Who are we?
We’re a passionate team of builders who are dedicated to delivering solutions that empower people. Today, we’re leveraging Ai and gamification to build a vertical platform that is centered around improving the safety readiness of frontline workers in any high risk industry. If you are a doer who thrives in a dynamic, mission-focused environment, join us!
Who are we looking for?
As a Senior Backend Engineer, you’ll design and build the core services that power our platform: APIs, identity and authorization, content and training workflows, telemetry and insights pipelines, and integrations with enterprise customer systems. You’ll work closely with Product, Frontend, DevOps/Platform, and Game Content teams to ship backend capabilities that are reliable, secure, and scalable.
This is a hands-on senior role with real ownership: you’ll lead technical design, raise quality, and help us evolve our architecture as we scale customers, use cases, and modalities.
Key responsibilities:
Design and implement backend services in Go that are secure, observable, and resilient (clear SLIs/SLOs, structured logging, metrics, tracing).
Own API architecture (REST/gRPC), versioning, and backward compatibility for internal + external consumers.
Expertise in resource oriented design patterns
Build on platform’s foundations such as:
Multi-tenant data modeling and isolation
Identity, authN/authZ (RBAC/ABAC), audit trails
Learning/training lifecycle services (assignment, completion, outcomes, reporting)
Content and module metadata workflows
Event-driven telemetry and insights pipelines
Integrate with customer ecosystems (SSO/SAML/OIDC, SCIM, LMS/LXP, webhooks, data exports, APIs).
Partner with Platform/Infra on deployment patterns, reliability, and cost/perf improvements (containers, CI/CD, runtime tuning).
Lead by example: write high-quality code, drive pragmatic architecture decisions, mentor others, and strengthen engineering standards.
What success looks like (first 3–6 months)
You ship meaningful backend improvements that reduce friction in the user journey (admins/managers/learners)
You improve service quality: improve reliability and observability
You take ownership of one or more domains (e.g., identity/integrations, telemetry/insights, training workflows) and become the go-to engineer for it.
You raise the bar on design docs, code reviews, and “how we build” across the backend team.
Requirements
Strong Go (Golang) experience building production backend systems.
Proven ability to design scalable distributed services (microservices or modular monoliths), including data modeling and API design.
Experience with relational databases (e.g., Postgres) and practical performance tuning (indexes, query patterns, migrations).
Comfort with cloud-native environments and modern delivery (containers, kubernetes, CI/CD, infra-as-code concepts).
Solid understanding of security fundamentals (auth, least privilege, secrets, OWASP basics) and building for enterprise expectations.
A collaborative, product-aware mindset: you care about real users, not just code.
Nice to have
Familiarity with gRPC and Protocol buffers.
Caching and performance layers (Redis), rate limiting, and idempotency patterns.
Observability stacks (OpenTelemetry, Prometheus, Grafana, ELK, Datadog).
Experience with enterprise integrations: SAML/OIDC, SCIM provisioning, LMS standards (xAPI/SCORM/LTI) or similar.
Experience in B2B SaaS with multi-tenant constraints and compliance expectations.
Exposure to Security and compliance standards (ISO/SOC2)
Exposure to media/streaming/real-time systems (not required, but relevant).
Our (typical) stack:
Go, gRPC/REST
Postgres, Redis
Docker, Kubernetes (or managed container runtime)
AWS
Observability (OpenTelemetry + metrics/logging/tracing)
How we work
Small teams, high ownership, low bureaucracy.
Pragmatic engineering: strong fundamentals, measured architecture, ruthless clarity about outcomes.
We invest in maintainability (tests, automation, docs) because the platform must be trusted.
How do we support and benefit our employees?
Fully remote set-up, with 2x company-wide meetups per year to meet and bond with your colleagues.
All the equipment you need to succeed provided by Pixaera.
25 days of company vacation allowance per year in addition to local public holidays. If there is a public holiday that you would rather work, let us know and you can swap it for another day in lieu.
Competitive stock options.
At Pixaera, we’re committed to building a workplace where everyone feels respected, supported, and empowered to thrive. We believe that diverse perspectives fuel creativity and innovation, which is why we celebrate individuality and foster an environment of inclusion and belonging.
We’re proud to be an equal opportunity employer — discrimination of any kind has no place here. No matter your background, identity, or lived experience, you’re welcome at Pixaera.
