01Why Hexcore

The bar is the
whole point.

01

Senior-only teams

No graduate intakes. The median engineer here has 7+ years of production experience. You'll review code with people who can outpace you on their bad days.

02

World-class compensation

Senior engineers earn against US / EU bands, not local market rates. Bands are published internally. Reviewed annually.

03

Real engineering problems

Payments, fraud, identity, fulfillment, AI-native systems. Our clients hire us when the stakes are real — we don't treat critical systems as a learning opportunity.

04

Operational ownership

You build it, you run it. On-call is paid, dashboards are not negotiable, and postmortems are written — not avoided.

05

Remote-first, written culture

Fully remote, worldwide. Design docs before code. Async by default. Meetings have agendas or they get cancelled. Documentation is engineering, not overhead.

06

Growth, honestly

Conference budget, paid open-source time, internal rotations across practices. We'd rather lose a great engineer to a great opportunity than keep a stagnant one.

Send your CV to hr@hexcore.ng

Build production-grade user interfaces for clients whose front-end is their product. You'll own delivery end-to-end — from design review through performance budgets and the on-call rotation.

What you'll do
  • 01Design and ship customer-facing applications in React and Next.js (App Router).
  • 02Set and enforce performance budgets — Core Web Vitals are not optional.
  • 03Pair with designers on the spec, then own the component model end-to-end.
  • 04Mentor mid-level engineers and review code with the seriousness of a co-author.
  • 05Carry an on-call rotation for the systems you helped build.
What we're looking for
  • →6+ years of production frontend experience, with at least 3 in React.
  • →Deep working knowledge of Next.js — RSC, streaming, caching, route handlers.
  • →Strong opinions on accessibility, performance, and design systems.
  • →Comfortable reading and contributing to backend code when the seam crosses.
  • →Track record of shipping — public links, GitHub, or written engineering content preferred.
Bonus, not required
  • +Experience with Figma-to-code workflows and design tokens.
  • +Open-source contributions to the React / Next.js ecosystem.

Apply for this role

Send your CV to hr@hexcore.ng

Design and run the scalable systems behind our clients' critical workloads — payments, fraud, identity, fulfillment. Production stakes are real, and so is the engineering bar.

What you'll do
  • 01Design services in Go and Java for throughput, correctness, and operability.
  • 02Model data on PostgreSQL with an eye on indexes, query plans, and locking.
  • 03Build event-driven pipelines on Kafka — partitioning, idempotency, replay.
  • 04Use Redis well (and know when not to use it).
  • 05Operate what you ship — dashboards, alerts, runbooks, postmortems.
What we're looking for
  • →7+ years building production backend systems at scale.
  • →Strong proficiency in Go and Java — you can switch between them in the same week.
  • →Deep PostgreSQL fluency: query planning, transactions, isolation levels.
  • →Hands-on Kafka experience in production — not just a tutorial.
  • →Comfortable in AWS: EC2, ECS/EKS, RDS, IAM, VPC fundamentals.
  • →You write design docs before you write code, and you publish postmortems.
Bonus, not required
  • +Experience with payment systems, fraud platforms, or financial infrastructure.
  • +OpenTelemetry / distributed tracing in anger.

Apply for this role

Send your CV to hr@hexcore.ng

Own the platform our engineers ship on. Build the infrastructure, the CI/CD spine, and the observability stack that lets a senior team deliver without ceremony.

What you'll do
  • 01Own infrastructure-as-code across AWS and GCP — Terraform is the source of truth.
  • 02Operate Kubernetes clusters in production. Capacity, autoscaling, upgrades, the works.
  • 03Design and maintain CI/CD pipelines that engineers actually trust.
  • 04Stand up the observability stack — metrics, logs, traces, SLOs, alert routing.
  • 05Lead incident response. Lead postmortems. Lead the prevention work that follows.
  • 06Harden the security posture: IAM, secrets, network policy, compliance evidence.
What we're looking for
  • →6+ years operating production infrastructure at scale.
  • →Deep working knowledge of both AWS and GCP — not one with a tourist visa for the other.
  • →Terraform fluency across modules, state management, and drift remediation.
  • →Production Kubernetes operations, including upgrades and disaster recovery drills.
  • →Comfortable owning the on-call rotation and the calmness it requires.
Bonus, not required
  • +ISO 27001 / SOC 2 evidence collection experience.
  • +Cost engineering — measurable savings via right-sizing, commitments, or architecture.
