With
Agentic AI live in production , Keepnet runs autonomous systems that plan, build, and operate security awareness and human risk workflows, supported by strong guardrails and observability.
We’re looking for a
Senior Backend Developer
who wants to build production-grade backend services that power these systems, working in a multinational, AI-first engineering team where quality, ownership, and long-term thinking matter.
What You’ll Do
Design, build, and maintain
scalable backend services
for Keepnet’s Human Risk Management platform.
Build
clean, modular APIs
that integrate internal services and third-party systems to enable automation, reporting, and security workflows.
Develop
testable, maintainable codebases
using principles such as Clean Architecture, DDD, and TDD.
Own the
full development lifecycle : design, implementation, CI/CD (Azure), and post-release monitoring.
Work on
distributed and asynchronous systems
using message queues, background workers, and event-driven workflows.
Use
observability signals
(logging, metrics, tracing, tools like Sentry) to proactively detect, diagnose, and prevent production issues.
Collaborate closely with
frontend, product, and customer-facing teams
to deliver features that solve real customer problems.
Participate in
Agile ways of working , focused on iteration, ownership, and continuous improvement.
What We’re Looking For
8+ years of experience
building backend systems with
.NET .
Strong understanding of
API design , distributed systems, and asynchronous architectures.
Experience with
SQL and NoSQL databases
(PostgreSQL preferred), caching, and queuing systems.
Familiarity with
cloud environments and DevOps practices
(Azure preferred).
Comfort working on
production SaaS platforms , with ownership beyond deployment.
Experience using
AI-assisted development tools
(e.g. Cursor or similar) to support code exploration, refactoring, testing, or design discussions—while maintaining strong engineering judgment.
A strong sense of
ownership and production accountability , including monitoring, debugging, and continuous improvement.
Ability to understand
product and business context , making pragmatic technical decisions that balance user value, risk, and long-term goals.
A
security-conscious mindset , building systems that are secure by design.
Life at Keepnet At Keepnet, engineering is about
craft, collaboration, and impact .
What you can expect:
Hybrid Working:
A balance of in-office collaboration and remote focus time.
Thoughtful Engineering:
Time and space to design systems properly, not just ship quickly.
Global Context:
Work on a multinational SaaS platform used across multiple regions.
AI-First Environment:
AI-assisted development and production-grade AI systems are part of everyday work.
Annual Leave:
25 days (+1 per year of service).
Health & Well-being:
Gym support and cycle-to-work scheme.
Team Culture:
Monthly team lunches and quarterly offsites.
Continuous Learning:
Learn from experienced peers and grow your skills over time.
Why This Role Is Different This role is for engineers who:
Care about
system design and long-term maintainability
Enjoy working with
experienced peers who challenge each other constructively
Prefer
preventing incidents
over reacting to them
Want to build software used by
real customers at real scale
Believe good engineering is as much about
ownership and judgment
as it is about code
If that sounds like you, we’d love to talk.
