About the Role
We're building a global commerce platform to power
$1T+
in annual transactions for millions of SMEs. Our SDE V (Staff) is the technical force?multiplier who
sets the architecture
,
raises the reliability bar
, and
multiplies team effectiveness
. You'll steward our core payments models--
subscriptions, payments , reconciliation , tax
--and the services around them, ensuring
correctness by design, auditability, and delightful performance at scale
. This is an
IC role with org?level influence
(no direct reports), focused on designing systems, shaping standards, and growing engineers.
Stack:Backend:
Go, ConnectRPC, Buf
Frontend:
Vue.js, Vite, Webpack MFA, TanStack Query
Databases:
MongoDB, Firestore, ClickHouse
Cloud:
GCP (GKE), Pub/Sub, Redis, OpenTelemetry
What You'll Do
Architect and ship multi?tenant, planet?scale services
(checkout, subscriptions, payments orchestration, invoicing, tax hooks) with clear domain boundaries (DDD) and hard SLOs.
Be the custodian of API & schema design
: own protobuf/ConnectRPC conventions, versioning policy, deprecation playbooks, and Buf breaking?change checks--so our contracts
stand the test of time
.
Guarantee resilience & availability
of core payment paths: timeouts, retries with jitter, circuit breakers, idempotency keys, outbox/Saga patterns, hedged requests, and graceful degradation.
Ensure complete auditability
: append?only double?entry ledger, immutable event streams, trace?linked entities (OTel trace/span IDs), tamper?evident trails, and reconciliations that tie out to the cent.
alerting that wakes humans only for user?impacting issues
.
Production excellence
: canary/blue?green rollouts, automated rollbacks, chaos drills, DR playbooks (RPO/RTO), multi?region failover strategies, and incident command on rotation.
Security & compliance by design
: PCI scope minimization, tokenization/vaulting, secrets/KMS hygiene, data retention/archival, and privacy controls--embed checks in CI/CD.
Developer acceleration
: pave golden paths (service templates, ADR/RFC process, linting/formatting, contract tests, ephemeral envs, load/perf harnesses) to make the right thing the easy thing
What You'll Lead
Core domain evolution:
orchestration ledger reconciliation flows with crisp invariants and consistency guarantees (read?your?writes where needed, eventual where appropriate).
Reliability strategy:
SLIs/SLOs, error budgets, capacity planning,
cost/FinOps
guardrails, multi?region posture, and DR exercises.
design reviews, postmortems, technical strategy, coding standards, and mentorship across teams--
raise the bar for the org
.
Hiring & team growth:
help us
hire, scale, and train
the right team; shape interview loops, rubrics, onboarding, and ongoing learning (brown bags, reviews, pair design).
Cross?functional partnership:
collaborate with Product/Marketing/Support to translate platform capabilities and constraints into roadmaps, GTM narratives, and reliable customer outcomes.
Risk & roadmap:
maintain a technical risk register, make
build?vs?buy
calls, and propose simplifications or deprecations that meaningfully reduce complexity and MTTR.
Minimum Qualifications
10+ years
building and operating backend systems (at least
5+ years in Go
), with
2-3+ years
acting as a Staff/Principal?level IC or Tech Lead for critical paths.
Deep proficiency with protobuf + ConnectRPC/gRPC
and API lifecycle management (versioning, compatibility, contract testing, Buf).
: secrets/KMS best practices, PCI basics (scope reduction, key rotation), and data governance (retention/archival).
Testing discipline
: unit, integration, contract, property?based, performance; test data management and deterministic environments.
Frontend collaboration
: solid understanding of
Vue.js
+ TanStack Query
to shape clean API surfaces and performance budgets across the boundary.
Exceptional technical writing & communication
: design docs, ADRs/RFCs, postmortems, and stakeholder updates.
Nice to have
Hands?on integrations with major PSPs/local rails (e.g., UPI, wallets, BNPL, cards/3DS2) and reconciliation at scale.
Experience with active?active or multi?region designs; chaos engineering; traffic management.
Observability leadership with OpenTelemetry at org scale (tail?based sampling, exemplars).
FinOps experience: cost baselining, quotas, budget alarms, and workload right?sizing.
Familiarity with regulatory frameworks (PCI DSS, SOC 2/ISO 27001) and privacy laws relevant to our markets.
How we work
Pragmatic architecture with a bias to ship, measure, iterate.
High ownership, low ego: design docs, incident reviews, data?driven decisions.
Product?first mindset: we sweat the merchant and buyer experience.
IC leadership: influence through design, docs, prototypes, and mentorship--not headcount.
