Senior Software Engineer (m/f/d): AI-Native Development

Das ist der Job

You start from the problem and the constraints, not from a favorite language.

Darum lohnt es sich

Our customers trust us with business-critical traffic, and we build and operate to the highest standards of certification for critical infrastructure.As a Senior Software Engineer (m/f/d), you will help your team design and build robust solutions for complex problems.

We strongly believe in “you build it, you run it, you own it” and a “collaboration culture”, where you and the team are on the frontlines and driving the change together!

Your Responsibilities Own features end-to-end, from backend service design through to the frontend slice the feature needs, in an international, cross-functional team of software engineers, QA and OPS professionalsDesign, validate and advocate architecture decisions for your team’s verticals, with a bias toward well-structured, service-oriented backendsWork AI-natively: use AI coding agents as core tooling to move faster and raise quality, while staying fully accountable for the code you shipDrive technical discussions and decisions with your teamPush toward continuous delivery, improving both the software and how we build itWrite code that performs, and holds up in production under hostile, high-volume traffic, with security and input validation built in from the startYour QualificationsYou think in systems.

You treat AI coding agents as core tooling; you know their strengths and limits, and you own the outcome (including reviewing AI-written code for exactly the security and validation gaps above)You reason comfortably about the whole picture: APIs, services, data, and the frontend the feature owns; you don’t stop at a language boundaryYou're at home on Linux systems, and CI/CD pipelines, containerization (Docker), and deployment considerations are a natural part of how you think about shipping software, not foreign territoryCurious by default; you like to validate ideas hands-on with POCs and RFCsAt home in an agile team with structured requirements, and quick to learnYou speak and write English fluentlyAbout usWe protect the real world against digital threats: This is the mission the Myra Security team pursues with utmost passion.

Job DescriptionWe protect our customers’ digital infrastructure, keeping it secure, fast, and online, even under active attack. As a cybersecurity provider, we run high-performance systems in a genuinely hostile environment, where code quality, security, and rigorous input validation are not hygiene: they are the product.

We are looking for someone who thinks in systems, who starts from the problem, reasons about the trade-offs of the environment it will run in, and reaches for the tool that fits, rather than the one on their CV.

We are constantly improving our applications and we work AI-natively: AI coding agents are part of how we spec, build, and review every day.

To you the difference between languages is largely syntax; what actually matters is the environment code runs in: performance, portability, compatibility, operational cost, and long-term maintenanceYou can explain your choices.

You can walk us through a time you chose one language or runtime over another, and the trade-offs that drove the decision, and you can do the same for the frontend when a feature calls for itYou’ve gone deep, not just broad.

At least 5 years of intensive, hands-on coding and engineering experience — this is a senior role and not a fit for juniors — with genuine depth in at least one or two ecosystems. Our stack today is mostly PHP / Symfony, React and GraphQL; Edge systems use C, Rust and Python mostly. We care a lot about experience with Python, Go, C and/or Rust.

These are parts that are being introduced to our dev department and where a significant part of our edge logic is based in, and someone who already reasons and builds fluently in them will make an outsized difference; this is a real signal for us, not a nice-to-have footnoteSecurity and code quality are instincts, not afterthoughts.

You write code that holds up under hostile, high-volume traffic; you treat every input as untrusted, validate rigorously, and understand how a weak boundary or a hot-path regression becomes an attack surface. Reliability under load is a first-class concern for youYou’re fluent with AI-assisted development.

The digital protection of companies, critical infrastructure, and government agencies is critical for the survival of our society. As a German technology manufacturer, Myra offers a secure, certified Security-as-a-Service platform for protecting digital business processes.

Smart Myra technology monitors, analyzes, and filters malicious internet traffic before virtual attacks can do any real harm. We strive to provide an inclusive work environment where you feel accepted and equal.
