About Obinex
Obinex is the first fully gamified centralized exchange (CEX), where finance meets game mechanics and NFT-powered experiences. We\’re building the platform that will redefine how millions of users interact with trading, staking, and digital economies.
Our MVP is in development, and we\’re assembling a global founding team. Now we\’re looking for a DevSecOps Engineer to establish the core security and infrastructure of Obinex from day one.
What will you do?
As our
Backend Engineer
, you will be responsible for architecting the backbone of a high-performance exchange. This means not just writing code, but designing systems that scale to millions of users while meeting the highest security and compliance standards.
You\’ll:
- Design and implement
low-latency distributed systems
(trading engine, order book, messaging). - Build scalable APIs and microservices in
Golang and Rust
. - Ensure concurrency, parallelism, and performance optimization at scale.
- Collaborate with DevSecOps to embed
security-first practices
across the backend. - Mentor engineers and help set the
technical culture
of Obinex. - Translate complex architecture decisions into clear, long-term strategies.
What You\’ll Do in the First 12 Months
- Architect and deliver the
exchange\’s trading engine and order book
. - Design fault-tolerant systems with
SLA targets close to 99.999% uptime
. - Implement event-driven architectures (Kafka, NATS, RabbitMQ).
- Optimize databases for scalability (PostgreSQL, Redis, NoSQL, time-series DBs).
- Embed
cryptographic standards, KYC/AML hooks, and compliance requirements
into backend systems. - Integrate with custody solutions like
Fireblocks or Anchorage
. - Continuously improve systems with monitoring, observability, and autoscaling.
Requirements (Mandatory)
- 8+ years of backend engineering experience.
- Proficiency in Golang and Rust.
- Deep expertise in distributed systems, concurrency, and parallelism
. - Experience with
event-driven architecture
(Kafka, NATS, RabbitMQ). - Strong background in PostgreSQL, NoSQL (MongoDB, DynamoDB), and caching (Redis, Memcached).
- Familiarity with
cloud-native architectures
(AWS/GCP/Azure) and IaC (Terraform, Kubernetes). - Knowledge of
security practices
(cryptography, secret management, OWASP Top 10). - Experience in
regulated environments
(fintech, banking, crypto CEXs).
Nice to Have:
- Exposure to time-series databases (InfluxDB, Timescale).
- Experience designing
ledger-like storage
(immutable, auditable). - Familiarity with SOC 2, ISO 27001, PCI DSS compliance.
- Prior work on trading platforms or high-frequency systems.
What We Offer
- Equity from day one
in a global fintech startup. - Base salary
starting once our $5M fundraising round closes (currently in progress). - A role with massive ownership:
you\’ll design the infrastructure and security backbone of Obinex. - Direct exposure
to regulatory-grade challenges in fintech + Web3. - Real opportunity
to grow into Head of DevSecOps within 18–24 months. - Global, remote-first culture, obsessed with execution and innovation.
