About the role

We are hiring a Principal Engineer to own the hardest technical problems in our product and see them through from first sketch to stable production. You will set technical direction, design systems that scale, and raise the engineering bar through your own work and the people around you. This is a hands-on leadership role: you write code, review designs, and ship.

What will you do?

You will own outcomes, not just tasks. Expect to spend your time on the following.

• Own projects end to end. Take an ambiguous problem, shape the requirements, design the solution, break down the work, deliver it to production, and stay accountable for how it runs afterwards.

• Lead system design. Author and review architecture for services, data pipelines and integrations, with clear trade-offs on scale, latency, cost, consistency and reliability.

• Write and review critical code. Build the hardest components yourself, and set standards for code quality, testing and maintainability through code and design reviews.

• Own deployment and operations. Design CI/CD, infrastructure and release strategies. Drive observability, on-call readiness, incident response and post-incident learning.

• Solve hard problems. Debug production issues across the stack, and find root causes in performance, concurrency, data and scaling problems.

• Mentor and multiply. Coach senior and junior engineers, grow future tech leads, and make the whole team faster and more confident.

• Partner across functions. Work with product, design, data and business teams to turn goals into technical plans, and to say no or reshape scope when needed.

• Shape technical strategy. Guide build-versus-buy decisions, manage tech debt, evaluate new technologies, and contribute to the engineering roadmap.

• Raise the bar. Help define engineering practices, hiring standards and culture, and take part in interviewing.

What are we looking for?

• Bachelor's degree in Computer Science or a related field, or equivalent practical experience.

Core engineering

• 10+ years of professional software engineering, with a track record of shipping and running production systems.

• Strong computer science fundamentals: data structures, algorithms and complexity, operating systems, networking, databases and concurrency.

• Fluency in at least one major backend language (for example Python, Go, Java, or Node.js/ TypeScript) and the ability to pick up others quickly.

• Deep knowledge of relational and NoSQL data stores: schema design, indexing, transactions, query tuning and replication.

System design and problem solving

• Proven ability to design distributed systems that are scalable, fault tolerant and cost aware, and to explain the trade-offs clearly.

• Experience with APIs, event-driven and asynchronous architectures, queues, caching and service-to-service communication.

• A structured approach to ambiguous problems: break them down, test assumptions, decide with incomplete data, and measure results.

• Strong debugging instincts, including performance profiling and production troubleshooting.

Delivery and operations

• Have led at least two significant projects from inception to production, including planning, milestones, risk management and launch.

• Hands-on experience with deployment: CI/CD pipelines, containers (Docker, Kubernetes), a major cloud (AWS, GCP or Azure), and infrastructure as code.

• Practical experience with monitoring, logging, alerting, SLOs and incident management.

• Habit of writing tests and automation, and of leaving systems more reliable than you found them.

Leadership and communication

• Experience leading engineers without formal authority, through influence, mentoring and clear technical writing.

• Excellent written and verbal communication: design docs, RFCs and concise updates to non-technical stakeholders.

• Ownership mindset, sound judgment on priorities, and comfort working in a fast-moving environment.

Nice to have

• Experience in fintech, lending or another regulated, data-heavy domain.

• Exposure to AI/ML or LLM-based systems in production: model serving, evaluation, retrieval, and cost and latency management.

• Deep experience with data engineering: streaming, batch pipelines, warehouses or search systems.

• Security and compliance awareness: authentication, encryption, audit trails, secure SDLC.

• Experience with multi-tenant SaaS, high-throughput systems or zero downtime migrations.

• Open-source contributions, conference talks, or technical writing.

• Experience scaling an engineering team or helping set up hiring and onboarding practices.

• Grafana monitoring and dashboards

Responsibilities:

• Handle production incidents, troubleshooting, and root cause analysis.

• Collaborate with teams to improve system reliability and availability.

This is a chance to get in early on something that's scaling fast, and to get years of experience compressed into months because of it. Instead of managing a slice of an established machine, you'll be sitting across from senior engineering leaders as a peer, designing the drills that decide whether a team holds together the day it actually matters, and watching people get visibly better at their jobs because of something you built. That kind of exposure and ownership doesn't exist at a big firm where you're twenty layers from the outcome. Here, what you do this month changes what the company looks like the next, and you'll build in a year the judgment it takes most people a decade to earn.

The role

We're hiring a Customer Success Engineer to be the backbone of our customer relationships. You'll work directly with customers, using our innovative platform to teach them to become elite, world class incident responders.

This is a role built around seeing people get better every day. You'll be part of a brand new, innovative method of teaching incident response skills, and you'll help people so that when an incident actually happens, they don't panic. They stay effective and make a meaningful impact, both for themselves and for their organisation. You'll also have a direct line into shaping and improving the product itself through what you see and learn in the field.

What you'll do

• Work hands on with customers running simulations, coaching and teaching them so their teams get better at incident response. Being a great coach is non negotiable here, and we want people who genuinely enjoy helping others improve.
• Take full ownership of customer outcomes. Proactively spot risk, gaps and opportunities rather than waiting to be asked, and drive them to resolution without needing to be chased.
• Partner with product to design and refine drill simulations, working closely with customers to get feedback and make sure every simulation is genuinely impactful.
• Work at startup pace. Partner cross functionally with sales, product and engineering, feed customer insight back into the roadmap, and help us grow rapidly as a company.
• Be comfortable learning resiliency engineering, cognitive systems design and other best practices as we develop them, and bring that learning back into how we teach and build.

What you'll bring

• 4+ years of hands on incident response experience as an SRE, on call engineer or first responder. You've been paged at 3am, run an incident bridge and written the postmortem. This isn't theoretical.
• Exceptional communication range. Equally comfortable presenting incident maturity findings to a senior exec and getting into the technical weeds with a mid level engineer. You adjust altitude naturally without dumbing anything down.
• A genuine growth mindset. You're excited to learn resiliency engineering and cognitive systems design style thinking, and you want to get hands on building better drills and incidents, even if you haven't done it before.
• Extreme ownership. You don't wait for instructions. You spot the problem, take the initiative and see it through.
• Genuine excitement to work at a fast growing startup. Comfortable with ambiguity, shifting priorities and wearing multiple hats as we scale.

What would make you stand out

• You enjoy teaching and sharing knowledge, whether that's pairing with someone, onboarding new colleagues or something entirely outside of work.
• You can clearly communicate your own on call experience, including the pain that comes with it.
• You care about impact. It's not just about doing the job well, it's about whether what you did actually moved the dial for the customer.
