About

Cybersecurity software development

Cybersecurity software development is product engineering with people who build secure tools: threat-detection systems, cloud scanners, and agents that run inside customer workloads.

On The Spot Development staffs that work in three areas: cloud-native runtime security, application security, DevSecOps, and agentic security.

What makes these teams hard to build is the combination: product engineering plus a security domain.

Who benefits

When a dedicated team for a cybersecurity product makes sense

01

You have a security product in the market with paying customers, and the roadmap is now moving faster than you can hire against it.

02

The roles are hard-to-fill: kernel and eBPF work, detection engineering, pipeline security.

03

Your engineering leadership sits in Israel, the UK or the US, and you want the second team inside CET working hours rather than twelve hours away.

04

You want to hold the contract, the roadmap and the right to buy the team out when it will be needed.

05

You are hiring in Poland for the first time. Beyond basic job boards, we source our security team directly via GitHub research, closed tech communities, and private Slack/Discord groups.

Why On The Spot Development

Why security companies stay with us

Security is our largest domain

75 of our engineers work on security products, more than in any other domain we staff. Two of those accounts are public: Orca Security (since 2019) and Cycode.

The team is yours alone

Each engineer works full-time on one product. We don't rotate people between accounts or park them on a bench between projects.

You make the hiring decision

We source and prescreen technically, then present profiles. You run the technical round, or our CTO or a technical expert runs it on your behalf, to your criteria. Either way the decision is yours, and no offer goes out before you make it.

You can buy the team out

The right to hire the team into your own company exists from day one. It is not tied to a term, a milestone or a waiting period.

We name the slow roles first

Some security searches take months: kernel, eBPF, low-level Rust. We have filled them, and we tell you which of your roles could fall into that group.

The team keeps learning

Our team leads meet across accounts on real cases: review practice, incidents, hiring calls. As AI changed how engineering gets done, these sessions became where we work out adoption, metrics, agent workflows and tooling: what holds up on a production team.

Four ways security companies work with us

What we work with

What building a security product actually takes

Runtime and kernel

Agents that live inside customer workloads and must not slow them down. eBPF for low-overhead observation, Linux and Windows internals, container and Kubernetes runtimes, serverless environments where conventional monitoring does not install. The work is measured in overhead and latency. Go, C++, Rust.

Detection engineering

Turning attacker behaviour into rules that fire on real activity and stay quiet otherwise: privilege escalation, container escape, living-off-the-land techniques, cloud reconnaissance. The hard part is keeping the false positive rate low enough to still read the alerts.

Application and supply chain security

Static analysis engines, scanners built for monorepos, ephemeral environments, GitOps workflows and machine-generated code. Correlating findings from many tools into one prioritised view instead of a long queue. Rust and Go for the engines, TypeScript and React for the interfaces people actually work in.

Cloud and delivery infrastructure

AWS, Google Cloud, Azure, Kubernetes, Docker, Terraform, Helm, Pulumi. Building the pipeline and writing the runbook around it.

Cryptographic and key security

Multi-party computation, key custody, hardware security module integration. Memory-safe languages are the requirement. Rust, WebAssembly.

Data and telemetry

Kafka, PostgreSQL, MongoDB, Elasticsearch, Redis on the data path; Prometheus, Grafana, OpenTelemetry, Datadog for watching it.

Our process

From scope call to first commit

Scope call

Which roles, which parts of the product, which threat model. You leave the call with a realistic timeline per role.

01

First profiles in 3 to 5 days

Real CVs with real salary numbers, prescreened for skills, English and motivation. You run the technical round, or our CTO or a technical expert runs it to your criteria.

02

Offer and contract

We handle the offer, the Polish employment contract, IP assignment and equipment. You approve the level and the number; the paperwork is ours.

03

First engineers embedded

Your repositories, your board, your review process, your definition of done. We handle employment, payroll, equipment and the Warsaw office from day one.

04

Second wave

We check in after the first month, while impressions are still specific and anything worth correcting is cheap to correct. With the bar calibrated against real candidates, the following roles move faster than the first ones did.

FAQ

Frequently asked
questions

Every engineer signs an NDA and an IP assignment before they see anything of yours. The work product is yours, set out in the contract. Access is granted inside your own systems, under your access controls, and revoked by you when an engineer rolls off. We are the employer, you are the one who decides what they can reach.

Cloud-native runtime security, where our teams work on agentless scanning of public and private cloud infrastructure and on a runtime sensor that observes workloads at the kernel level. Application security with DevSecOps, where the work is securing delivery pipelines and correlating events across the software development lifecycle.

Yes. The Orca Sensor team uses eBPF to keep the runtime footprint small on Linux, Windows and Kubernetes, and the same account covers kernel and low-level Rust work.

You do. We source, prescreen technically and present profiles, then you interview every candidate, or our CTO or a tech expert can run it to your criteria. Nobody joins your team without your decision, and you see the same information about each candidate that we do.

Hard-to-fill security roles take long, sometimes months, because the people who can do the work are already employed or not actively looking for a job. We give you the range for your specific role upfront.

Yes. Each engineer works full-time on one customer product.

Our engineers work inside the customer's own security processes: their onboarding, their access controls, their review requirements. Secure SDLC practice and OWASP guidance are the working default, and teams in Poland operate under GDPR.

Warsaw, Poland. Teams work from the office, remotely or in a hybrid pattern, whichever your engineering leadership prefers. Poland sits in CET, which gives a full working-day overlap with Israel and the UK and a partial one with the US East Coast.

Often not yet. If the product still changes shape every few weeks, or your stack gets rewritten monthly, a team in another country will spend its time waiting for direction. Senior technical leadership through our Fractional CTO engagement is usually the better first step.

Yes. ShardX, a crypto custody startup we staffed from 2018, was acquired by Gemini in 2021 together with the whole engineering team we had built. Eight of our customers have been through an M&A.

Each model trades control against speed and cost differently. The custom software development page sets the models side by side, including where our own model is the wrong choice. Compare the models.

Tell us early. We are the employer, so the search starts again on our side and you are not paying twice for the same role. The reason usually surfaces in the first month, which is why we ask for feedback.

Tell us which security roles you need

Send us the roles and the part of the product they will work on. We will come back with a timeline per role and what each one costs in Poland.
