Remote flexibility
Undisclosed
The listing is advertised as remote but does not state which countries or regions candidates may work from.
Why this role is Undisclosed
We only label a role Work from anywhere, Region restricted or Work from home when the employer's own wording says so. We checked this advert under our current rules and found no country or region eligibility requirement in it. We don't guess, so it stays Undisclosed until the employer publishes enough location information. Here is exactly what the advert left out.
- Countries you can work from: Not stated. The advert only gives "Remote", which names no country you must live in.
- Whether the work is remote: Never mentioned. The role reached us through a remote job board, but the advert itself doesn't say the work is remote.
- Working hours: Not stated. No timezone overlap or set hours are mentioned, so assume nothing either way.
Worth a look all the same. Missing wording is usually a rushed job posting rather than a closed door, so ask where you can be based in your first message, before you write a tailored application.
What the employer says
- Source listing states candidate location: "Remote"
What Nomaders makes of it
- No residency or region requirement found in the job description
- Check with the employer before assuming you can work from abroad
The quotes above are the employer's own words; the reading is ours. Always check the original listing and employment terms before working from another country.
About the role
About Us
Turnkey builds secure, developer-first infrastructure for private key management, making it simple to create wallets, sign transactions, and automate on-chain actions through one elegant API – without ever exposing sensitive key material.
Our mission is to secure the open internet by making strong cryptography and key management the default. Turnkey was founded by the team behind Coinbase Custody – the world’s largest and most secure crypto custodian – whose work has helped protect over $100B in crypto across the industry.
Turnkey's team is low-ego, high-agency, and high-autonomy with more than 100 years of combined experience in cryptography, security, and low-level systems, building reliable infrastructure used at scale.
Role Overview
We are hiring a Senior Application Security Engineer to join Turnkey's team and help ensure our systems, pipelines, and runtime environments are secure by design and resilient at scale.
You'll embed directly with product and infrastructure engineering teams, shaping how security is integrated into every aspect of our architecture. This is a hands-on, builder role ideal for someone who enjoys building secure systems from the ground up.
What You’ll Do
You will partner with Product and Engineering at both the design and development stage to ensure that we implement new features securely, including (but not limited to):
Participating in the implementation efforts
Doing security reviews
Helping with product design decisions
Auditing and surfacing vulnerabilities in our current products
Conducting threat modeling and security assessments for new features and systems, identifying risks early and shaping secure architectural decisions.
Developing and improving our Automated Tooling: further enhancing our automated tooling to scale our product security capabilities and find potential code problems both before and after we deploy
Making the safe way, the easy way: work on defining and building application guardrails so that developers can build securely by default
Investigating and remediating security issues, including vulnerabilities and incidents, and drive long-term improvements to prevent recurrence
Embedding a culture of secure development across engineering, defining practices that influence how Turnkey builds, deploys, and maintains systems at scale.
What We're Looking For
Bachelors degree in Computer Science, Engineering, or a related field
5+ years of experience in application or product security, ideally in fast-moving, high-impact or crypto-native environments
Strong understanding of web, mobile, and cryptographic security fundamentals (e.g. OWASP Top Ten, SANS/CWE Top 25)
Proficiency in programming and scripting languages (Typescript/Javascript, Go, Rust) and experience building secure systems from the code up
Hands-on experience with security testing tools and methodologies (static/dynamic analysis, pen testing, etc.)
