Senior SecOps Engineer

What we do and why we're looking for you

Despite the name, we’re not a bank. We’re building productivity tools for small businesses and accountants. Our founders claim we’re one of the fastest growing startups in Europe and looking at the stats we believe them.

We're proud of the way we work and of our values – we care deeply about quality and sane development practices. We also strive for simplicity and pragmatism.

Architecture & Stack

Our systems are mostly done using Ruby on Rails. We use Python for machine learning. We have a large web app, a few smaller ones, a few mobile apps (Android and iOS), a growing fleet of services (in the sense of Service-Oriented Architecture) talking via HTTP and backed by a bunch of PostgreSQL databases. All of this runs on AWS.

Team, Challenges & You

The development team is mostly in Bulgaria. Because we’re a remote company we have people in Sofia, Plovdiv, Burgas, Varna, Ruse. Everyone can choose where to work from. However, if you need to socialize in a face-to-face manner - we have a nice, spacious office in the centre of Sofia (near National Palace of Culture).

We have reasonable processes, organised Kanban boards, stand-ups that don’t last more than 10 minutes and product owners writing detailed (sometimes a bit too detailed) specifications. We value highly the quality of the code and good practices. We’ve suffered enough without them. Our management is well aware of that. We’ve even had the need to explain that we don’t need so much time for paying back technical debt. Some of us even talk about those things (code reviews, automated testing, refactoring).

What do we seek
Our ideal candidate is someone who shares our love of quality and doing things the right way. Perform a number of functions including architecting, developing and fielding secure network solutions to protect against advanced persistent threats, developing/engineering trusted systems into secure systems, and managing security technology will be one of the many things you'll have to tackle on daily basis. Overall with your help we'll plan and carry out security measures to monitor and protect sensitive data and systems from infiltration and cyber-attacks. We're looking for good and experienced engineers, who are not afraid to learn new things and work on hard problems. If this sounds interesting and you think we might "click", get in touch with us.

What You'll Do:

  • Provide architectural mentorship for securing our AWS environments, Kubernetes clusters and the systems running within them;
  • Perform security design reviews for infrastructure-related projects;
  • Document and communicate security configuration and hardening guidelines for infrastructure components;
  • Craft automated security auditing and monitoring software and infrastructure related to the above;
  • Administer security-related infrastructure and applications;
  • Help increase the security of all of our applications and services by communicating with the Product team and the wider Engineering team to help make changes to apps to make them more secure;
  • Organize internal and external penetration testing.
  • Be responsible for answering security questionnaires from our vendors or potential investors.

What You Bring:

  • You possess a deep understanding and recent experience with Linux system administration and hardening experience
  • You are proficient in scripting languages, such as Python, Bash, Ruby or Golang
  • You have knowledge of cryptography including x.509 certificates, encryption algorithms, and their practical applications
  • You have experience performing threat modeling for systems and infrastructure to identify potential security issues
