees receive attractive stock options package.

A driven but respectful environment

  • We never speak ill of others even if we differ in our viewpoints; we show up every day with a sense of urgency; we treat each other with respect as though each day were our last.
  • No isolated "projects": No person in the team works in isolation and a successful outcome for the thread of work you lead will inherently depend on getting help from (and helping) other members of the team.
