You will work closely with founders and customers in a fast-growing startup environment, focusing on high-quality software delivery and infrastructure as code. ## Job description Our product helps security teams quickly and accurately detect intrusions in their cloud environment using canaries - decoy tripwires deployed to deceive attackers. We're at a massive inflection point and this is a hugely exciting time to join the company: - We've just raised a $20m Series A https://tracebit.com/blog/series-a led by FirstMark with Accel, MMC, Tapestry and CCL. - We doubled ARR last quarter, work with companies like Riot Games, Docker and Snyk, and have grown from 5 people to 26 in 18 months. - Our research https://www.techradar.com/pro/security/google-gemini-security-flaw-could-have-let-anyone-access-systems-or-run-code recently helped fix a P1 security flaw in Google's Gemini CLI. We’re looking for someone who… - Cares deeply about producing high quality work and is ready to dig into the details but is savvy in making the correct tradeoffs on pace vs. quality. - Has spent at least a few years shipping software at some degree of scale and/or criticality. - Ideally at a Product focused company and/or working with at least 1 of the public clouds (AWS, Azure, GCP, etc.) - Is excited by the pace and rate of change that is inevitable in any successful, early stage startup. - Gets their energy from getting things done and in the hands of customers but is also here to have fun along the way! If you don’t fit this bill exactly but think you could make a difference here - please, apply! ## Role Reporting to Niall https://www.linkedin.com/in/niall-gallagher/, our Engineering Lead, and with significant exposure to our CTO and Co-Founder, Sam https://www.linkedin.com/in/sam-j-cox/, you’ll join a team of other awesome engineers looking to make their mark on the world. This includes: - Working face to face with both founders, the whole engineering team and our customers and prospects to build a delightful product that solves real problems. - Working across the stack, mostly in C# on .NET Core 10 (here's why https://tracebit.com/blog/why-tracebit-is-written-in-c-sharp), but also Terraform and building out our frontend in HTMX. - All the good practices you’d expect from technical co-founders who’ve done this before (CD, Infrastructure as code, simple but scalable and powerful architecture) - We’re a small, tight team with demanding customers so expect to be shipping every day with very little bureaucracy. - We actively encourage AI-assisted development and give every engineer full access to tools like Claude and Codex. - We’re based in a Central London office and work here 5 days a week (and everyone we hire will too). ## FAQS How is work organised at Tracebit? It’s a small, tight team - we have a standup everyday, each team member is usually responsible for delivering something reasonably large for customers and we meet every few weeks to talk about longer term plans. Between that - there’s a tonne of discussions, customer feedback and analysis, but not a huge amount of process, the team is trusted to prioritise where to spend their time. Where is the office? The whole team works together in an office right next to Warren Street tube station https://tfl.gov.uk/hub/stop/940gzzluwrr/warren-street-underground-station/ - there are lots of great places to grab lunch nearby. Are you doing hybrid/remote? ‍Short answer: No, but flexible on a day to day basis. Long answer: We are set on building the company on a foundation of an office based culture. We are a very early stage company and think that we’ll build the best company at the fastest pace we can whilst also having a lot of fun by physically working together 5 days a week. On a case by case basis (e.g. leaving early for a holiday, staying home for a builder, working remote for a few days to visit family, etc. etc.) we’re very reasonable and flexible. We respect that this is not for everyone. ‍What are the working hours like? ‍We think 9am-6pm will bring a great cadence to work. As a Founding Engineer there will definitely be times you need to pick up work outside of these hours, we’re keen to limit this where we can but also offer flexibility in return. Can you sponsor visas? We can support various types of working visas in the UK, including: - Skilled Worker Visa (both from within and outside the UK) - Intra-Company Transfer Visa - Graduate Visa Transition We are keen to support candidates who require visa sponsorship. Please let us know which specific visa type you might need during the initial application or interview process. Our team is committed to helping talented individuals navigate the necessary visa requirements. ## About Tracebit ## Company Overview - **One-liner**: Tracebit uses deception technology to detect attackers by deploying realistic canaries (decoy resources) across cloud environments, triggering high-confidence alerts the moment an attacker touches one. - **Entity Type**: Private (Series A) - **Headquarters**: London, England (86-90 Paul Street, London, EC2A 4NE) with an additional office in Manhattan, New York City - **Founded**: 2023 - **Founders**: Sam Cox (Co-founder & CEO) and Andy Smith (Co-founder, CTO) ## Core Business - **Primary industry**: Cybersecurity (cloud intrusion detection and deception technology) - **Target customers**: B2B – security teams in enterprises of all sizes - **Mission**: “Help companies detect and contain security incidents in minutes, not months” by flipping the detection problem on its head – instead of hunting for anomalies in billions of events, Tracebit deploys canaries that are themselves the anomalies. ## Products & Services - **Tracebit Platform**: A SaaS-based deception platform that automatically deploys realistic, safe-by-design canary resources (buckets, secrets, credentials, identities) across cloud environments. Canaries are isolated and contain no real data. When an attacker enumerates, accesses, or attempts lateral movement or privilege escalation, they touch a canary and an immediate, high-fidelity alert is generated. Integrates with existing security stacks (SIEM, EDR, CSPM) via lightweight connections (often Terraform) – no agents or network changes required. Deployable in minutes. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total funding raised – $25M (including a $20M Series A in March 2026) - **Notable Investors/Partners**: Accel, Tapestry VC, FirstMark Capital, MMC Ventures, CCL Industries, plus an undisclosed group of cybersecurity angels and advisors. - **Growth Signals**: - Recognised as a Euroscape Top Startup, Euro Seed Top 50, and Cloud 100 2025 London Startups to Watch. - Hiring across engineering, sales, and customer success in London, New York, and San Francisco. - Fast adoption: most teams deploy in minutes via Terraform. ## Competitive Advantages - **Deception-based detection** – does not rely on logs, rules, signatures, or anomaly models, making it effective against novel attacks and producing far fewer false positives. - **Safe by design** – canaries contain no real data and are isolated from production systems, eliminating risk while providing high-confidence alerts. - **Complements existing tools** – works alongside SIEM, EDR, and CSPM to add a post-breach detection layer without replacing them. - **Easy deployment** – no agents, no network changes; integrates via a lightweight connection (often Terraform) and manages canaries automatically as environments evolve. ## Strategic Focus - Scaling the platform to cover more cloud environments and attack paths. - Expanding go-to-market (sales and customer success) in the US and Europe. - Continuing to build a high-agency engineering team to stay at the forefront of cloud security deception. ## Why Work Here - **Culture**: Fast-moving, collaborative startup where you work directly with experienced founders who have scaled successful ventures before. High agency and curiosity are valued. - **Work policy**: On-site/hybrid – offices in Fitzrovia (London) and Manhattan (NYC). The company believes the best ideas come from working side by side. - **Perks**: Equity options at employee-friendly terms, cycle to work scheme, monthly socials & lunches, dinner provided if working late, fresh fruit, tea, coffee, soft drinks. - **Engineering culture**: Build meaningful security infrastructure in a high-growth industry; see the impact of your work daily; recognised for exceptional hiring standards (Cord award for speed and responsiveness). - **Open roles**: Founding Engineers, Sales Engineers, Account Executives, SDRs, and Customer Success positions available across London, NYC, and San Francisco. ## Sources 1.
