Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineer (Python) - **Company:** Telnyx - **Location:** United States - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Amazon Web Services, Microsoft Azure, Bash Shell, Border Gateway Protocol, Network Operating System (NOS), Cloud Computing, Computer Networks, Software Debugging, Linux, Domain Name System (DNS), Github, Jinja (Template Engine), Python (Programming Language), Network Layer, PostgreSQL, Network Control, Network Installation Services, Routing, Queueing Systems, RabbitMQ, Ansible, Prometheus, SQLAlchemy, Openapi, Network Switches, Google Cloud, Backend, Pytest, Bare Metal, Hashicorp, Firewall Services Module, Oracle Cloud Infrastructure, Docker, Crud - **Published:** August 26, 2026 - **Apply:** https://job-boards.greenhouse.io/telnyx54/jobs/7978364003 ## About the Role * You've built and operated customer-facing REST APIs over real infrastructure - APIs where a POST ends in a router being configured, not just a row inserted - and you've lived with the async-job, rollback, and eventual-consistency problems that creates. * Strong async Python in production, and comfortable writing and reviewing Go. * Working routing knowledge: you can configure and debug BGP sessions, VRFs, GRE tunnels, NAT, and WireGuard, and read FRR or VyOS configs. Certification not required; hands-on ability is. * Postgres beyond ORM basics - migrations on live systems, locking semantics, queue patterns. * Fleet automation over SSH - Ansible at production scale, idempotent roles, safe rollout/rollback, drift detection. * You've debugged incidents across layers in one sitting - tcpdump, wg show, vtysh, and application logs - ending in either a code fix or a config fix, and knowing which. Bonus points for * Envoy/xDS control-plane work (go-control-plane, ADS snapshots). * Cloud interconnect products - AWS Direct Connect, Azure ExpressRoute, GCP Partner Interconnect, or Equinix Fabric/Metal provisioning APIs. * IPAM internals (NetBox or equivalent), address-plan and route-distinguisher design. * Linux * VyOS (or equivalent NOS) migration experience on live customer traffic. * Mobile core exposure - routing toward PGW/PCEF/EPC, GRE toward packet gateways. * OpenAPI spec authorship and public developer documentation. * Operating multi-site PoP fleets (bare metal + Equinix-hosted). ## Description * The orchestration control plane (Python 3.12, asyncio) - translating POST/DELETE into network deployments: resource allocation (IPAM, port/route-distinguisher/GRE-ID pools), Postgres-backed job queues (SKIP LOCKED), retries, rollback on partial failure, deploy/decommission runners, and long-running health-check and reconciliation daemons. * The network automation layer - Ansible + asyncssh/netmiko pushing Jinja2-templated config to a fleet of Linux and VyOS nodes: WireGuard interface and peer lifecycle, FRR/VyOS BGP (VRFs, route reflectors, BGP labels), GRE tunnels, static NAT and firewall rules, Unbound DNS, anycast announce/withdraw driven by health checks, and config-drift detection. * Cloud interconnect integrations - Equinix Fabric and Equinix Metal APIs to land virtual cross connects into AWS, Azure, and Google Cloud regions. * Envoy-based data planes - a Go xDS control plane on envoyproxy/go-control-plane, pushing CDS/RDS/EDS over ADS to edge and gateway Envoy fleets. * Production - Prometheus/Telegraf metrics and alerting, Bugsnag, customer escalations that span app logic and the network, and billing sync (MRC) for network resources. Tech stack (what you'll actually touch) * Languages: Python (asyncio: aiohttp, uvloop, SQLAlchemy, Alembic, aiopg), Go (Envoy control plane), Jinja2, Bash * Data: PostgreSQL (schema design, migrations, advisory locking, as a job queue), RabbitMQ * Network OS / routing: VyOS, FRR, Linux networking (VRFs, netfilter/NAT, netplan, GRE, WireGuard), BGP (VRFs, route reflectors, communities/labels, anycast), Unbound * Automation: Ansible / ansible-runner, netmiko, asyncssh, NetBox-style IPAM (pynetbox, netaddr) * Proxy / data plane: Envoy, xDS (ADS, go-control-plane) * Vendor & cloud: Equinix Fabric, Equinix Metal, AWS / Azure / GCP interconnect regions * Platform: Docker/OCI, GitHub Actions, HashiCorp Vault, OpenAPI 3 + Redocly, pytest (unit * e2e), mypy/ruff/black * Architecture: clean/hexagonal (usecases, repository interfaces, adapters) - the service is structured, not a script pile, * Not a NetOps/NOC role. The deliverable is software - APIs, control planes, automation - not manual device changes. * Not a pure backend CRUD role. If the network layer in the stack above reads as someone else's problem, this is the wrong fit., What is your base salary expectation?

Classification of protected categories is as follows: A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability. A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service. An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense. An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.
